Zheng He in the early 1400s led the largest exploration with seven voyages into the Indian Ocean which demonstrated the Chinese marine technology and navigation. First, he went from South China through the Indian Ocean to be recognized and get gifts from other rulers. His voyages had no intentions of conquering or colonizing but were ready to apply military force to anyone who disrespected him i.e., towards the end of his voyage he met pirates in Sumatran port whom he fought and killed 5,000 and took the leader to be beheaded in China. Other voyages include excursions to Hormuz, Arab port at the Persian Gulf, and the coast of East Arica where he carried giraffes ad skins. On his seventh and final voyage (1431 to 1433) he is believed to have died and gotten burried off the coast of India.
