Emperor Go-Yōzei
On March 24, 1603, Tokugawa Ieyasu received the title of "shōgun" from Emperor Go-Yōzei. Ieyasu was 60 years old. He had outlasted all the other great men of his times: Nobunaga, Shingen, Hideyoshi, and Kenshin. As "shōgun", he used his remaining years to create and solidify the Tokugawa shogunate, which ushered in the Edo period, and was the third shogunal government (after the Kamakura and the Ashikaga). He claimed descent from the Minamoto clan who had founded the Kamakura shogunate, by way of the Nitta clan. His descendants would marry into the Taira clan and the Fujiwara clan. The Tokugawa shogunate would rule Japan for the next 260 years.
