According to the most widely held hypothesis of the origin of the Indo-European languages, the Kurgan hypothesis, their common ancestor is thought to have originated on the Pontic-Caspian steppe. The Tocharians were an early Indo-European branch in the Tarim Basin. At the beginning of written history the entire steppe population west of Dzungaria spoke Iranian languages. From about 500 AD the Turkic languages replaced the Iranian languages first on the steppe, and later in the oases north of Iran. Additionally, Hungarian speakers, a branch of the Uralic language family, who previously lived in the steppe in what is now Southern Russia, settled in the Carpathian basin in year 895. Mongolic languages are in Mongolia. In Manchuria one finds Tungusic languages and some others.
