Büdragchaagiyn Dashyondon was a long-time official in the Mongolian People’s Revolutionary Party (MPRP). After serving as director of the MPRP school, Dashyondon assumed the position of deputy head of department of the central committee of the MPRP, a position he retained until the beginning of the democratic transition in 1990. He then became the head of the central committee of the Metropolitan Party. In 1991, he rose to become secretary-general of the central committee of the MPRP, which was the equivalent of the then-defunct position of chairman. He served in this capacity until 1996, when the MPRP lost power.
