Electrical engineering is a professional engineering discipline that deals with the study and application of electricity and electromagnetism. This field first became an identifiable occupation in the half of the 19th century after commercialization of the electric telegraph, the telephone, electric power distribution and use. Subsequently and recording media made electronics part of daily life; the invention of the transistor, the integrated circuit, brought down the cost of electronics to the point they can be used in any household object. Electrical engineering has now divided into a wide range of fields including electronics, digital computers, computer engineering, power engineering, telecommunications, control systems, radio-frequency engineering, signal processing and microelectronics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations such as hardware engineering, power electronics and waves, microwave engineering, electrochemistry, renewable energies, electrical materials science, much more.
See glossary of electrical and electronics engineering. Electrical engineers hold a degree in electrical engineering or electronic engineering. Practising engineers may be members of a professional body; such bodies include the Institute of Electrical and Electronics Engineers and the Institution of Engineering and Technology. Electrical engineers work in a wide range of industries and the skills required are variable; these range from basic circuit theory to the management skills required of a project manager. The tools and equipment that an individual engineer may need are variable, ranging from a simple voltmeter to a top end analyzer to sophisticated design and manufacturing software. Electricity has been a subject of scientific interest since at least the early 17th century. William Gilbert was a prominent early electrical scientist, was the first to draw a clear distinction between magnetism and static electricity, he is credited with establishing the term "electricity". He designed the versorium: a device that detects the presence of statically charged objects.
In 1762 Swedish professor Johan Carl Wilcke invented a device named electrophorus that produced a static electric charge. By 1800 Alessandro Volta had developed the voltaic pile, a forerunner of the electric battery In the 19th century, research into the subject started to intensify. Notable developments in this century include the work of Hans Christian Ørsted who discovered in 1820 that an electric current produces a magnetic field that will deflect a compass needle, of William Sturgeon who, in 1825 invented the electromagnet, of Joseph Henry and Edward Davy who invented the electrical relay in 1835, of Georg Ohm, who in 1827 quantified the relationship between the electric current and potential difference in a conductor, of Michael Faraday, of James Clerk Maxwell, who in 1873 published a unified theory of electricity and magnetism in his treatise Electricity and Magnetism. In 1782 Georges-Louis Le Sage developed and presented in Berlin the world's first form of electric telegraphy, using 24 different wires, one for each letter of the alphabet.
This telegraph connected two rooms. It was an electrostatic telegraph. In 1795, Francisco Salva Campillo proposed an electrostatic telegraph system. Between 1803-1804, he worked on electrical telegraphy and in 1804, he presented his report at the Royal Academy of Natural Sciences and Arts of Barcelona. Salva’s electrolyte telegraph system was innovative though it was influenced by and based upon two new discoveries made in Europe in 1800 – Alessandro Volta’s electric battery for generating an electric current and William Nicholson and Anthony Carlyle’s electrolysis of water. Electrical telegraphy may be considered the first example of electrical engineering. Electrical engineering became a profession in the 19th century. Practitioners had created a global electric telegraph network and the first professional electrical engineering institutions were founded in the UK and USA to support the new discipline. Francis Ronalds created an electric telegraph system in 1816 and documented his vision of how the world could be transformed by electricity.
Over 50 years he joined the new Society of Telegraph Engineers where he was regarded by other members as the first of their cohort. By the end of the 19th century, the world had been forever changed by the rapid communication made possible by the engineering development of land-lines, submarine cables, from about 1890, wireless telegraphy. Practical applications and advances in such fields created an increasing need for standardised units of measure, they led to the international standardization of the units volt, coulomb, ohm and henry. This was achieved at an international conference in Chicago in 1893; the publication of these standards formed the basis of future advances in standardisation in various industries, in many countries, the definitions were recognized in relevant legislation. During these years, the study of electricity was considered to be a subfield of physics since the early electrical technology was considered electromechanical in nature; the Technische Universität Darmstadt founded the world's first department of electrical engineering in 1882.
The first electrical engineering degree program was started at Massachusetts Institute of Technology in the physics department
Russia the Russian Federation, is a transcontinental country in Eastern Europe and North Asia. At 17,125,200 square kilometres, Russia is by far or by a considerable margin the largest country in the world by area, covering more than one-eighth of the Earth's inhabited land area, the ninth most populous, with about 146.77 million people as of 2019, including Crimea. About 77 % of the population live in the European part of the country. Russia's capital, Moscow, is one of the largest cities in the world and the second largest city in Europe. Extending across the entirety of Northern Asia and much of Eastern Europe, Russia spans eleven time zones and incorporates a wide range of environments and landforms. From northwest to southeast, Russia shares land borders with Norway, Estonia, Latvia and Poland, Ukraine, Azerbaijan, China and North Korea, it shares maritime borders with Japan by the Sea of Okhotsk and the U. S. state of Alaska across the Bering Strait. However, Russia recognises two more countries that border it, Abkhazia and South Ossetia, both of which are internationally recognized as parts of Georgia.
The East Slavs emerged as a recognizable group in Europe between the 3rd and 8th centuries AD. Founded and ruled by a Varangian warrior elite and their descendants, the medieval state of Rus arose in the 9th century. In 988 it adopted Orthodox Christianity from the Byzantine Empire, beginning the synthesis of Byzantine and Slavic cultures that defined Russian culture for the next millennium. Rus' disintegrated into a number of smaller states; the Grand Duchy of Moscow reunified the surrounding Russian principalities and achieved independence from the Golden Horde. By the 18th century, the nation had expanded through conquest and exploration to become the Russian Empire, the third largest empire in history, stretching from Poland on the west to Alaska on the east. Following the Russian Revolution, the Russian Soviet Federative Socialist Republic became the largest and leading constituent of the Union of Soviet Socialist Republics, the world's first constitutionally socialist state; the Soviet Union played a decisive role in the Allied victory in World War II, emerged as a recognized superpower and rival to the United States during the Cold War.
The Soviet era saw some of the most significant technological achievements of the 20th century, including the world's first human-made satellite and the launching of the first humans in space. By the end of 1990, the Soviet Union had the world's second largest economy, largest standing military in the world and the largest stockpile of weapons of mass destruction. Following the dissolution of the Soviet Union in 1991, twelve independent republics emerged from the USSR: Russia, Belarus, Uzbekistan, Azerbaijan, Kyrgyzstan, Tajikistan and the Baltic states regained independence: Estonia, Lithuania, it is governed as a federal semi-presidential republic. Russia's economy ranks as the twelfth largest by nominal GDP and sixth largest by purchasing power parity in 2018. Russia's extensive mineral and energy resources are the largest such reserves in the world, making it one of the leading producers of oil and natural gas globally; the country is one of the five recognized nuclear weapons states and possesses the largest stockpile of weapons of mass destruction.
Russia is a great power as well as a regional power and has been characterised as a potential superpower. It is a permanent member of the United Nations Security Council and an active global partner of ASEAN, as well as a member of the Shanghai Cooperation Organisation, the G20, the Council of Europe, the Asia-Pacific Economic Cooperation, the Organization for Security and Co-operation in Europe, the World Trade Organization, as well as being the leading member of the Commonwealth of Independent States, the Collective Security Treaty Organization and one of the five members of the Eurasian Economic Union, along with Armenia, Belarus and Kyrgyzstan; the name Russia is derived from Rus', a medieval state populated by the East Slavs. However, this proper name became more prominent in the history, the country was called by its inhabitants "Русская Земля", which can be translated as "Russian Land" or "Land of Rus'". In order to distinguish this state from other states derived from it, it is denoted as Kievan Rus' by modern historiography.
The name Rus itself comes from the early medieval Rus' people, Swedish merchants and warriors who relocated from across the Baltic Sea and founded a state centered on Novgorod that became Kievan Rus. An old Latin version of the name Rus' was Ruthenia applied to the western and southern regions of Rus' that were adjacent to Catholic Europe; the current name of the country, Россия, comes from the Byzantine Greek designation of the Rus', Ρωσσία Rossía—spelled Ρωσία in Modern Greek. The standard way to refer to citizens of Russia is rossiyane in Russian. There are two Russian words which are commonly
Armenians are an ethnic group native to the Armenian Highlands of Western Asia. Armenians constitute the de facto independent Artsakh. There is a wide-ranging diaspora of around 5 million people of full or partial Armenian ancestry living outside modern Armenia; the largest Armenian populations today exist in Russia, the United States, Georgia, Germany, Lebanon and Syria. With the exceptions of Iran and the former Soviet states, the present-day Armenian diaspora was formed as a result of the Armenian Genocide. Most Armenians adhere to the Armenian Apostolic Church, a non-Chalcedonian church, the world's oldest national church. Christianity began to spread in Armenia soon after Jesus' death, due to the efforts of two of his apostles, St. Thaddeus and St. Bartholomew. In the early 4th century, the Kingdom of Armenia became the first state to adopt Christianity as a state religion. Armenian is an Indo-European language, it has two mutually intelligible and written forms: Eastern Armenian, today spoken in Armenia, Artsakh and the former Soviet republics.
The unique Armenian alphabet was invented in 405 AD by Mesrop Mashtots. The name Armenian has come to internationally designate this group of people, it was first used by neighbouring countries of ancient Armenia. The earliest attestations of the exonym Armenia date around the 6th century BC. In his trilingual Behistun Inscription dated to 517 BC, Darius I the Great of Persia refers to Urashtu as Armina (in Old Persian. In Greek, Αρμένιοι "Armenians" is attested from about the same time the earliest reference being a fragment attributed to Hecataeus of Miletus. Xenophon, a Greek general serving in some of the Persian expeditions, describes many aspects of Armenian village life and hospitality in around 401 BC, he relates that the people spoke a language that to his ear sounded like the language of the Persians. Armenians call themselves Hay; the name has traditionally been derived from Hayk, the legendary patriarch of the Armenians and a great-great-grandson of Noah, according to Moses of Chorene, defeated the Babylonian king Bel in 2492 BC and established his nation in the Ararat region.
It is further postulated that the name Hay comes from one of the two confederated, Hittite vassal states—the Ḫayaša-Azzi. Movses Khorenatsi, the important early medieval Armenian historian, wrote that the word Armenian originated from the name Armenak or Aram; the Armenian Highland is the area surrounding the highest peak of the region. A controversial hypothesis put forward by some scholars, such as T. Gamkrelidze and V. Ivanov, has proposed that the Indo-European homeland was around the Armenian Highland; the modern Armenian language is grouped with Greek and Ancient Macedonian in the Pontic Indo-European subgroup of Indo-European languages by Eric P. Hamp in his 2012 Indo-European family tree, groups. There are two possible explanations, not mutually exclusive, for a common origin of the Armenian and Greek languages. Ancient Greek scholars, such as Herodotus, suggest that the Phrygians of western Anatolia, who spoke an Indo-European language, had made a contribution to the ethnogenesis of the Armenians: "the Armenians were equipped like Phrygians, being Phrygian colonists".
This appears to imply that some Phrygians migrated eastward to Armenia following the destruction of Phrygia by a Cimmerian invasion in the late 7th century BC. Greek scholars believed that the Phrygians had originated in the Balkans, in an area adjoining Macedonia, from where they had emigrated to Anatolia many centuries earlier. In Hamp's view the homeland of the proposed Greco-Armenian subgroup is the northeast coast of the Black Sea and its hinterlands, he assumes that they migrated from there southeast through the Caucasus with the Armenians remaining after Batumi while the pre-Greeks proceeded westwards along the southern coast of the Black Sea. Some genetics studies explain Armenian diversity by several mixtures of Eurasian populations that occurred between ~3,000 and ~2,000 BC, but genetic signals of population mixture cease after ~1,200 BC when Bronze Age civilizations in the Eastern Mediterranean world and violently collapsed. Armenians have since remained isolated and genetic structure within the population developed ~500 years ago when Armenia was divided between the Ottomans and the Safavid Empire in Iran.
In the Bronze Age, several states flourished in the area of Greater Armenia, including the Hittite Empire and Hayasa-Azzi. Soon after Hayasa-Azzi came Arme-Shupria, the Nairi and the Kingdom of Urartu, who successively established their sovereignty over the Armenian Highland; each of the aforementioned nations and tribes participated in the ethnogenesis of the Armenian people. Under Ashurbanipal, the Assyrian empire reached the Caucasus Mountains. Yerevan, the modern capital of Armenia, was founded in 782 BC by king Argishti I; the first geographical entity, called Armenia by neighboring peoples was established in the late 6th century BC u
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
Jesus referred to as Jesus of Nazareth and Jesus Christ, was a first-century Jewish preacher and religious leader. He is the central figure of Christianity, is described as the most influential person in history. Most Christians believe he is the incarnation of God the Son and the awaited Messiah prophesied in the Old Testament. All modern scholars of antiquity agree that Jesus existed although the quest for the historical Jesus has produced little agreement on the historical reliability of the Gospels and on how the Jesus portrayed in the Bible reflects the historical Jesus. Jesus was a Galilean Jew, baptized by John the Baptist and began his own ministry, he preached orally and was referred to as "rabbi". Jesus debated with fellow Jews on how to best follow God, engaged in healings, taught in parables and gathered followers, he was arrested and tried by the Jewish authorities, turned over to the Roman government, crucified on the order of Pontius Pilate, the Roman prefect. After his death, his followers believed he rose from the dead, the community they formed became the early Church.
The birth of Jesus is celebrated annually on December 25th as Christmas. His crucifixion is honored on his resurrection on Easter; the used calendar era "AD", from the Latin anno Domini, the equivalent alternative "CE", are based on the approximate birthdate of Jesus. Christian doctrines include the beliefs that Jesus was conceived by the Holy Spirit, was born of a virgin named Mary, performed miracles, founded the Christian Church, died by crucifixion as a sacrifice to achieve atonement for sin, rose from the dead, ascended into Heaven, from where he will return. Most Christians believe; the Nicene Creed asserts that Jesus will judge the living and the dead either before or after their bodily resurrection, an event tied to the Second Coming of Jesus in Christian eschatology. The great majority of Christians worship Jesus as the incarnation of God the Son, the second of three persons of the Trinity. A minority of Christian denominations reject Trinitarianism, wholly or as non-scriptural. Jesus figures in non-Christian religions and new religious movements.
In Islam, Jesus is considered one of the Messiah. Muslims believe Jesus was a bringer of scripture and was born of a virgin, but was not the son of God; the Quran states. Most Muslims do not believe that he was crucified, but that he was physically raised into Heaven by God. In contrast, Judaism rejects the belief that Jesus was the awaited Messiah, arguing that he did not fulfill Messianic prophecies, was neither divine nor resurrected. A typical Jew in Jesus' time had only one name, sometimes followed by the phrase "son of <father's name>", or the individual's hometown. Thus, in the New Testament, Jesus is referred to as "Jesus of Nazareth". Jesus' neighbors in Nazareth refer to him as "the carpenter, the son of Mary and brother of James and Joses and Judas and Simon", "the carpenter's son", or "Joseph's son". In John, the disciple Philip refers to him as "Jesus son of Joseph from Nazareth"; the name Jesus is derived from the Latin Iesus, a transliteration of the Greek Ἰησοῦς. The Greek form is a rendering of the Hebrew ישוע, a variant of the earlier name יהושע, or in English, "Joshua", meaning "Yah saves".
This was the name of Moses' successor and of a Jewish high priest. The name Yeshua appears to have been in use in Judea at the time of the birth of Jesus; the 1st-century works of historian Flavius Josephus, who wrote in Koine Greek, the same language as that of the New Testament, refer to at least twenty different people with the name Jesus. The etymology of Jesus' name in the context of the New Testament is given as "Yahweh is salvation". Since early Christianity, Christians have referred to Jesus as "Jesus Christ"; the word Christ was a office, not a given name. It derives from the Greek Χριστός, a translation of the Hebrew mashiakh meaning "anointed", is transliterated into English as "Messiah". In biblical Judaism, sacred oil was used to anoint certain exceptionally holy people and objects as part of their religious investiture. Christians of the time designated Jesus as "the Christ" because they believed him to be the Messiah, whose arrival is prophesied in the Hebrew Bible and Old Testament.
In postbiblical usage, Christ became viewed as a name—one part of "Jesus Christ". The term "Christian" has been in use since the 1st century; the four canonical gospels are the foremost sources for the message of Jesus. However, other parts of the New Testament include references to key episodes in his life, such as the Last Supper in 1 Corinthians 11:23. Acts of the Apostles refers to the early ministry of its anticipation by John the Baptist. Acts 1:1 -- 11 says more about the Ascension of Jesus. In the undisputed Pauline letters, which were written earlier than the gospels, the words or instructions of Jesus are cited several times; some early Christian groups had separate descriptions of the life and teachings of Jesus that are not included in the New Testament. These include the Gospel of Thomas, Gospel
A mathematician is someone who uses an extensive knowledge of mathematics in his or her work to solve mathematical problems. Mathematics is concerned with numbers, quantity, space and change. One of the earliest known mathematicians was Thales of Miletus, he is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number", it was the Pythagoreans who coined the term "mathematics", with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypatia of Alexandria, she succeeded her father as Librarian at the Great Library and wrote many works on applied mathematics. Because of a political dispute, the Christian community in Alexandria punished her, presuming she was involved, by stripping her naked and scraping off her skin with clamshells.
Science and mathematics in the Islamic world during the Middle Ages followed various models and modes of funding varied based on scholars. It was extensive patronage and strong intellectual policies implemented by specific rulers that allowed scientific knowledge to develop in many areas. Funding for translation of scientific texts in other languages was ongoing throughout the reign of certain caliphs, it turned out that certain scholars became experts in the works they translated and in turn received further support for continuing to develop certain sciences; as these sciences received wider attention from the elite, more scholars were invited and funded to study particular sciences. An example of a translator and mathematician who benefited from this type of support was al-Khawarizmi. A notable feature of many scholars working under Muslim rule in medieval times is that they were polymaths. Examples include the work on optics and astronomy of Ibn al-Haytham; the Renaissance brought an increased emphasis on science to Europe.
During this period of transition from a feudal and ecclesiastical culture to a predominantly secular one, many notable mathematicians had other occupations: Luca Pacioli. As time passed, many mathematicians gravitated towards universities. An emphasis on free thinking and experimentation had begun in Britain's oldest universities beginning in the seventeenth century at Oxford with the scientists Robert Hooke and Robert Boyle, at Cambridge where Isaac Newton was Lucasian Professor of Mathematics & Physics. Moving into the 19th century, the objective of universities all across Europe evolved from teaching the “regurgitation of knowledge” to “encourag productive thinking.” In 1810, Humboldt convinced the King of Prussia to build a university in Berlin based on Friedrich Schleiermacher’s liberal ideas. Thus and laboratories started to evolve. British universities of this period adopted some approaches familiar to the Italian and German universities, but as they enjoyed substantial freedoms and autonomy the changes there had begun with the Age of Enlightenment, the same influences that inspired Humboldt.
The Universities of Oxford and Cambridge emphasized the importance of research, arguably more authentically implementing Humboldt’s idea of a university than German universities, which were subject to state authority. Overall, science became the focus of universities in the 20th centuries. Students could conduct research in seminars or laboratories and began to produce doctoral theses with more scientific content. According to Humboldt, the mission of the University of Berlin was to pursue scientific knowledge; the German university system fostered professional, bureaucratically regulated scientific research performed in well-equipped laboratories, instead of the kind of research done by private and individual scholars in Great Britain and France. In fact, Rüegg asserts that the German system is responsible for the development of the modern research university because it focused on the idea of “freedom of scientific research and study.” Mathematicians cover a breadth of topics within mathematics in their undergraduate education, proceed to specialize in topics of their own choice at the graduate level.
In some universities, a qualifying exam serves to test both the breadth and depth of a student's understanding of mathematics. Mathematicians involved with solving problems with applications in real life are called applied mathematicians. Applied mathematicians are mathematical scientists who, with their specialized knowledge and professional methodology, approach many of the imposing problems presented in related scientific fields. With professional focus on a wide variety of problems, theoretical systems, localized constructs, applied mathematicians work in the study and formulation of mathematical models. Mathematicians and applied mathematicians are considered to be two of the STEM careers; the discipline of applied mathematics concerns
In political and social sciences, communism is the philosophical, social and economic ideology and movement whose ultimate goal is the establishment of the communist society, a socioeconomic order structured upon the common ownership of the means of production and the absence of social classes and the state. Communism includes a variety of schools of thought, which broadly include Marxism and anarchism, as well as the political ideologies grouped around both. All of these share the analysis that the current order of society stems from its economic system, capitalism; the two classes are the working class—who must work to survive and who make up the majority within society—and the capitalist class—a minority who derives profit from employing the working class through private ownership of the means of production. The revolution will put the working class in power and in turn establish social ownership of the means of production, which according to this analysis is the primary element in the transformation of society towards communism.
Critics of communism can be divided into those concerning themselves with the practical aspects of 20th century communist states and those concerning themselves with communist principles and theory. Marxism-Leninism and democratic socialism were the two dominant forms of socialism in the 20th century; the term "communism" was first coined and defined in its modern definition by the French philosopher and writer Victor d'Hupay. In his 1777 book Projet de communauté philosophe, d'Hupay pushes the philosophy of the Enlightenment to principles which he lived up to during most of his life in his bastide of Fuveau; this book can be seen as the cornerstone of communist philosophy as d'Hupay defines this lifestyle as a "commune" and advises to "share all economic and material products between inhabitants of the commune, so that all may benefit from everybody's work". According to Richard Pipes, the idea of a classless, egalitarian society first emerged in Ancient Greece; the 5th-century Mazdak movement in Persia has been described as "communistic" for challenging the enormous privileges of the noble classes and the clergy, for criticizing the institution of private property and for striving to create an egalitarian society.
At one time or another, various small communist communities existed under the inspiration of Scripture. For example, in the medieval Christian Church some monastic communities and religious orders shared their land and their other property. Communist thought has been traced back to the works of the 16th-century English writer Thomas More. In his treatise Utopia, More portrayed a society based on common ownership of property, whose rulers administered it through the application of reason. In the 17th century, communist thought surfaced again in England, where a Puritan religious group known as the "Diggers" advocated the abolition of private ownership of land. In his 1895 Cromwell and Communism, Eduard Bernstein argued that several groups during the English Civil War espoused clear communistic, agrarian ideals and that Oliver Cromwell's attitude towards these groups was at best ambivalent and hostile. Criticism of the idea of private property continued into the Age of Enlightenment of the 18th century through such thinkers as Jean Jacques Rousseau in France.
Following the upheaval of the French Revolution communism emerged as a political doctrine. In the early 19th century, various social reformers founded communities based on common ownership. However, unlike many previous communist communities they replaced the religious emphasis with a rational and philanthropic basis. Notable among them were Robert Owen, who founded New Harmony in Indiana, as well as Charles Fourier, whose followers organized other settlements in the United States such as Brook Farm. In its modern form, communism grew out of the socialist movement in 19th-century Europe; as the Industrial Revolution advanced, socialist critics blamed capitalism for the misery of the proletariat—a new class of urban factory workers who labored under often-hazardous conditions. Foremost among these critics were his associate Friedrich Engels. In 1848, Marx and Engels offered a new definition of communism and popularized the term in their famous pamphlet The Communist Manifesto; the 1917 October Revolution in Russia set the conditions for the rise to state power of Vladimir Lenin's Bolsheviks, the first time any avowedly communist party reached that position.
The revolution transferred power to the All-Russian Congress of Soviets, in which the Bolsheviks had a majority. The event generated a great deal of theoretical debate within the Marxist movement. Marx predicted that socialism and communism would be built upon foundations laid by the most advanced capitalist development. However, Russia was one of the poorest countries in Europe with an enormous illiterate peasantry and a minority of industrial workers. Marx had explicitly stated; the moderate Mensheviks opposed Lenin's Bolshevik plan for socialist revolution before capitalism was more developed. The Bolsheviks' successful rise to power was based upon the slogans such as "Peace and land" which tapp
