Role in the Mongolian Revolution of 1990 In late 1989, the Democratic movement garnered strength. In March 1990 the first democratic alliance, called Ardchilsan Kholboo (Mongolian Democratic Union), launched a hunger strike urging that the communist government led by Batmönkh resign.

He didn't say what happened to me in detail. He was never a person to talk much about work. He was a very calm person," his widow said. After retirement In 1990, most of his family
