Aramaic is a group of Semitic languages with a 3,000-year history. It has been the language of administration of empires and the language of divine worship. It is the original language of large sections of the biblical books of Daniel and Ezra, and is the main language of the Talmud. Aramaic was the native language of Jesus (see Aramaic of Jesus). Modern Aramaic is spoken today as a first language by numerous, scattered communities, most significantly by Assyrians, Syriacs, and Chaldeans. The language is considered to be endangered. Christian missionaries brought the language into Persia, India and even China. From the seventh century AD onwards, Aramaic was replaced as the lingua franca of the Middle East by Arabic. However, Aramaic remains a literary and liturgical language among Jews, Mandaeans and some Christians, and is still spoken by small isolated communities throughout its original area of influence. The turbulence of the last two centuries has seen speakers of first-language and literary Aramaic dispersed throughout the world.
