モンゴルが建国されたのはいつ
At the end of the 17th century, present-day Mongolia became part of the area ruled by the Manchu-led Qing dynasty. During the collapse of the Qing in 1911, Mongolia declared independence but had to struggle until 1921 to firmly establish "de facto" independence and until 1945 to gain international recognition. As a consequence, Mongolia came under strong Soviet influence: in 1924 the Mongolian People's Republic was declared, and Mongolian politics began to follow the same patterns as Soviet politics of the time. After the revolutions of 1989, the Mongolian Revolution of 1990 led to a multi-party system, a new constitution in 1992, and a transition to a market economy.
