It was the Qing Dynasty that conquered and ruled Mongolia for 200 years.
The Mongols, led by Kublai Khan, conquered all of China in the 13th century, integrating Mongol territories into the vast Chinese empire. Similarly, the Manchus conquered China, fully incorporating their homeland and people into the empire. They went on to establish themselves as the ruling class of China's final imperial dynasty.
