Shimazu Tadatsune

This is a Japanese name; the surname is {{{1}}}. Shimazu Tadatsune. Shimazu Tadatsune (島 津 忠 恒, November 27, 1576 - April 7, 1638) was a samurai and daimyō of Satsuma's domain, the first to rule him as an official han (fief) during the Tokugawa shogunate and the first Japanese in ruling the Kingdom of Ryūkyū.

Tadatsune was the third son of Shimazu Yoshihiro. Because his older brother Shimazu Yoshihisa had no children and his other brother, Shimazu Hisakazu died in Korea, he was named successor in the leadership of the Shimazu clan so he took the name of Iehisa (家 久).

He also participated in the Japanese invasions of Korea summoned by Toyotomi Hideyoshi between 1592 and 1598.

Formally submitted to Tokugawa Ieyasu in 1602 and as a reward for his loyalty was appointed as Matsudaira Iehisa. In 1603 their lands were valued at 605,000 koku.

In 1609, Tadatsune led an expedition to the Ryūkyū Kingdom, subjugating it with the aim of trading with China. The inhabitants were allowed to be semi-independent and were not officially annexed to Japan until the Meiji Restoration (1868).
