The Middle East is a transcontinental region centered on Western Asia and Egypt. The corresponding adjective is Middle-Eastern and the derived noun is Middle-Easterner. The term has come into wider usage as a replacement of the term Near East (as opposed to Far East) beginning in the early 20th century. Arabs, Turks, Persians, Azeris and Kurds constitute the largest ethnic groups in the region by population, while Armenians, Assyrians, Circassians, Copts, Greeks, Jews, Somalis, Shabaks, Mandaeans and other ethnic and ethnoreligious groups form significant minorities. 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.
