Explanation:

Kublai Khan marked a remarkable change in the Chinese Government. He was the grandson of "Genghis Khan" and the founder of "Yuan dynasty" in the "13th century".

He was the "1st Mongol" to rule over "China". He took control of the area in such a way that Mongol aristocracy remained supreme. When his father dies, his uncle became the king of Mongol dynasty.

After him, his son and later on Kublai Khan ruled the kingdom. All his brothers ruled the Mongol, Northern and Southern China. They ensured that their family members were given official positions and appointed foreigners like Marco Polo, a Venetian explorer.
