Arabs, Turks, Persians, Kurds, and Azeris (excluding Azerbaijan) constitute the largest ethnic groups in the region by population. Minorities of the Middle East include Jews, Baloch, Greeks, Assyrians, and other Arameans, Berbers, Circassians (including Kabardians), Copts, Druze, Lurs, Mandaeans, Samaritans, Shabaks, Tats, and Zazas. In the Middle East, there is also a Romani community. European ethnic groups that form a diaspora in the region include Albanians, Bosniaks, Crimean Tatars, Franco-Levantines, and Italo-Levantines. Among other migrant populations are Bengalis as well as other Indians, Chinese, Filipinos, Indonesians, Pakistanis, and Sub-Saharan Africans.
The history of the Middle East dates back to ancient times, with the (geopolitical) importance of the region being recognized for millennia. Several major religions have their origins in the Middle East, including Judaism, Christianity, and Islam; the Baha'i faith, Mandaeism, Unitarian Druze, and numerous other belief systems were also established within the region.
The Middle East generally has a hot, arid climate, with several major rivers providing irrigation to support agriculture in limited areas such as the Nile Delta in Egypt, the Tigris and Euphrates watersheds of Mesopotamia, and most of what is known as the Fertile Crescent.
The term "Middle East" may have originated in the 1850s in the British India Office. However, it became more widely known when American naval strategist Alfred Thayer Mahan used the term in 1902 to "designate the area between Arabia and India". During this time the British and Russian Empires were vying for influence in Central Asia, a rivalry which would become known as The Great Game. Mahan realized not only the strategic importance of the region, but also of its center, the Persian Gulf. He labeled the area surrounding the Persian Gulf as the Middle East, and said that after Egypt's Suez Canal, it was the most important passage for Britain to control in order to keep the Russians from advancing towards British India. Mahan first used the term in his article "The Persian Gulf and International Relations", published in September 1902 in the National Review, a British journal.
