 Inner Mongols and Khalkha Mongols rarely knew their ancestors past 4 generations and Mongol tribal society was not organized among patrilineal clans contrary to what was commonly though, but included unrelated people at the base unit of organization.The Qing tried but failed to promote the Chinese Neo-Confucian ideology of organizing society along patrimonial clans among the Mongols.For the administration of Mongol regions, a bureau of Mongol affairs was founded, called "Monggol jurgan" in Manchu.
