The last Mongol Khan was Ligden Khan in the early 17th century. He came into conflicts with the Manchus over the looting of Chinese cities, and also alienated most Mongol tribes. He died in 1634. By 1636 most Inner Mongolian tribes had submitted to the Manchus, who founded the Qing dynasty. The Khalkha eventually submitted to Qing rule in 1691, thus bringing all of today's Mongolia under Manchu rule. After several wars, the Dzungars (western Mongols or Oirats) were virtually annihilated during the Qing conquest of Dzungaria in 1757–1758.
