Africa is the world's second largest and second most-populous continent, being behind Asia in both categories. At about 30.3 million km2 including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area. With 1.2 billion people as of 2016, it accounts for about 16% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, the Isthmus of Suez and the Red Sea to the northeast, the Indian Ocean to the southeast and the Atlantic Ocean to the west; the continent includes various archipelagos. It contains 54 recognised sovereign states, nine territories and two de facto independent states with limited or no recognition; the majority of the continent and its countries are in the Northern Hemisphere, with a substantial portion and number of countries in the Southern Hemisphere. Africa's average population is the youngest amongst all the continents. Algeria is Africa's largest country by area, Nigeria is its largest by population. Africa central Eastern Africa, is accepted as the place of origin of humans and the Hominidae clade, as evidenced by the discovery of the earliest hominids and their ancestors as well as ones that have been dated to around 7 million years ago, including Sahelanthropus tchadensis, Australopithecus africanus, A. afarensis, Homo erectus, H. habilis and H. ergaster—the earliest Homo sapiens, found in Ethiopia, date to circa 200,000 years ago.
Africa encompasses numerous climate areas. Africa hosts a large diversity of ethnicities and languages. In the late 19th century, European countries colonised all of Africa. African nations cooperate through the establishment of the African Union, headquartered in Addis Ababa. Afri was a Latin name used to refer to the inhabitants of then-known northern Africa to the west of the Nile river, in its widest sense referred to all lands south of the Mediterranean; this name seems to have referred to a native Libyan tribe, an ancestor of modern Berbers. The name had been connected with the Phoenician word ʿafar meaning "dust", but a 1981 hypothesis has asserted that it stems from the Berber word ifri meaning "cave", in reference to cave dwellers; the same word may be found in the name of the Banu Ifran from Algeria and Tripolitania, a Berber tribe from Yafran in northwestern Libya. Under Roman rule, Carthage became the capital of the province it named Africa Proconsularis, following its defeat of the Carthaginians in the Third Punic War in 146 BC, which included the coastal part of modern Libya.
The Latin suffix -ica can sometimes be used to denote a land. The Muslim region of Ifriqiya, following its conquest of the Byzantine Empire's Exarchatus Africae preserved a form of the name. According to the Romans, Africa lay to the west of Egypt, while "Asia" was used to refer to Anatolia and lands to the east. A definite line was drawn between the two continents by the geographer Ptolemy, indicating Alexandria along the Prime Meridian and making the isthmus of Suez and the Red Sea the boundary between Asia and Africa; as Europeans came to understand the real extent of the continent, the idea of "Africa" expanded with their knowledge. Other etymological hypotheses have been postulated for the ancient name "Africa": The 1st-century Jewish historian Flavius Josephus asserted that it was named for Epher, grandson of Abraham according to Gen. 25:4, whose descendants, he claimed, had invaded Libya. Isidore of Seville in his 7th-century Etymologiae XIV.5.2. Suggests "Africa comes from the Latin aprica, meaning "sunny".
Massey, in 1881, stated that Africa is derived from the Egyptian af-rui-ka, meaning "to turn toward the opening of the Ka." The Ka is the energetic double of every person and the "opening of the Ka" refers to a womb or birthplace. Africa would be, for the Egyptians, "the birthplace." Michèle Fruyt in 1976 proposed linking the Latin word with africus "south wind", which would be of Umbrian origin and mean "rainy wind". Robert R. Stieglitz of Rutgers University in 1984 proposed: "The name Africa, derived from the Latin *Aphir-ic-a, is cognate to Hebrew Ophir." Ibn Khallikan and some other historians claim that the name of Africa came from a Himyarite king called Afrikin ibn Kais ibn Saifi called "Afrikus son of Abrahah" who subdued Ifriqiya. Africa is considered by most paleoanthropologists to be the oldest inhabited territory on Earth, with the human species originating from the continent. During the mid-20th century, anthropologists discovered many fossils and evidence of human occupation as early as 7 million years ago.
Fossil remains of several species of early apelike humans thought to have evolved into modern man, such as Australopithecus afarensis (radiometrically dated to 3.9–3.0 million years BP, Paranthropus boisei and Homo ergaster have been discovered. After the evolution of Homo sapiens sapiens 150,000 to 100,000 years BP in Africa, the continent was populated by groups of hunter-gatherers; these first modern humans left Africa and populated the rest of the globe during the Out of Africa II migration dated to 50,000 years BP, exiting the continent eith
White Americans are Americans who are descendants from any of the white racial groups of Europe, the Middle East and North Africa or in census statistics, those who self-report as white based on having majority-white ancestry. White Americans constitute the historical and current majority of the people living in the United States, with 72% of the population in the 2010 United States Census. Non-Hispanic whites totaled about 197,285,202 or 60.7% of the U. S. population. European Americans are the largest ethnic group of White Americans and constitute the historical population of the United States since the nation's founding; the United States Census Bureau defines white people as those "having origins in any of the original peoples of Europe, the Middle East or North Africa." Like all official U. S. racial categories, "White" has a "not Hispanic or Latino" and a "Hispanic or Latino" component, the latter consisting of White Mexican Americans and White Cuban Americans. The term "Caucasian" is synonymous with "white", although the latter is sometimes used to denote skin tone instead of race.
Some of the non-European ethnic groups classified as white by the U. S. Census, such as Arab Americans, Jewish Americans, Hispanics or Latinos, may not identify as or may not be perceived to be, white; the largest ancestries of American whites are: German Americans, Irish Americans, English Americans, Italian Americans, French Americans, Polish Americans, Scottish Americans, Scotch-Irish Americans, Dutch Americans, Norwegian Americans and Swedish Americans. However, the English Americans and British Americans demography is considered a serious under-count as the stock tend to self-report and identify as "Americans", due to the length of time they have inhabited the United States if their family arrived prior to the American Revolution; the vast majority of white Americans have ancestry from multiple countries. Definitions of, "White" have changed throughout the history of the United States; the term "White American" can encompass many different ethnic groups. Although the United States Census purports to reflect a social definition of race, the social dimensions of race are more complex than Census criteria.
The 2000 U. S. census states that racial categories "generally reflect a social definition of race recognized in this country. They do not conform to any biological, anthropological or genetic criteria."The Census question on race lists the categories White or European American, Black or African American, American Indian and Alaska Native, Native Hawaiian or Other Pacific Islander, plus "Some other race", with the respondent having the ability to mark more than one racial and or ethnic category. The Census Bureau defines White people as follows: "White" refers to a person having origins in any of the original peoples of Europe, the Middle East or North Africa, it includes people who indicated their race as "White" or reported entries such as German, Lebanese, Moroccan, or Caucasian. In U. S. census documents, the designation White overlaps, as do all other official racial categories, with the term Hispanic or Latino, introduced in the 1980 census as a category of ethnicity and independent of race.
Hispanic and Latino Americans as a whole make up a racially diverse group and as a whole are the largest minority in the country. The characterization of Middle Eastern and North African Americans as white has been a matter of controversy. In the early 20th century, peoples of Arab descent were sometimes denied entry into the United States because they were characterized as nonwhite. In 1944, the law changed, Middle Eastern and North African peoples were granted white status; the U. S. Census is revisiting the issue, considering creating a separate racial category for Middle Eastern and North African Americans in the 2020 Census. In cases where individuals do not self-identify, the U. S. census parameters for race give each national origin a racial value. Additionally, people who reported Muslim, Zoroastrian, or Caucasian as their "race" in the "Some other race" section, without noting a country of origin, are automatically tallied as White; the US Census considers the write-in response of "Caucasian" or "Aryan" to be a synonym for White in their ancestry code listing.
In the contemporary United States anyone of European descent is considered White. However, many of the non-European ethnic groups classified as White by the U. S. Census, such as Arab Americans, Jewish Americans, Hispanics or Latinos may not identify as, may not be perceived to be, White; the definition of White has changed over the course of American history. Among Europeans, those not considered White at some point in American history include Italians, Spaniards, Swedes and Russians. Early on in the United States, membership in the white race was limited to those of British, Germanic, or Nordic ancestry. David R. Roediger argues that the construction of the white race in the United States was an effort to mentally distance slave owners from slaves; the process of being defined as white by law came about in court disputes over pursuit of citizenship. Critical race theory developed in the 1970s and 1980s, influenced by the language of critical legal studies, which challenged concepts such as objective truth and judicial neutrality, by critical theory.
Academics and activists disillusioned with the outcomes of the Civil Rights Movement pointed out that though African Americans enjoyed legal equality, white Americans continued to hold disproportionate power and still had superior living standards
Religion is a cultural system of designated behaviors and practices, worldviews, sanctified places, ethics, or organizations, that relates humanity to supernatural, transcendental, or spiritual elements. However, there is no scholarly consensus over what constitutes a religion. Different religions may or may not contain various elements ranging from the divine, sacred things, faith, a supernatural being or supernatural beings or "some sort of ultimacy and transcendence that will provide norms and power for the rest of life". Religious practices may include rituals, commemoration or veneration, festivals, trances, funerary services, matrimonial services, prayer, art, public service, or other aspects of human culture. Religions have sacred histories and narratives, which may be preserved in sacred scriptures, symbols and holy places, that aim to give a meaning to life. Religions may contain symbolic stories, which are sometimes said by followers to be true, that have the side purpose of explaining the origin of life, the universe, other things.
Traditionally, faith, in addition to reason, has been considered a source of religious beliefs. There are an estimated 10,000 distinct religions worldwide, but about 84% of the world's population is affiliated with one of the five largest religion groups, namely Christianity, Hinduism, Buddhism or forms of folk religion; the religiously unaffiliated demographic includes those who do not identify with any particular religion and agnostics. While the religiously unaffiliated have grown globally, many of the religiously unaffiliated still have various religious beliefs; the study of religion encompasses a wide variety of academic disciplines, including theology, comparative religion and social scientific studies. Theories of religion offer various explanations for the origins and workings of religion, including the ontological foundations of religious being and belief. Religion is derived from the ultimate origins of which are obscure. One possible interpretation traced to Cicero, connects lego read, i.e. re with lego in the sense of choose, go over again or consider carefully.
The definition of religio by Cicero is cultum deorum, "the proper performance of rites in veneration of the gods." Julius Caesar used religio to mean "obligation of an oath" when discussing captured soldiers making an oath to their captors. The Roman naturalist Pliny the Elder used the term religio on elephants in that they venerate the sun and the moon. Modern scholars such as Tom Harpur and Joseph Campbell favor the derivation from ligare bind, connect from a prefixed re-ligare, i.e. re + ligare or to reconnect, made prominent by St. Augustine, following the interpretation given by Lactantius in Divinae institutiones, IV, 28; the medieval usage alternates with order in designating bonded communities like those of monastic orders: "we hear of the'religion' of the Golden Fleece, of a knight'of the religion of Avys'". In the ancient and medieval world, the etymological Latin root religio was understood as an individual virtue of worship in mundane contexts. In general, religio referred to broad social obligations towards anything including family, neighbors and towards God.
Religio was most used by the ancient Romans not in the context of a relation towards gods, but as a range of general emotions such as hesitation, anxiety, fear. The term was closely related to other terms like scrupulus which meant "very precisely" and some Roman authors related the term superstitio, which meant too much fear or anxiety or shame, to religio at times; when religio came into English around the 1200s as religion, it took the meaning of "life bound by monastic vows" or monastic orders. The compartmentalized concept of religion, where religious things were separated from worldly things, was not used before the 1500s; the concept of religion was first used in the 1500s to distinguish the domain of the church and the domain of civil authorities. In the ancient Greece, the Greek term threskeia was loosely translated into Latin as religio in late antiquity; the term was sparsely used in classical Greece but became more used in the writings of Josephus in the first century CE. It was used in mundane contexts and could mean multiple things from respectful fear to excessive or harmfully distracting practices of others.
It was contrasted with the Greek word deisidaimonia which meant too much fear. The modern concept of religion, as an abstraction that entails distinct sets of beliefs or doctrines, is a recent invention in the English language; such usage began with texts from the 17th century due to events such the splitting of Christendom during the Protestant Reformation and globalization in the age of exploration, which involved contact with numerous foreign cultures with non-European languages. Some argue that regardless of its definition, it is not appropriate to apply the term religion to non-Western cultures. Others argue that using religion on non-western cultures distorts what people believe; the concept of religion was formed in the 16th and 17th centuries, despite the fact that ancient sacred texts like the Bible, the Quran, others did not have a word or a concept of religion in the original languages and neither did the peopl
Chinese Americans are Americans who are descendants of Chinese ancestry, which includes American-born Chinese persons. Chinese Americans constitute one group of overseas Chinese and a subgroup of East Asian Americans, a further subgroup of Asian Americans. Many Chinese Americans are immigrants along with their descendants from mainland China, Hong Kong, Taiwan, as well as from other regions that include large populations of the Chinese diaspora Southeast Asia and some Western countries like Canada, the United Kingdom, New Zealand and France; the Chinese American community is the largest overseas Chinese community outside Asia. It is the third largest community in the Chinese diaspora, behind the Chinese communities in Thailand and Malaysia; the 2016 Community Survey of the US Census estimates a population of Chinese Americans of one or more races to be 5,081,682. The Chinese American community comprises the largest ethnic group of Asian Americans, comprising 25.9% of the Asian American population as of 2010.
Americans of Chinese descent, including those with partial Chinese ancestry constitute 1.5% of the total U. S. population as of 2017. According to the 2010 census, the Chinese American population numbered 3.8 million. In 2010, half of Chinese-born people living in the United States resided in the states of California and New York; the first Chinese immigrants arrived in 1820, according to U. S. government records. 325 men are known to have arrived before the 1849 California Gold Rush, which drew the first significant number of laborers from China who mined for gold and performed menial labor. There were 25,000 immigrants by 1852, 105,465 by 1880, most of whom lived on the West Coast, they formed over a tenth of California's population. Nearly all of the early immigrants were young males with low educational levels from six districts in Guangdong Province. In the 1850s, Chinese workers migrated to the United States, first to work in the gold mines, but to take agricultural jobs, factory work in the garment industry.
Chinese immigrants were instrumental in building railroads in the American west, as Chinese laborers grew successful in the United States, a number of them became entrepreneurs in their own right. As the numbers of Chinese laborers increased, so did the strength of anti-Chinese attitude among other workers in the American economy; this resulted in legislation that aimed to limit future immigration of Chinese workers to the United States, threatened to sour diplomatic relations between the United States and China. The Chinese laborers worked out well and thousands more were recruited until the railroad's completion in 1869. Chinese labor provided the massive workforce needed to build the majority of the Central Pacific's difficult route through the Sierra Nevada mountains and across Nevada. American objections to Chinese immigration took many forms, stemmed from economic and cultural tensions, as well as ethnic discrimination. Most Chinese laborers who came to the United States did so in order to send money back to China to support their families there.
At the same time, they had to repay loans to the Chinese merchants who paid their passage to America. These financial pressures left them little choice. Non-Chinese laborers required much higher wages to support their wives and children in the United States, generally had a stronger political standing to bargain for higher wages. Therefore, many of the non-Chinese workers in the United States came to resent the Chinese laborers, who might squeeze them out of their jobs. Furthermore, as with most immigrant communities, many Chinese settled in their own neighborhoods, tales spread of Chinatowns as places where large numbers of Chinese men congregated to visit prostitutes, smoke opium, or gamble; some advocates of anti-Chinese legislation therefore argued that admitting Chinese into the United States lowered the cultural and moral standards of American society. Others used a more overtly racist argument for limiting immigration from East Asia, expressed concern about the integrity of American racial composition.
To address these rising social tensions, from the 1850s through the 1870s the California state government passed a series of measures aimed at Chinese residents, ranging from requiring special licenses for Chinese businesses or workers to preventing naturalization. Because anti-Chinese discrimination and efforts to stop Chinese immigration violated the 1868 Burlingame-Seward Treaty with China, the federal government was able to negate much of this legislation; the Chinese population rose from 2,716 in 1851 to 63,000 by 1871. In the decade 1861-70, 64,301 were recorded as arriving, followed by 123,201 in 1871-80 and 61,711 in 1881-1890. 77% were located in California, with the rest scattered across the West, the South, New England. Most came from Southern China looking for a better life, escaping a high rate of poverty left after the Taiping Rebellion. In 1879, advocates of immigration restriction succeeded in introducing and passing legislation in Congress to limit the number of Chinese arriving to fifteen per ship or vessel.
Republican President Rutherford B. Hayes vetoed the bill because it violated U. S. treaty agreements with China. It was still an important victory for advocates of exclusion. Democrats, led by supporters in the West, advocated for all-out exclusion of Chinese
White privilege is the societal privilege that benefits people whom society identifies as white in some countries, beyond what is experienced by non-white people under the same social, political, or economic circumstances. Academic perspectives such as critical race theory and whiteness studies use the concept to analyze how racism and racialized societies affect the lives of white or white-skinned people. According to Peggy McIntosh, whites in Western societies enjoy advantages that non-whites do not experience, as "an invisible package of unearned assets". White privilege denotes both obvious and less obvious passive advantages that white people may not recognize they have, which distinguishes it from overt bias or prejudice; these include cultural affirmations of one's own worth. The effects can be seen in professional and personal contexts; the concept of white privilege implies the right to assume the universality of one's own experiences, marking others as different or exceptional while perceiving oneself as normal.
Some commentators say that the term uses the concept of "whiteness" as a proxy for class or other social privilege or as a distraction from deeper underlying problems of inequality. Others state that it is not that whiteness is a proxy but that many other social privileges are interconnected with it, requiring complex and careful analysis to identify how whiteness contributes to privilege. Other commentators propose alternative definitions of whiteness and exceptions to or limits of white identity, arguing that the concept of white privilege ignores important differences between white subpopulations and individuals and suggesting that the notion of whiteness cannot be inclusive of all white people, they note the problem of acknowledging the diversity of people of color and ethnicity within these groups. Writers have noted that the "academic-sounding concept of white privilege" sometimes elicits defensiveness and misunderstanding among white people, in part due to how the concept of white privilege was brought into the mainstream spotlight through social media campaigns such as Black Lives Matter.
As an academic concept, only brought into the mainstream, the concept of white privilege is misinterpreted by non-academics. Although the definition of "white privilege" has been somewhat fluid, it is agreed to refer to the implicit or systemic advantages that white people have relative to people who are the objects of racism, it is the flipside of racism and is used in discussions focused on the hidden benefits that white people possess in a society where racism is prevalent and whiteness is considered normal, rather than on the detriments to people who are the objects of racism. As such, most definitions and discussions of the concept use as a starting point McIntosh's metaphor of the "invisible backpack" that white people unconsciously "wear" in a society where racism is prevalent. In his 1935 Black Reconstruction in America, W. E. B. Du Bois introduced the concept of a "psychological wage" for white laborers; this special status, he wrote, divided the labor movement by leading low-wage white workers to feel superior to low-wage black workers.
Du Bois identified white supremacy as a global phenomenon, affecting the social conditions across the world by means of colonialism. For instance, Du Bois wrote: It must be remembered that the white group of laborers, while they received a low wage, were compensated in part by a sort of public and psychological wage, they were given public deference and titles of courtesy. They were admitted with all classes of white people to public functions, public parks, the best schools; the police were drawn from their ranks, the courts, dependent on their votes, treated them with such leniency as to encourage lawlessness. Their vote selected public officials, while this had small effect upon the economic situation, it had great effect upon their personal treatment and the deference shown them. White schoolhouses were the best in the community, conspicuously placed, they cost anywhere from twice to ten times as much per capita as the colored schools; the newspapers specialized on news that flattered the poor whites and utterly ignored the Negro except in crime and ridicule.
In 1965, drawing from that insight, inspired by the civil rights movement, Theodore W. Allen began a 40-year analysis of "white skin privilege", "white race" privilege, "white" privilege in a call he drafted for a "John Brown Commemoration Committee" that urged "White Americans who want government of the people" and "by the people" to "begin by first repudiating their white skin privileges"; the pamphlet, "White Blindspot", containing one essay by Allen and one by historian Noel Ignatiev, was published in the late 1960s. It focused on the struggle against "white skin privilege" and influenced the Students for a Democratic Society and sectors of the New Left. By June 15, 1969, the New York Times was reporting that the National Office of Students for a Democratic Society was calling "for an all-out fight against'white skin privileges'". From 1974 to 1975, Allen extended his analysis to the colonial period, leading to the publication of "Class Struggle and the Origin of Racial Slavery: The Invention of the White Race," which grew into his two-volume "The Invention of the White Race" in 1994 and 199
Professor is an academic rank at universities and other post-secondary education and research institutions in most countries. Professor derives from Latin as a "person who professes" being an expert in arts or sciences, a teacher of the highest rank. In most systems of academic ranks the word "Professor" only refers to the most senior academic position, sometimes informally known as "full professor". In some countries or institutions, the word professor is used in titles of lower ranks such as associate professor and assistant professor; this colloquial usage would be considered incorrect among most other academic communities. However, the unqualified title Professor designated with a capital letter refers to a full professor in English language usage. Professors conduct original research and teach undergraduate and postgraduate courses in their fields of expertise. In universities with graduate schools, professors may mentor and supervise graduate students conducting research for a thesis or dissertation.
In many universities,'full professors' take on senior managerial roles, leading departments, research teams and institutes, filling roles such as president, principal or vice-chancellor. The role of professor may be more public facing than that of more junior staff, professors are expected to be national or international leaders in their field of expertise; the term "professor" was first used in the late 14th century to mean "one who teaches a branch of knowledge". The word comes "...from Old French professeur and directly from Latin professor'person who professes to be an expert in some art or science. As a title, "prefixed to a name, it dates from 1706"; the "hort form prof is recorded from 1838". The term "professor" is used with a different meaning: "ne professing religion; this canting use of the word comes down from the Elizabethan period, but is obsolete in England." A professor is an accomplished and recognized academic. In most Commonwealth nations, as well as northern Europe, the title professor is the highest academic rank at a university.
In the United States and Canada, the title of professor applies to most post-doctoral academics, so a larger percentage are thus designated. In these areas, professors are scholars with doctorate degrees or equivalent qualifications who teach in four-year colleges and universities. An emeritus professor is a title given to selected retired professors with whom the university wishes to continue to be associated due to their stature and ongoing research. Emeritus professors do not receive a salary, but they are given office or lab space, use of libraries, so on; the term professor is used in the titles assistant professor and associate professor, which are not considered professor-level positions in all European countries. In Australia, the title associate professor is used in place of the term reader as used in the United Kingdom and other Commonwealth countries. Beyond holding the proper academic title, universities in many countries give notable artists and foreign dignitaries the title honorary professor if these persons do not have the academic qualifications necessary for professorship and they do not take up professorial duties.
However, such "professors" do not undertake academic work for the granting institution. In general, the title of professor is used for academic positions rather than for those holding it on honorary basis. Professors are qualified experts in their field who perform some or all the following tasks: Managing teaching and publications in their departments. Other roles of professorial tasks depend on the institution, its legacy, protocols and time. For example, professors at research-oriented universities in North America and at European universities, are promoted on the basis of research achievements and external grant-raising success. Many colleges and universities and other institutions of higher learning throughout the world follow a similar hierarchical ranking structure amongst scholars in academia. A professor earns a base salary and a range of benefits. In addition, a professor who undertakes additional roles in their institution earns additional income; some professors earn additional income by moonlighting in other jobs, such as consulting, publishing academic or popular press books, giving speeches, or coaching executives.
Some fields give professors more opportun
A social class is a set of subjectively defined concepts in the social sciences and political theory centered on models of social stratification in which people are grouped into a set of hierarchical social categories, the most common being the upper and lower classes. "Class" is a subject of analysis for sociologists, political scientists and social historians. However, there is not a consensus on a definition of "class" and the term has a wide range of sometimes conflicting meanings. In common parlance, the term "social class" is synonymous with "socio-economic class", defined as "people having the same social, cultural, political or educational status", e.g. "the working class". However, academics distinguish social class and socioeconomic status, with the former referring to one's stable sociocultural background and the latter referring to one's current social and economic situation and being more changeable over time; the precise measurements of what determines social class in society has varied over time.
Karl Marx thought. His simple understanding of classes in modern capitalist society are the proletariat, those who work but do not own the means of production; this contrasts with the view of the sociologist Max Weber, who argued "class" is determined by economic position, in contrast to "social status" or "Stand", determined by social prestige rather than just relations of production. The term "class" is etymologically derived from the Latin classis, used by census takers to categorize citizens by wealth in order to determine military service obligations. In the late 18th century, the term "class" began to replace classifications such as estates and orders as the primary means of organizing society into hierarchical divisions; this corresponded to a general decrease in significance ascribed to hereditary characteristics and increase in the significance of wealth and income as indicators of position in the social hierarchy. Social class and behavior were sometimes laid down in law. For example, permitted mode of dress in sometimes and places was regulated, with sumptuous dressing only for the high ranks of society and aristocracy, whereas sumptuary laws stipulated the dress and jewelry appropriate for a person's social rank and station.
Definitions of social classes reflect a number of sociological perspectives, informed by anthropology, economics and sociology. The major perspectives have been Marxism and structural functionalism; the common stratum model of class divides society into a simple hierarchy of working class, middle class and upper class. Within academia, two broad schools of definitions emerge: those aligned with 20th-century sociological stratum models of class society and those aligned with the 19th-century historical materialist economic models of the Marxists and anarchists. Another distinction can be drawn between analytical concepts of social class, such as the Marxist and Weberian traditions, as well as the more empirical traditions such as socio-economic status approach, which notes the correlation of income and wealth with social outcomes without implying a particular theory of social structure. For Marx, class is a combination of subjective factors. Objectively, a class shares a common relationship to the means of production.
Subjectively, the members will have some perception of their similarity and common interest. Class consciousness is not an awareness of one's own class interest but is a set of shared views regarding how society should be organized culturally and politically; these class relations are reproduced through time. In Marxist theory, the class structure of the capitalist mode of production is characterized by the conflict between two main classes: the bourgeoisie, the capitalists who own the means of production and the much larger proletariat who must sell their own labour power; this is the fundamental economic structure of work and property, a state of inequality, normalized and reproduced through cultural ideology. Marxists explain the history of "civilized" societies in terms of a war of classes between those who control production and those who produce the goods or services in society. In the Marxist view of capitalism, this is a conflict between wage-workers. For Marxists, class antagonism is rooted in the situation that control over social production entails control over the class which produces goods—in capitalism this is the exploitation of workers by the bourgeoisie.
Furthermore, "in countries where modern civilisation has become developed, a new class of petty bourgeois has been formed". "An industrial army of workmen, under the command of a capitalist, like a real army and sergeants who, while the work is being done, command in the name of the capitalist". Marx makes the argument that, as the bourgeoisie reach a point of wealth accumulation, they hold enough power as the dominant class to shape political institutions and society according to their own interests. Marx goes on to claim that the non-elite class, owing to their large numbers, have the power to overthrow the elite and create an equal society. In The Communist Manifesto, Marx himself argued that it was the goal of the proletariat itself to displace the capitalist system with socialism, changing the so
