Zheng He was a Chinese explorer, mariner, and fleet admiral, and was a devout Muslim.
When Zheng He was a child he was captured by Ming armies and was brought to the capital of china. He was working as a slave to prince Zhu Di.
Zheng He rose up in the ranks of the slaves and became a close adviser of the prince, Zhu Di. When Zhu Di became emperor, he wanted to show the world china's power, so he instructed Zheng He to explore the world.
Zheng He built some of the largest wooden ships in the world. He had over 200 ships and 28000 men. He led 7 voyages that sailed throughout Asia and East Africa.
During Zheng He's voyages he established trade relations with foreign envoys from over 25 different countries. He also brought back goods such as ivory, camels, gold, and a giraffe.
Also, because Zheng He was a devout Muslim, he completed the Hajj on one of his journeys. Zheng He's voyages have had an effect on the rest of the world by extending China's glory and by spreading Islam along the way.
