Tokugawa Ieyasu's

One of the most significant figures in Japanese history, Ieyasu was a warrior, statesman and founder of the Tokugawa dynasty of shoguns. Tokugawa Ieyasu was born Matsudaira Takechiyo in 1542, son of the lord of the province of Mikawa. At the time of his birth, Japan was convulsed by civil war, with violent feuds between territorial lords which had lasted for nearly a century. When he was four Ieyasu was sent as a hostage to secure an alliance between his clan and the neighbouring Imagawa clan. He was raised at their court and given the education suitable for a nobleman. In 1567 Ieyasu, whose father's death had left him as leader of the Matsudaira, allied with Oda Nobunaga, a powerful neighbour. It was at this time that he changed his name from Matsudaira to Tokugawa, which was the name of the area from which his family originated. He also changed his personal name to Ieyasu, so he was now known as Tokugawa Ieyasu. Ieyasu spent the next decade-and-a-half campaigning with Nobunaga while expanding his own influence and wealth. He had by now gained a considerable military reputation.
