憲政 上杉
Norimasa Uesugi was born in 1523 in Japan.
At the battle of Kawagoe in 1545, both major branches of the Uesugi family were defeated by Hojo Ujiyasu of the Hojo clan. In 1546, he was defeated again in the Battle of Odaihara, this time by Takeda Shingen.
Norimasa's campaigns only continued to be less and less successful. In 1551, Norimasa Uesugi was defeated once again by Hōjō Ujiyasu, and fled to Echigo Province, where he sought asylum with his vassal Nagao Kagetora. Nagao agreed to grant his lord shelter and protection, but only under certain conditions. Norimasa was forced to name Nagao his heir, and to grant him the titles of Lord of Echigo and Kantō Kanrei. Nagao then changed his name to Uesugi, to reflect his inheritance of Norimasa's lineage; he took the given name Terutora for a short time before choosing to be called Kenshin.
Norimasa Uesugi was the adoptive father of Uesugi Kenshin, one of the most famous warlords in Japanese history.
