The Mongolian People's Revolutionary Party (MPRP) is a political party in Mongolia, founded in 1921. It played a significant role in the country's history, particularly during the socialist period when Mongolia was aligned with the Soviet Union. The MPRP was the ruling party until the democratic revolution in 1990, which led to a multi-party system. After the democratic changes, the MPRP restructured itself and continues to be active in Mongolian politics. It has undergone various transformations and has participated in several elections, advocating for socialist principles while adapting to the modern political landscape of Mongolia.
