Anatolia ( Turkish: Anadolu , in Modern Greek: Ανατολία , from Ἀνατολή , Anatolḗ , pronunciation Anatolía – "east" or "(sun)rise"), sometimes known as Asia Minor ( Turkish: Küçük Asya , in Medieval and Modern Greek: Μικρά Ἀσία , Mīkrá Asía , pronunciation Mikrá Asía – "small Asia"), Asian Turkey , the Anatolian peninsula , or the Anatolian plateau , is the westernmost protrusion of Asia, which makes up the majority of modern-day Turkey. The region is bounded by the Black Sea to the north, the Mediterranean Sea to the south, and the Aegean Sea to the west. The Sea of Marmara forms a connection between the Black and Aegean Seas through the Bosphorus and Dardanelles straits and separates Anatolia from Thrace on the European mainland.
Traditionally, Anatolia is considered to extend in the east to a line between the Gulf of Alexandretta and the Black Sea to the Armenian Highlands (Armenia Major). This region is now named and largely situated in the Eastern Anatolia Region of the far north east of Turkey and converges with the Lesser Caucasus – an area that was incorporated in the Russian Empire region of Transcaucasia in the 19th century.   Thus, traditionally Anatolia is the territory that comprises approximately the western two-thirds of the Asian part of Turkey.
Anatolia is often considered to be synonymous with Asian Turkey, which comprises almost the entire country;  its eastern and southeastern borders are widely taken to be the Turkish borders with neighboring Georgia, Armenia, Azerbaijan, Iran, Iraq, and Syria, in clockwise direction.
The ancient inhabitants of Anatolia spoke the now-extinct Anatolian languages, which were largely replaced by the Greek language starting from classical antiquity and during the Hellenistic, Roman and Byzantine periods. The Turkification of Anatolia began under the Seljuk Empire in the late 11th century and continued under the Ottoman Empire between the early 14th and early 20th centuries. However, various non-Turkic languages continue to be spoken by minorities in Anatolia today, including Kurdish, Assyrian, Armenian, Arabic, Laz, Georgian, and Greek. Ancient peoples in the region included Galatians, Hurrians, Scythians, Assyrians, Medes, Persians, Hattians, Cimmerians, Ionian Greeks, the Mongols and Arabs.
The Anatolian peninsula, also called Asia Minor, is bounded by the Black Sea to the north, the Mediterranean Sea to the south, the Aegean Sea to the west, and the Sea of Marmara to the northwest, which separates Anatolia from Thrace in Europe.
Traditionally, Anatolia is considered to extend in the east to an indefinite line running from the Gulf of Alexandretta to the Black Sea, coterminous with the Anatolian Plateau. This traditional geographical definition is used, for example, in the latest edition of Merriam-Webster's Geographical Dictionary ,  as well as the archeological community.  Under this definition, Anatolia is bounded to the east by the Armenian Highlands, and the Euphrates before that river bends to the southeast to enter Mesopotamia.  To the southeast, it is bounded by the ranges that separate it from the Orontes valley in Syria (region) and the Mesopotamian plain. 
Following the Armenian Genocide and establishment of the Republic of Turkey, the Armenian Highlands (or Western Armenia) were renamed "Eastern Anatolia" (literally The Eastern East ) by the Turkish government,   being effectively co-terminous with Asian Turkey. Turkey's First Geography Congress in 1941 created two regions to the east of the Gulf of Iskenderun-Black Sea line named the Eastern Anatolia Region and the Southeastern Anatolia Region,  the former largely corresponding to the western part of the Armenian Highland, the latter to the northern part of the Mesopotamian plain. This wider definition of Anatolia has gained widespread currency outside of Turkey and has, for instance, been adopted by Encyclopædia Britannica  and other encyclopedic and general reference publications.  Vazken Davidian terms the expanded use of "Anatolia" to apply to territory formerly referred to as Armenia as "an historical imposition", and notes that a growing body of literature is uncomfortable with referring to the Ottoman East as "Eastern Anatolia".
Onomastics and etymology
The oldest known reference to Anatolia – as “Land of the Hatti ” – appears on Mesopotamian cuneiform tablets from the period of the Akkadian Empire (2350–2150 BC). The first recorded name the Greeks used for the Anatolian peninsula, Ἀσία ( Asía),  presumably echoed the name of the Assuwa league in western Anatolia. As the name "Asia" broadened its scope to apply to other areas east of the Mediterranean, Greeks in Late Antiquity came to use the name Μικρὰ Ἀσία ( Mikrá Asía ) or Asia Minor, meaning "Lesser Asia" to refer to present-day Anatolia.
The English-language name Anatolia itself derives from the Greek ἀνατολή ( anatolḗ ) meaning “the East” or more literally “sunrise” (comparable to the Latin-derived terms “ levant ” and “ orient ”).   The precise reference of this term has varied over time, perhaps originally referring to the Aeolian, Ionian and Dorian colonies on the west coast of Asia Minor. In the Byzantine Empire, the Anatolic Theme (Aνατολικόν θέμα) was a theme covering the western and central parts of Turkey's present-day Central Anatolia Region. The modern Turkish form of Anatolia, Anadolu , derives from the Greek name Aνατολή ( Anatolḗ ). The Russian male name Anatoly and the French Anatole share the same linguistic origin.
In English the name of Turkey for ancient Anatolia first appeared c. 1369. It derives from the Medieval Latin Turchia (meaning “Land of the Turks”, Turkish Türkiye ), a name originally used by Europeans to designate those parts of Anatolia controlled by the Seljuk Sultanate of Rum after the Battle of Manzikert (1071).
Human habitation in Anatolia dates back to the Paleolithic.  Neolithic Anatolia has been proposed as the homeland of the Indo-European language family, although linguists tend to favour a later origin in the steppes north of the Black Sea. However, it is clear that the Anatolian languages, the oldest attested branch of Indo-European, have been spoken in Anatolia since at least the 19th century BC.
Ancient Near East (Bronze and Iron Ages)
Hattians and Hurrians
The earliest historical records of Anatolia stem from the southeast of the region and are from the Mesopotamian -based Akkadian Empire during the reign of Sargon of Akkad in the 24th century BC. Scholars generally believe the earliest indigenous populations of Anatolia were the Hattians and Hurrians. The Hattians spoke a language of unclear affiliation, and the Hurrian language belongs to a small family called Hurro-Urartian, all these languages now being extinct; relationships with indigenous languages of the Caucasus have been proposed but are not generally accepted. The region was famous for exporting raw materials, and areas of Hattian - and Hurrian-populated southeast Anatolia were colonised by the Akkadians.
Assyrian Empire (21st–18th centuries BC)
After the fall of the Akkadian Empire in the mid-21st century BC, the Assyrians, who were the northern branch of the Akkadian people, colonised parts of the region between the 21st and mid-18th centuries BC and claimed its resources, notably silver. One of the numerous cuneiform records dated circa 20th century BC, found in Anatolia at the Assyrian colony of Kanesh, uses an advanced system of trading computations and credit lines.
Hittite Kingdom and Empire (17th–12th centuries BC)
Unlike the Akkadians and their descendants, the Assyrians, whose Anatolian possessions were peripheral to their core lands in Mesopotamia, the Hittites were centred at Hattusa (modern Boğazkale) in north-central Anatolia by the 17th century BC. They were speakers of an Indo-European language, the Hittite language, or nesili (the language of Nesa) in Hittite. Attested for the first time in the Assyrian tablets of Nesa around 2000BC, they conquered Hattusa in the 18th century BC, imposing themselves over Hattian- and Hurrian-speaking populations. According to the widely accepted Kurgan theory on the Proto-Indo-European homeland, however, the Hittites (along with the other Indo-European ancient Anatolians) were themselves relatively recent immigrants to Anatolia from the north.
The Hittites adopted the cuneiform script, invented in Mesopotamia. During the Late Bronze Age circa 1650 BC, they created a kingdom, the Hittite New Kingdom, which became an empire in the 14th century BC after the conquest of Kizzuwatna in the south-east and the defeat of the Assuwa league in western Anatolia. The empire reached its height in the 13th century BC, controlling much of Asia Minor, northwestern Syria and northwest upper Mesopotamia. They failed to reach the Anatolian coasts of the Black Sea, however, as a non-Indo-European people, the semi-nomadic pastoralist and tribal Kaskians, had established themselves there, displacing earlier Palaic-speaking Indo-Europeans. Much of the history of the Hittite Empire concerned war with the rival empires of Egypt, Assyria and the Mitanni.
The Egyptians eventually withdrew from the region after failing to gain the upper hand over the Hittites and becoming wary of the power of Assyria, which had destroyed the Mitanni Empire. The Assyrians and Hittites were then left to battle over control of eastern and southern Anatolia and colonial territories in Syria. The Assyrians had better success than the Egyptians, annexing much Hittite (and Hurrian) territory in these regions.
Neo-Hittite kingdoms (c. 1180–700 BC)
After 1180 BC, during the Late Bronze Age collapse, the Hittite empire disintegrated into several independent Syro-Hittite states, subsequent to losing much territory to the Middle Assyrian Empire and being finally overrun by the Phrygians, another Indo-European people who are believed to have migrated from the Balkans. The Phrygian expansion into southeast Anatolia was eventually halted by the Assyrians, who controlled that region.
Arameans encroached over the borders of south central Anatolia in the century or so after the fall of the Hittite empire, and some of the Syro-Hittite states in this region became an amalgam of Hittites and Arameans. These became known as Syro-Hittite states.
In central and western Anatolia, another Indo-European people, the Luwians, came to the fore, circa 2000 BC. Their language was closely related to Hittite. The general consensus amongst scholars is that Luwian was spoken—to a greater or lesser degree—across a large area of western Anatolia, including (possibly) Wilusa ( Troy), the Seha River Land (to be identified with the Hermos and/or Kaikos valley), and the kingdom of Mira-Kuwaliya with its core territory of the Maeander valley. From the 9th century BC, Luwian regions coalesced into a number of states such as Lydia, Caria and Lycia, all of which had Hellenic influence.
Neo-Assyrian Empire (10th–7th centuries BC)
From the 10th to late 7th centuries BC, much of Anatolia (particularly the east, central, and southeastern regions) fell to the Neo-Assyrian Empire, including all of the Syro-Hittite states, Tabal, Kingdom of Commagene, the Cimmerians and Scythians and swathes of Cappadocia.
The Neo-Assyrian empire collapsed due to a bitter series of civil wars followed by a combined attack by Medes, Persians, Scythians and their own Babylonian relations. The last Assyrian city to fall was Harran in southeast Anatolia. This city was the birthplace of the last king of Babylon, the Assyrian Nabonidus and his son and regent Belshazzar. Much of the region then fell to the short-lived Iran-based Median Empire, with the Babylonians and Scythians briefly appropriating some territory.
Cimmerian and Scythian invasions (8th–7th centuries BC)
From the late 8th century BC, a new wave of Indo-European-speaking raiders entered northern and northeast Anatolia: the Cimmerians and Scythians. The Cimmerians overran Phrygia and the Scythians threatened to do the same to Urartu and Lydia, before both were finally checked by the Assyrians.
The north-western coast of Anatolia was inhabited by Greeks of the Achaean / Mycenaean culture from the 20th century BC, related to the Greeks of south eastern Europe and the Aegean. Beginning with the Bronze Age collapse at the end of the 2nd millennium BC, the west coast of Anatolia was settled by Ionian Greeks, usurping the area of the related but earlier Mycenaean Greeks. Over several centuries, numerous Ancient Greek city-states were established on the coasts of Anatolia. Greeks started Western philosophy on the western coast of Anatolia ( Pre-Socratic philosophy).
In classical antiquity, Anatolia was described by Herodotus and later historians as divided into regions named after tribes such as Lydia, Lycia, Caria, Mysia, Bithynia, Phrygia, Galatia, Lycaonia, Pisidia, Paphlagonia, Cilicia, and Cappadocia. By that time, the populations were a mixture of the ancient Anatolian or " Syro-Hittite " substrate and post-Bronze-Age-collapse "Thraco-Phrygian" and more recent Greco-Macedonian incursions.
Anatolia is known as the birthplace of minted coinage (as opposed to unminted coinage, which first appears in Mesopotamia at a much earlier date) as a medium of exchange, some time in the 7th century BC in Lydia. The use of minted coins continued to flourish during the Greek and Roman eras. 
During the 6th century BC, all of Anatolia was conquered by the Persian Achaemenid Empire, the Persians having usurped the Medes as the dominant dynasty in Iran. In 499 BC, the Ionian city-states on the west coast of Anatolia rebelled against Persian rule. The Ionian Revolt, as it became known, though quelled, initiated the Greco-Persian Wars, which ended in a Greek victory in 449 BC, and the Ionian cities regained their independence, alongside the withdrawal of the Persian forces from their European territories.
In 334 BC, the Macedonian Greek king Alexander the Great conquered the peninsula from the Achaemenid Persian Empire.  Alexander's conquest opened up the interior of Asia Minor to Greek settlement and influence.
Following the death of Alexander and the breakup of his empire, Anatolia was ruled by a series of Hellenistic kingdoms, such as the Attalids of Pergamum and the Seleucids, the latter controlling most of Anatolia. A period of peaceful Hellenization followed, such that the local Anatolian languages had been supplanted by Greek by the 1st century BC. In 133 BC the last Attalid king bequeathed his kingdom to the Roman Republic, and western and central Anatolia came under Roman control, but Hellenistic culture remained predominant. Further annexations by Rome, in particular of the Kingdom of Pontus by Pompey, brought all of Anatolia under Roman control, except for the eastern frontier with the Parthian Empire, which remained unstable for centuries, causing a series of wars, culminating in the Roman-Parthian Wars.
Early Christian period
After the division of the Roman Empire, Anatolia became part of the East Roman, or Byzantine Empire. Anatolia was one of the first places where Christianity spread, so that by the 4th century AD, western and central Anatolia were overwhelmingly Christian and Greek-speaking. For the next 600 years, while Imperial possessions in Europe were subjected to barbarian invasions, Anatolia would be the center of the Hellenic world. Byzantine control was challenged by Arab raids starting in the eighth century (see Arab–Byzantine wars), but in the ninth and tenth century a resurgent Byzantine Empire regained its lost territories, including even long lost territory such as Armenia and Syria (ancient Aram).
Islamic rule replacing Byzantium
In the 10 years following the Battle of Manzikert in 1071, the Seljuk Turks from Central Asia migrated over large areas of Anatolia, with particular concentrations around the northwestern rim.  The Turkish language and the Islamic religion were gradually introduced as a result of the Seljuk conquest, and this period marks the start of Anatolia's slow transition from predominantly Christian and Greek-speaking, to predominantly Muslim and Turkish-speaking (although ethnic groups such as Armenians, Greeks, and Assyrians remained numerous and retained Christianity and their native languages). In the following century, the Byzantines managed to reassert their control in western and northern Anatolia. Control of Anatolia was then split between the Byzantine Empire and the Seljuk Sultanate of Rûm, with the Byzantine holdings gradually being reduced.
In 1255, the Mongols swept through eastern and central Anatolia, and would remain until 1335. The Ilkhanate garrison was stationed near Ankara.  After the decline of the Ilkhanate from 1335–1353, the Mongol Empire's legacy in the region was the Uyghur Eretna Dynasty that was overthrown by Kadi Burhan al-Din in 1381. 
By the end of the 14th century, most of Anatolia was controlled by various Anatolian beyliks. Smyrna fell in 1330, and the last Byzantine stronghold in Anatolia, Philadelphia, fell in 1390. The Turkmen Beyliks were under the control of the Mongols, at least nominally, through declining Seljuk sultans.   The Beyliks did not mint coins in the names of their own leaders while they remained under the suzerainty of the Mongol Ilkhanids.  The Osmanli ruler Osman I was the first Turkish ruler who minted coins in his own name in 1320s, for it bears the legend "Minted by Osman son of Ertugul".  Since the minting of coins was a prerogative accorded in Islamic practice only to a sovereign, it can be considered that the Osmanli, or Ottoman Turks, became formally independent from the Mongol Khans. 
Among the Turkish leaders, the Ottomans emerged as great power under Osman I and his son Orhan I. The Anatolian beyliks were successively absorbed into the rising Ottoman Empire during the 15th century. It is not well understood how the Osmanlı, or Ottoman Turks, came to dominate their neighbours, as the history of medieval Anatolia is still little known.  The Ottomans completed the conquest of the peninsula in 1517 with the taking of Halicarnassus (modern Bodrum) from the Knights of Saint John.
With the acceleration of the decline of the Ottoman Empire in the early 19th century, and as a result of the expansionist policies of Czarist Russia in the Caucasus, many Muslim nations and groups in that region, mainly Circassians, Tatars, Azeris, Lezgis, Chechens and several Turkic groups left their homelands and settled in Anatolia. As the Ottoman Empire further shrank in the Balkan regions and then fragmented during the Balkan Wars, much of the non-Christian populations of its former possessions, mainly Balkan Muslims (Bosnian Muslims, Albanians, Turks, Muslim Bulgarians and Greek Muslims such as the Vallahades from Greek Macedonia), were resettled in various parts of Anatolia, mostly in formerly Christian villages throughout Anatolia.
A continuous reverse migration occurred since the early 19th century, when Greeks from Anatolia, Constantinople and Pontus area migrated toward the newly independent Kingdom of Greece, and also towards the United States, southern part of the Russian Empire, Latin America and rest of Europe.
Following the Russo-Persian Treaty of Turkmenchay (1828) and the incorporation of the Eastern Armenia into the Russian Empire, another migration involved the large Armenian population of Anatolia, which recorded significant migration rates from Western Armenia (Eastern Anatolia) toward the Russian Empire, especially toward its newly established Armenian provinces.
Anatolia remained multi-ethnic until the early 20th century (see the rise of nationalism under the Ottoman Empire). During World War I, the Armenian Genocide, the Greek genocide (especially in Pontus), and the Assyrian genocide almost entirely removed the ancient indigenous communities of Armenian, Greek, and Assyrian populations in Anatolia and surrounding regions. Following the Greco-Turkish War of 1919–1922, most remaining ethnic Anatolian Greeks were forced out during the 1923 population exchange between Greece and Turkey. Many more have left Turkey since, leaving fewer than 5,000 Greeks in Anatolia today. Since the foundation of the Republic of Turkey in 1923, Anatolia has been within Turkey, its inhabitants being mainly Turks and Kurds (see demographics of Turkey and history of Turkey).
Anatolia's terrain is structurally complex. A central massif composed of uplifted blocks and downfolded troughs, covered by recent deposits and giving the appearance of a plateau with rough terrain, is wedged between two folded mountain ranges that converge in the east. True lowland is confined to a few narrow coastal strips along the Aegean, Mediterranean, and Black Sea coasts. Flat or gently sloping land is rare and largely confined to the deltas of the Kızıl River, the coastal plains of Çukurova and the valley floors of the Gediz River and the Büyük Menderes River as well as some interior high plains in Anatolia, mainly around Lake Tuz (Salt Lake) and the Konya Basin ( Konya Ovasi ).
Anatolia has a varied range of climates. The central plateau is characterized by a continental climate, with hot summers and cold snowy winters. The south and west coasts enjoy a typical Mediterranean climate, with mild rainy winters, and warm dry summers.  The Black Sea and Marmara coasts have a temperate oceanic climate, with cool foggy summers and much rainfall throughout the year.
There is a diverse number of plant and animal communities.
The mountains and coastal plain of northern Anatolia experiences humid and mild climate. There are temperate broadleaf, mixed and coniferous forests. The central and eastern plateau, with its drier continental climate, has deciduous forests and forest steppes. Western and southern Anatolia, which have a Mediterranean climate, contain Mediterranean forests, woodlands, and scrub ecoregions.
- Euxine-Colchic deciduous forests: These temperate broadleaf and mixed forests extend across northern Anatolia, lying between the mountains of northern Anatolia and the Black Sea. They include the enclaves of temperate rainforest lying along the southeastern coast of the Black Sea in eastern Turkey and Georgia. 
- Northern Anatolian conifer and deciduous forests: These forests occupy the mountains of northern Anatolia, running east and west between the coastal Euxine-Colchic forests and the drier, continental climate forests of central and eastern Anatolia. 
- Central Anatolian deciduous forests: These forests of deciduous oaks and evergreen pines cover the plateau of central Anatolia. 
- Central Anatolian steppe: These dry grasslands cover the drier valleys and surround the saline lakes of central Anatolia, and include halophytic (salt tolerant) plant communities. 
- Eastern Anatolian deciduous forests: This ecoregion occupies the plateau of eastern Anatolia. The drier and more continental climate is beneficial for steppe-forests dominated by deciduous oaks, with areas of shrubland, montane forest, and valley forest. 
- Anatolian conifer and deciduous mixed forests: These forests occupy the western, Mediterranean-climate portion of the Anatolian plateau. Pine forests and mixed pine and oak woodlands and shrublands are predominant. 
- Aegean and Western Turkey sclerophyllous and mixed forests: These Mediterranean-climate forests occupy the coastal lowlands and valleys of western Anatolia bordering the Aegean Sea. The ecoregion has forests of Turkish pine (Pinus brutia) , oak forests and woodlands, and maquis shrubland of Turkish pine and evergreen sclerophyllous trees and shrubs, including Olive (Olea europaea) , Strawberry Tree (Arbutus unedo) , Arbutus andrachne , Kermes Oak ( Quercus coccifera) , and Bay Laurel (Laurus nobilis) . 
- Southern Anatolian montane conifer and deciduous forests: These mountain forests occupy the Mediterranean-climate Taurus Mountains of southern Anatolia. Conifer forests are predominant, chiefly Anatolian black pine ( Pinus nigra) , Cedar of Lebanon ( Cedrus libani) , Taurus fir ( Abies cilicica) , and juniper ( Juniperus foetidissima and J. excelsa) . Broadleaf trees include oaks, hornbeam, and maples. 
- Eastern Mediterranean conifer-sclerophyllous-broadleaf forests: This ecoregion occupies the coastal strip of southern Anatolia between the Taurus Mountains and the Mediterranean Sea. Plant communities include broadleaf sclerophyllous maquis shrublands, forests of Aleppo Pine ( Pinus halepensis ) and Turkish Pine (Pinus brutia) , and dry oak (Quercus spp.) woodlands and steppes. 
Almost 80% of the people currently residing in Anatolia are Turks. Kurds constitute a major community in southeastern Anatolia,  and are the largest ethnic minority. Abkhazians, Albanians, Arabs, Arameans, Armenians, Assyrians, Azerbaijanis, Bosnian Muslims, Circassians, Gagauz, Georgians, Serbs, Greeks, Hemshin, Jews, Laz, Levantines, Pomaks, Zazas and a number of other ethnic groups also live in Anatolia in smaller numbers.
