The Greeks or Hellenes are an ethnic group native to Greece, southern Albania, Turkey, Egypt and, to a lesser extent, other countries surrounding the Mediterranean Sea. They form a significant diaspora, with Greek communities established around the world. Greek colonies and communities have been established on the shores of the Mediterranean Sea and Black Sea, but the Greek people have always been centered on the Aegean and Ionian seas, where the Greek language has been spoken since the Bronze Age; until the early 20th century, Greeks were distributed between the Greek peninsula, the western coast of Asia Minor, the Black Sea coast, Cappadocia in central Anatolia, the Balkans and Constantinople. Many of these regions coincided to a large extent with the borders of the Byzantine Empire of the late 11th century and the Eastern Mediterranean areas of ancient Greek colonization; the cultural centers of the Greeks have included Athens, Alexandria and Constantinople at various periods. Most ethnic Greeks live nowadays within the borders of Cyprus.
The Greek genocide and population exchange between Greece and Turkey nearly ended the three millennia-old Greek presence in Asia Minor. Other longstanding Greek populations can be found from southern Italy to the Caucasus and southern Russia and Ukraine and in the Greek diaspora communities in a number of other countries. Today, most Greeks are registered as members of the Greek Orthodox Church. Greeks have influenced and contributed to culture, exploration, philosophy, architecture, mathematics and technology, business and sports, both and contemporarily; the Greeks speak the Greek language, which forms its own unique branch within the Indo-European family of languages, the Hellenic. They are part of a group of classical ethnicities, described by Anthony D. Smith as an "archetypal diaspora people"; the Proto-Greeks arrived at the area now called Greece, in the southern tip of the Balkan peninsula, at the end of the 3rd millennium BC. The sequence of migrations into the Greek mainland during the 2nd millennium BC has to be reconstructed on the basis of the ancient Greek dialects, as they presented themselves centuries and are therefore subject to some uncertainties.
There were at least two migrations, the first being the Ionians and Aeolians, which resulted in Mycenaean Greece by the 16th century BC, the second, the Dorian invasion, around the 11th century BC, displacing the Arcadocypriot dialects, which descended from the Mycenaean period. Both migrations occur at incisive periods, the Mycenaean at the transition to the Late Bronze Age and the Doric at the Bronze Age collapse. An alternative hypothesis has been put forth by linguist Vladimir Georgiev, who places Proto-Greek speakers in northwestern Greece by the Early Helladic period, i.e. towards the end of the European Neolithic. Linguists Russell Gray and Quentin Atkinson in a 2003 paper using computational methods on Swadesh lists have arrived at a somewhat earlier estimate, around 5000 BC for Greco-Armenian split and the emergence of Greek as a separate linguistic lineage around 4000 BC. In c. 1600 BC, the Mycenaean Greeks borrowed from the Minoan civilization its syllabic writing system and developed their own syllabic script known as Linear B, providing the first and oldest written evidence of Greek.
The Mycenaeans penetrated the Aegean Sea and, by the 15th century BC, had reached Rhodes, Crete and the shores of Asia Minor. Around 1200 BC, the Dorians, another Greek-speaking people, followed from Epirus. Traditionally, historians have believed that the Dorian invasion caused the collapse of the Mycenaean civilization, but it is the main attack was made by seafaring raiders who sailed into the eastern Mediterranean around 1180 BC; the Dorian invasion was followed by a poorly attested period of migrations, appropriately called the Greek Dark Ages, but by 800 BC the landscape of Archaic and Classical Greece was discernible. The Greeks of classical antiquity idealized their Mycenaean ancestors and the Mycenaean period as a glorious era of heroes, closeness of the gods and material wealth; the Homeric Epics were and accepted as part of the Greek past and it was not until the time of Euhemerism that scholars began to question Homer's historicity. As part of the Mycenaean heritage that survived, the names of the gods and goddesses of Mycenaean Greece became major figures of the Olympian Pantheon of antiquity.
The ethnogenesis of the Greek nation is linked to the development of Pan-Hellenism in the 8th century BC. According to some scholars, the foundational event was the Olympic Games in 776 BC, when the idea of a common Hellenism among the Greek tribes was first translated into a shared cultural experience and Hellenism was a matter of common culture; the works of Homer and Hesiod were written in the 8th century BC, becoming the basis of the national religion, ethos and mythology. The Oracle of Apollo at Delphi was established in this period; the classical period of Greek civilization covers a time spanning from the early 5th century BC to the death of Alexander the Great, in 323 BC. It is so named because it set the standards by which Greek civilization would be judged in eras; the Classical period is described as the "Golden Age" of Greek civilization, and
Human Development Index
The Human Development Index is a statistic composite index of life expectancy and per capita income indicators, which are used to rank countries into four tiers of human development. A country scores a higher HDI when the lifespan is higher, the education level is higher, the GNI per capita is higher, it was developed by Pakistani economist Mahbub ul Haq, with help from Gustav Ranis of Yale University and Meghnad Desai of the London School of Economics, was further used to measure a country's development by the United Nations Development Program's Human Development Report Office. The 2010 Human Development Report introduced an Inequality-adjusted Human Development Index. While the simple HDI remains useful, it stated that "the IHDI is the actual level of human development", "the HDI can be viewed as an index of'potential' human development"; the index does not take into account several factors, such as the net wealth per capita or the relative quality of goods in a country. This situation tends to lower the ranking for some of the most advanced countries, such as the G7 members and others.
The index is based on the human development approach, developed by ul Haq framed in terms of whether people are able to "be" and "do" desirable things in life. Examples include—Being: well fed, healthy; the freedom of choice is central—someone choosing to be hungry is quite different from someone, hungry because they cannot afford to buy food, or because the country is in a famine. The origins of the HDI are found in the annual Human Development Reports produced by the Human Development Report Office of the United Nations Development Programme; these were devised and launched by Pakistani economist Mahbub ul Haq in 1990, had the explicit purpose "to shift the focus of development economics from national income accounting to people-centered policies". To produce the Human Development Reports, Mahbub ul Haq formed a group of development economists including Paul Streeten, Frances Stewart, Gustav Ranis, Keith Griffin, Sudhir Anand, Meghnad Desai. Nobel laureate Amartya Sen utilized Haq's work in his own work on human capabilities.
Haq believed that a simple composite measure of human development was needed to convince the public and politicians that they can and should evaluate development not only by economic advances but improvements in human well-being. Published on 4 November 2010, the 2010 Human Development Report calculated the HDI combining three dimensions: A long and healthy life: Life expectancy at birth Education index: Mean years of schooling and Expected years of schooling A decent standard of living: GNI per capita In its 2010 Human Development Report, the UNDP began using a new method of calculating the HDI; the following three indices are used: 1. Life Expectancy Index = LE − 20 85 − 20 LEI is 1 when Life expectancy at birth is 85 and 0 when Life expectancy at birth is 20.2. Education Index = MYSI + EYSI 2 2.1 Mean Years of Schooling Index = MYS 15 Fifteen is the projected maximum of this indicator for 2025. 2.2 Expected Years of Schooling Index = EYS 18 Eighteen is equivalent to achieving a master's degree in most countries.3.
Income Index = ln − ln ln − ln II is 1 when GNI per capita is $75,000 and 0 when GNI per capita is $100. The HDI is the geometric mean of the previous three normalized indices: HDI = LEI ⋅ EI ⋅ II 3. LE: Life expectancy at birth MYS: Mean years of schooling EYS: Expected years of schooling GNIpc: Gross national income at purchasing power parity per capita The HDI combined three dimensions last used in its 2009 Report: Life expectancy at birth, as an index of population health and longevity to HDI Knowledge and education, as measured by the adult literacy rate and the combined primary and tertiary gross enrollment ratio. Standard of living, as indicated by the natural logarithm of gross domestic product per capita at purchasing power parity; this methodology was used by the UNDP until their 2011 report. The formula defining the HDI is promulgated by the United Nations Development Programme. In general, to transform a raw variable, say x, into a unit-free index between 0 and 1 (which allo
The Black Sea is a body of water and marginal sea of the Atlantic Ocean between the Balkans, Eastern Europe, the Caucasus, Western Asia. It is supplied by a number of major rivers, such as the Danube, Southern Bug, Dniester and the Rioni. Many countries drain into the Black Sea, including Austria, Belarus and Herzegovina, Croatia, Czech Republic, Germany, Moldova, Romania, Serbia, Slovenia and Ukraine; the Black Sea has an area of 436,400 km2, a maximum depth of 2,212 m, a volume of 547,000 km3. It is constrained by the Pontic Mountains to the south, Caucasus Mountains to the east, Crimean Mountains to the north, Strandzha to the southwest, Dobrogea Plateau to the northwest, features a wide shelf to the northwest; the longest east–west extent is about 1,175 km. Important cities along the coast include Batumi, Constanța, Istanbul, Novorossiysk, Ordu, Rize, Sevastopol, Sukhumi, Varna and Zonguldak; the Black Sea has a positive water balance. There is a two-way hydrological exchange: the more saline and therefore denser, but warmer, Mediterranean water flows into the Black Sea under its less saline outflow.
This creates a significant anoxic layer well below the surface waters. The Black Sea drains into the Mediterranean Sea, via the Aegean Sea and various straits, is navigable to the Atlantic Ocean; the Bosphorus Strait connects it to the Sea of Marmara, the Strait of the Dardanelles connects that sea to the Aegean Sea region of the Mediterranean. These waters separate the Caucasus and Western Asia; the Black Sea is connected, to the North, to the Sea of Azov by the Strait of Kerch. The water level has varied significantly. Due to these variations in the water level in the basin, the surrounding shelf and associated aprons have sometimes been land. At certain critical water levels it is possible for connections with surrounding water bodies to become established, it is through the most active of these connective routes, the Turkish Straits, that the Black Sea joins the world ocean. When this hydrological link is not present, the Black Sea is an endorheic basin, operating independently of the global ocean system, like the Caspian Sea for example.
The Black Sea water level is high. The Turkish Straits connect the Black Sea with the Aegean Sea, comprise the Bosphorus, the Sea of Marmara and the Dardanelles; the International Hydrographic Organization defines the limits of the Black Sea as follows: On the Southwest. The Northeastern limit of the Sea of Marmara. In the Kertch Strait. A line joining Cape Takil and Cape Panaghia. Current names of the sea are equivalents of the English name "Black Sea", including these given in the countries bordering the sea: Abkhazian: Амшын Еиқәа, IPA: Adyghe: Хы шӏуцӏэ, IPA: Bulgarian: Черно море, IPA: Crimean Tatar: Къара денъиз, Qara deñiz IPA: Georgian: შავი ზღვა, translit.: shavi zghva, IPA: Laz and Mingrelian: უჩა ზუღა, IPA:, or ზუღა, IPA:, "Sea" Romanian: Marea Neagră, pronounced Russian: Чёрное мо́рe, IPA: Turkish: Karadeniz, IPA: Ukrainian: Чорне море, IPA: Such names have not yet been shown conclusively to predate the 13th century, but there are indications that they may be older. In Greece, the historical name "Euxine Sea", which holds a different meaning, is still used: Greek: Éfxeinos Póntos.
The principal Greek name "Póntos Áxeinos" is accepted to be a rendering of Iranian word *axšaina-, compare Avestan axšaēna-, Old Persian axšaina-, Middle Persian axšēn/xašēn, New Persian xašīn, as well as Ossetic œxsīn. The ancient Greeks, most those living to the north of the Black Sea, subsequently adopted the name and altered it to á-xenos. Thereafter, Greek tradition refers to the Black Sea as the "Inhospitable Sea", Πόντος Ἄξεινος Póntos Áxeinos, first attested in Pindar; the name was considered to be "ominous" and was changed into the euphemistic name "Hospitable sea", Εὔξεινος Πόντος Eúxeinos Póntos, for the first time attested in Pindar. This became the used designation for the sea in Greek. In contexts related to mythology, the older form Póntos Áxeinos remained favored, it has been erroneously suggested that the name was derived from the color of the water, or was at least related to climatic conditions. Black or dark in this context, referred to a system in which colors represent the cardinal points of the known world.
Black or dark represented the north. The symbolism based on cardinal points was used in multiple occasions and is therefore attested. For example, the "Red Sea", a body of water reported since the time of Herodotus in fact designated the Indian Ocean, together with bodies of water now known as the Persian Gulf and the Red Sea. According to the same explanation and reasoning, it is therefore considered to be impossible
The Caucasus Mountains are a mountain system at the intersection of Europe and Asia. Stretching between the Black Sea and the Caspian Sea, it surrounds the eponymous Caucasus region and is home to Mount Elbrus, the highest peak in Europe; the Caucasus Mountains include Lesser Caucasus in the south. The Greater Caucasus runs west-northwest to east-southeast, from the Caucasian Natural Reserve in the vicinity of Sochi on the northeastern shore of the Black Sea nearly to Baku on the Caspian Sea; the Lesser Caucasus runs parallel to the Greater about 100 km south. The Greater and Lesser Caucasus ranges are connected by the Likhi Range, to the west and east of the Likhi Range lie the Colchis Plain and the Kur-Araz Lowland; the Meskheti Range is a part of the Lesser Caucasus system. In the southeast the Aras River separates the Lesser Caucasus from the Talysh Mountains which straddle the border of southeastern Azerbaijan and Iran; the Lesser Caucasus and the Armenian Highland constitute the Transcaucasian Highland, which at their western end converge with the highland plateau of Eastern Anatolia in the far north east of Turkey.
The highest peak in the Caucasus range is Mount Elbrus in the Greater Caucasus, which rises to a height of 5,642 metres above sea level. Mountains near Sochi hosted part of the 2014 Winter Olympics. Geologically, the Caucasus Mountains belong to a system that extends from southeastern Europe into Asia; the Greater Caucasus Mountains are composed of Cretaceous and Jurassic rocks with the Paleozoic and Precambrian rocks in the higher regions. Some volcanic formations are found throughout the range. On the other hand, the Lesser Caucasus Mountains are formed predominantly of the Paleogene rocks with a much smaller portion of the Jurassic and Cretaceous rocks; the evolution of the Caucasus began from the Late Triassic to the Late Jurassic during the Cimmerian orogeny at the active margin of the Tethys Ocean while the uplift of the Greater Caucasus is dated to the Miocene during the Alpine orogeny. The Caucasus Mountains formed as the result of a tectonic plate collision between the Arabian plate moving northwards with respect to the Eurasian plate.
As the Tethys Sea was closed and the Arabian Plate collided with the Iranian Plate and was pushed against it and with the clockwise movement of the Eurasian Plate towards the Iranian Plate and their final collision, the Iranian Plate was pressed against the Eurasian Plate. As this happened, the entire rocks, deposited in this basin from the Jurassic to the Miocene were folded to form the Greater Caucasus Mountains; this collision caused the uplift and the Cenozoic volcanic activity in the Lesser Caucasus Mountains. The entire region is subjected to strong earthquakes from this activity. While the Greater Caucasus Mountains have a folded sedimentary structure, the Lesser Caucasus Mountains are of volcanic origin; the Javakheti Volcanic Plateau in Georgia and the surrounding volcanic ranges which extend well into central Armenia are some of the youngest features of the region. Only was the Caucasus a scene for intense volcanic activity: the Armenian highland was flooded by calc-alkaline basalts and andesites in the Pliocene and the highest summits of the Caucasus, the Elbrus, the Kazbek, formed as Pleistocene-Pliocene volcanoes.
The Kazbek is no longer active, but the Elbrus erupted in postglacial times and fumarole activity is registered near its summit. Contemporary seismic activity is a prominent feature of the region, reflecting active faulting and crustal shortening. Clusters of seismicity occur in northern Armenia. Many devastating earthquakes have been documented in historical times, including the Spitak earthquake in December 1988 which destroyed the Gyumri-Vanadzor region of Armenia. Europe's highest mountain is Mount Elbrus 5,642 m in the Caucasus Mountains. Elbrus is 832 m higher than the highest peak in the Alps and western Europe at 4,810 m; the crest of the Caucasus Mountains is taken to define the continental divide between Asia and Europe for the region between the Black and Caspian Seas. The table below lists some of the highest peaks of the Caucasus. With the exception of Shkhara, the heights are taken from Soviet 1:50,000 mapping; the list includes all mountains over 4,500 m height with 300 m prominence.
Mount Ararat in Turkey is just south of the lesser Caucasus. The climate of the Caucasus varies both vertically and horizontally. Temperature decreases as elevation rises. Average annual temperature in Sukhumi, Abkhazia at sea level is 15 °C while on the slopes of Mt. Kazbek at an elevation of 3,700 metres, average annual temperature falls to−6.1 °C. The northern slopes of the Greater Caucasus Mountain Range are 3 °C colder than the southern slopes; the highlands of the Lesser Caucasus Mountains in Armenia and Georgia are marked by sharp temperature contrasts between the summer and winter months due to a more continental climate. Precipitation increases from east to west in most areas. Elevation plays an important role in the Caucasus and mountains receive higher amounts of precipitation than low-lying areas; the northeastern regions and the southern portions of the Lesser Caucasus Mountains are the driest. The absolute minimum annual precipitation is 250 mm in the northeastern Caspian Depression.
Western parts of the Caucasus Mountains are marked by high amounts of precipitation. The southern slopes of the Greater Caucasus Mountain Range receive higher amounts of precipitation than the northern slope
An ethnic group or an ethnicity, is a category of people who identify with each other based on similarities such as common ancestry, history, culture or nation. Ethnicity is an inherited status based on the society in which one lives. Membership of an ethnic group tends to be defined by a shared cultural heritage, origin myth, homeland, language or dialect, symbolic systems such as religion and ritual, dressing style, art or physical appearance. Ethnic groups, derived from the same historical founder population continue to speak related languages and share a similar gene pool. By way of language shift, acculturation and religious conversion, it is sometimes possible for individuals or groups to leave one ethnic group and become part of another. Ethnicity is used synonymously with terms such as nation or people. In English, it can have the connotation of something exotic related to cultures of more recent immigrants, who arrived after the dominant population of an area was established; the largest ethnic groups in modern times comprise hundreds of millions of individuals, while the smallest are limited to a few dozen individuals.
Larger ethnic groups may be subdivided into smaller sub-groups known variously as tribes or clans, which over time may become separate ethnic groups themselves due to endogamy or physical isolation from the parent group. Conversely separate ethnicities can merge to form a pan-ethnicity and may merge into one single ethnicity. Whether through division or amalgamation, the formation of a separate ethnic identity is referred to as ethnogenesis; the term ethnic is derived from the Greek word ἔθνος ethnos. The inherited English language term for this concept is folk, used alongside the latinate people since the late Middle English period. In Early Modern English and until the mid-19th century, ethnic was used to mean heathen or pagan, as the Septuagint used ta ethne to translate the Hebrew goyim "the nations, non-Hebrews, non-Jews"; the Greek term in early antiquity could refer to any large group, a host of men, a band of comrades as well as a swarm or flock of animals. In Classical Greek, the term took on a meaning comparable to the concept now expressed by "ethnic group" translated as "nation, people".
In the 19th century, the term came to be used in the sense of "peculiar to a race, people or nation", in a return to the original Greek meaning. The sense of "different cultural groups", in American English "racial, cultural or national minority group" arises in the 1930s to 1940s, serving as a replacement of the term race which had earlier taken this sense but was now becoming deprecated due to its association with ideological racism; the abstract ethnicity had been used for "paganism" in the 18th century, but now came to express the meaning of an "ethnic character". The term ethnic group was first recorded in 1935 and entered the Oxford English Dictionary in 1972. Depending on the context, used, the term nationality may either be used synonymously with ethnicity, or synonymously with citizenship; the process that results in the emergence of an ethnicity is called ethnogenesis, a term in use in ethnological literature since about 1950. Depending on which source of group identity is emphasized to define membership, the following types of groups can be identified: Ethno-linguistic, emphasizing shared language, dialect – example: French Canadians Ethno-national, emphasizing a shared polity or sense of national identity – example: Armenians Ethno-racial, emphasizing shared physical appearance based on genetic origins – example: African Americans Ethno-regional, emphasizing a distinct local sense of belonging stemming from relative geographic isolation – example: South Islanders Ethno-religious, emphasizing shared affiliation with a particular religion, denomination or sect – example: JewsIn many cases – for instance, the sense of Jewish peoplehood – more than one aspect determines membership.
Ethnography begins in classical antiquity. The Greeks at this time did not describe foreign nations but had developed a concept of their own "ethnicity", which they grouped under the name of Hellenes. Herodotus gave a famous account of what defined Greek ethnic identity in his day, enumerating shared descent, shared language shared sanctuaries and sacrifices shared customs. Whether ethnicity qualifies as a cultural universal is to some extent dependent on the exact definition used. According to "Challenges of Measuring an Ethnic World: Science and reality", in Challenges of Measuring an Ethnic World: Science and Reality: Proceedings of the Joint Canada-United States Conference on the Measurement of Ethni
The Ottoman Empire known in Western Europe as the Turkish Empire or Turkey, was a state that controlled much of Southeast Europe, Western Asia and North Africa between the 14th and early 20th centuries. It was founded at the end of the 13th century in northwestern Anatolia in the town of Söğüt by the Oghuz Turkish tribal leader Osman I. After 1354, the Ottomans crossed into Europe, with the conquest of the Balkans, the Ottoman beylik was transformed into a transcontinental empire; the Ottomans ended the Byzantine Empire with the 1453 conquest of Constantinople by Mehmed the Conqueror. During the 16th and 17th centuries, at the height of its power under the reign of Suleiman the Magnificent, the Ottoman Empire was a multinational, multilingual empire controlling most of Southeast Europe, parts of Central Europe, Western Asia, parts of Eastern Europe and the Caucasus, North Africa and the Horn of Africa. At the beginning of the 17th century, the empire contained numerous vassal states; some of these were absorbed into the Ottoman Empire, while others were granted various types of autonomy during the course of centuries.
With Constantinople as its capital and control of lands around the Mediterranean basin, the Ottoman Empire was at the centre of interactions between the Eastern and Western worlds for six centuries. While the empire was once thought to have entered a period of decline following the death of Suleiman the Magnificent, this view is no longer supported by the majority of academic historians; the empire continued to maintain a flexible and strong economy and military throughout the 17th and much of the 18th century. However, during a long period of peace from 1740 to 1768, the Ottoman military system fell behind that of their European rivals, the Habsburg and Russian empires; the Ottomans suffered severe military defeats in the late 18th and early 19th centuries, which prompted them to initiate a comprehensive process of reform and modernisation known as the Tanzimat. Thus, over the course of the 19th century, the Ottoman state became vastly more powerful and organised, despite suffering further territorial losses in the Balkans, where a number of new states emerged.
The empire allied with Germany in the early 20th century, hoping to escape from the diplomatic isolation which had contributed to its recent territorial losses, thus joined World War I on the side of the Central Powers. While the Empire was able to hold its own during the conflict, it was struggling with internal dissent with the Arab Revolt in its Arabian holdings. During this time, atrocities were committed by the Young Turk government against the Armenians and Pontic Greeks; the Empire's defeat and the occupation of part of its territory by the Allied Powers in the aftermath of World War I resulted in its partitioning and the loss of its Middle Eastern territories, which were divided between the United Kingdom and France. The successful Turkish War of Independence against the occupying Allies led to the emergence of the Republic of Turkey in the Anatolian heartland and the abolition of the Ottoman monarchy; the word Ottoman is a historical anglicisation of the name of Osman I, the founder of the Empire and of the ruling House of Osman.
Osman's name in turn was the Turkish form of the Arabic name ʿUthmān. In Ottoman Turkish, the empire was referred to as Devlet-i ʿAlīye-yi ʿOsmānīye, or alternatively ʿOsmānlı Devleti. In Modern Turkish, it is known as Osmanlı Devleti; the Turkish word for "Ottoman" referred to the tribal followers of Osman in the fourteenth century, subsequently came to be used to refer to the empire's military-administrative elite. In contrast, the term "Turk" was used to refer to the Anatolian peasant and tribal population, was seen as a disparaging term when applied to urban, educated individuals. In the early modern period, an educated urban-dwelling Turkish-speaker, not a member of the military-administrative class would refer to himself neither as an Osmanlı nor as a Türk, but rather as a Rūmī, or "Roman", meaning an inhabitant of the territory of the former Byzantine Empire in the Balkans and Anatolia; the term Rūmī was used to refer to Turkish-speakers by the other Muslim peoples of the empire and beyond.
In Western Europe, the two names "Ottoman Empire" and "Turkey" were used interchangeably, with "Turkey" being favoured both in formal and informal situations. This dichotomy was ended in 1920–23, when the newly established Ankara-based Turkish government chose Turkey as the sole official name. Most scholarly historians avoid the terms "Turkey", "Turks", "Turkish" when referring to the Ottomans, due to the empire's multinational character; as the Seljuk Sultanate of Rum declined in the 13th century, Anatolia was divided into a patchwork of independent Turkish principalities known as the Anatolian Beyliks. One of these beyliks, in the region of Bithynia on the frontier of the Byzantine Empire, was led by the Turkish tribal leader Osman I, a figure of obscure origins from whom the name Ottoman is derived. Osman's early followers consisted both of Turkish tribal groups and Byzantine renegades, many but not all converts to Islam. Osman extended the control of his principality by conquering Byzantine towns along the Sakarya River.
It is not well understood how the early Ottomans came to dominate their
Ankara known as Ancyra and Angora, is the capital of Turkey. With a population of 4,587,558 in the urban center and 5,150,072 in its province, it is Turkey's second largest city after Istanbul, having outranked İzmir in the 20th century. On 23 April 1920 the Grand National Assembly of Turkey was established in Ankara, which became the headquarters of Atatürk and the Turkish National Movement during the Turkish War of Independence. Ankara became the new Turkish capital upon the establishment of the Republic on 29 October 1923, succeeding in this role the former Turkish capital Istanbul following the fall of the Ottoman Empire; the government is a prominent employer, but Ankara is an important commercial and industrial city, located at the center of Turkey's road and railway networks. The city gave its name to the Angora wool shorn from Angora rabbits, the long-haired Angora goat, the Angora cat; the area is known for its pears and muscat grapes. Although situated in one of the driest places of Turkey and surrounded by steppe vegetation except for the forested areas on the southern periphery, Ankara can be considered a green city in terms of green areas per inhabitant, at 72 square metres per head.
Ankara is a old city with various Hittite, Hellenistic, Roman and Ottoman archaeological sites. The historical center of town is a rocky hill rising 150 m over the left bank of the Ankara Çayı, a tributary of the Sakarya River, the classical Sangarius; the hill remains crowned by the ruins of the old citadel. Although few of its outworks have survived, there are well-preserved examples of Roman and Ottoman architecture throughout the city, the most remarkable being the 20 BC Temple of Augustus and Rome that boasts the Monumentum Ancyranum, the inscription recording the Res Gestae Divi Augusti; the orthography of the name Ankara has varied over the ages. It has been identified with the Hittite cult center Ankuwaš, although this remains a matter of debate. In classical antiquity and during the medieval period, the city was known as Ánkyra in Greek and Ancyra in Latin. Following its annexation by the Seljuk Turks in 1073, the city became known in many European languages as Angora; the form "Angora" is preserved in the names of breeds of many different kinds of animals, in the names of several locations in the US.
Ankara has a hot-summer Mediterranean climate which borders a hot summer Mediterranean continental climate. Under the Trewartha climate classification, Ankara has a middle latitude steppe climate. Due to its elevation and inland location, Ankara has cold, somewhat snowy winters and hot, dry summers. Rainfall occurs during the spring and autumn. Ankara lies in USDA Hardiness zone 7b, its annual average precipitation is low at 400 millimeters precipitation can be observed throughout the year. Monthly mean temperatures range from 0.3 °C in January to 23.5 °C in July, with an annual mean of 12.02 °C. Ankara had a population of 75,000 in 1927. In 2013, Ankara Province had a population of 5,045,083; when Ankara became the capital of the Republic of Turkey in 1923, it was designated as a planned city for 500,000 future inhabitants. During the 1920s, 1930s and 1940s, the city grew in a planned and orderly pace. However, from the 1950s onward, the city grew much faster than envisioned, because unemployment and poverty forced people to migrate from the countryside into the city in order to seek a better standard of living.
As a result, many illegal houses called gecekondu were built around the city, causing the unplanned and uncontrolled urban landscape of Ankara, as not enough planned housing could be built fast enough. Although precariously built, the vast majority of them have electricity, running water and modern household amenities. Many of these gecekondus have been replaced by huge public housing projects in the form of tower blocks such as Elvankent, Eryaman and Güzelkent. Although many gecekondus still remain, they too are being replaced by mass housing compounds, as empty land plots in the city of Ankara for new construction projects are becoming impossible to find; the region's history can be traced back to the Bronze Age Hattic civilization, succeeded in the 2nd millennium BC by the Hittites, in the 10th century BC by the Phrygians, by the Lydians, Greeks, Romans and Turks. The oldest settlements in and around the city center of Ankara belonged to the Hattic civilization which existed during the Bronze Age and was absorbed c.
2000–1700 BC by the Indo-European Hittites. The city grew in size and importance under the Phrygians starting around 1000 BC, experienced a large expansion following the mass migration from Gordion, after an earthquake which damaged that city around that time. In Phrygian tradition, King Midas was venerated as the founder of Ancyra, but Pausanias mentions that the city was far older, which accords with present archaeological knowledge. Phrygian rule was succeeded first by Lydian and by Persian rule, though the Phrygian character of the peasantry remained, as evidenced by the gravestones of the much Roman period. Persian sovereignty lasted until the Persians' defeat at the
