Aramaic was the lingua franca of the ancient Near East, used by empires such as the Neo-Assyrian, Neo-Babylonian, and Achaemenid Empires, and served as a language of religious study in Judaism, Christianity, and Gnosticism.
Arabic began to replace Aramaic in the 7th century AD, particularly following the Islamic conquests.
