The dynasty you're referring to is the Yuan Dynasty.
The Yuan Dynasty was indeed the largest dynasty in China under Mongol rule, having been established after Kublai Khan conquered China and declared himself emperor. The Yuan Dynasty lasted from 1271 to 1368 and is notable for its role in unifying China and incorporating various cultures and religions under Mongol governance.
In contrast, the Ming Dynasty followed the Yuan Dynasty and lasted from 1368 to 1644. The Ming Dynasty is known for its stability, trade expansion, cultural flourishing, and building projects, including the reconstruction of the Great Wall of China.
