Hōjō Ujitsuna
Japanese daimyo of the Sengoku period
Hōjō Ujitsuna (北条 氏綱; 1487 – August 10, 1541) was a Japanese samurai lord of the Sengoku period. He was the son of Hōjō Sōun, the founder of the Go-Hōjō clan. He continued his father's quest to gain control of Kantō (the region around present-day Tokyo).
Biography
In 1524, Ujitsuna took Edo Castle, which was controlled by Uesugi Tomooki, thus beginning a long-running rivalry between the Hōjō and Uesugi families.
In 1526, Hojo Ujitsuna was defeated by Takeda Nobutora in the Battle of Nashinokidaira. Later, the Uesugi attacked and burned Tsurugaoka Hachimangū in Kamakura, which was a major loss to the Hōjō symbolically, because the earlier Hōjō clan from which they took their name fell in the Siege of Kamakura (1333). (Ujitsuna soon started rebuilding Tsurugaoka Hachimangū and was completed in 1540.) In 1530, his son Ujiyasu defeated Uesugi Tomooki in the Battle of Ozawahara.
The Uesugi attacked Edo again in 1535, when Ujitsuna was away fighting the Takeda; however, Ujitsuna returned and defeated Uesugi Tomooki reclaiming his lands.
When Uesugi Tomooki died in 1537, Ujitsuna took the opportunity to occupy Musashi province and seize Kawagoe Castle to secure his control of the Kantō.
In 1538, Ujitsuna then went on to win the battle of Kōnodai, securing Shimōsa Province for the Hōjō.
