Mingghan
The mingghan (Uzbek: Minghan, Halh Mongolian: мянгат, romanized: Myangat) was a social-military unit of 1000 households created by Genghis Khan. From this group could be recruited a regiment of 1000 men. It is part of the ancient method of organization developed by Eurasian nomads based on the decimal system. A tumen, which included 10,000 households and soldiers, was the largest group and it was divided into ten mingghan. A mingghan was made up of 10 jaghuns or 100 arbans. An account cited that once he becomes a guard, a mingghan commander's son has to bring a younger brother and 10 other men to serve with him.
