Armenian highlands

The Armenian highlands (Armenian: Հայկական լեռնաշխարհ, romanized: Haykakan leṙnašxarh; also known as the Armenian upland, Armenian plateau, or Armenian tableland) comprise the most central and the highest of the three plateaus that together form the northern sector of West Asia. Clockwise starting from the west, the Armenian highlands are bounded by the Anatolian plateau, the Caucasus, the Kura-Aras lowlands, the Iranian Plateau, and Mesopotamia. The highlands are divided into western and eastern regions, defined by the Ararat Valley where Mount Ararat is located. Western Armenia is nowadays referred to as Eastern Anatolia. On the other hand, Eastern Armenia is part of Lesser Caucasus or Caucasus Minor, which was historically known by some as the Anti-Caucasus, meaning "opposite of the Caucasus".

During the Iron Age, the region was known by variations of the name Ararat (Urartu, Uruatri, Urashtu). Later, the Highlands were known as Armenia Major, a central region to the history of Armenians, and one of the four geopolitical regions associated with Armenians, the other three being Armenia Minor, Sophene, and Commagene. The highlands are primarily defined by the geographical dispersal of its native inhabitants, the Armenians. Prior to the appearance of nominally Armenian people in historical records, historians have hypothesized that the region must have been home to various ethnic groups who became homogenous when the Armenian language came to prominence. The population of the Armenian highlands seems to have had a high level of regional genetic continuity for over 6,000 years. Recent studies have shown that the Armenian people descend from the indigenous people of the Armenian highlands and form a distinct genetic isolate in the region. The region was also inhabited during Antiquity by minorities such as Assyrians, Georgians, Greeks, Jews, and Iranians. During the Middle Ages, Arabs and particularly Turkmens and Kurds settled in large numbers in the Armenian highlands.

The region was administered for most of its known history by Armenian nobility and states, whether it was as part of a fully independent Armenian state, as vassals, or as part of a foreign state. Since the 1040s, the highlands have been under the rule of various Turkic peoples and the Safavid dynasty, with pockets of Armenian autonomy in places such as Artsakh. Much of Eastern Armenia, which had been ruled by the Safavids from the 16th century, became part of the Russian Empire in 1828 and was later incorporated into the Soviet Union, while much of Western Armenia was ruled by the Ottoman Empire and later incorporated into modern Turkey. Today, the region is divided between Armenia, Azerbaijan, Georgia, Iran, and Turkey.

The Armenians of Western Armenia were exterminated during the Armenian genocide (1915–1917), orchestrated by the Committee of Union and Progress as part of their Turkification policies. Today, Eastern Armenia is mainly inhabited by Armenians, Azerbaijanis, and Georgians, while Western Armenia is mainly inhabited by Turks, Kurds, Azerbaijanis, Assyrians, and a small population of Armenians (including crypto-Armenians and Hemshins).
