When Kubilai Khan conquered the Southern Song dynasty in China?

Kublai Khan conquered the Southern Song dynasty in China in 1279, effectively ending the era of the Song dynasty and establishing the Yuan dynasty. His victory followed a series of military campaigns that began in the 1250s, culminating in a prolonged siege of the Song stronghold of Hangzhou. This conquest marked a significant expansion of Mongol rule and the unification of China under Kublai Khan’s leadership. The Yuan dynasty would go on to influence Chinese culture and governance for nearly a century.
