Kagekatsu was the second son of [[Nagao Masakage|Nagao Echizen no Kami Masakage]] (d.[[1564]]), husband of [[Uesugi Kenshin]]'s elder sister Ayahime. As a child he was known as Kiheiji. Kenshin adopted him and named him part heir alongside [[Uesugi Kagetora]] ([[Hojo Ujiyasu|Hojo Ujiyasu's]] 7th son, adopted by Kenshin in [[1569]]). Following Kenshin's death in [[1578]] Kagekatsu found a pretext to feud with Kagetora and the resulting civil war became known as the [[Otate no Ran]]. By [[1579]] Kagekatsu had gained the upper hand and forced Kagetora to commit suicide. This bloody division allowed [[Oda Nobunaga]]'s generals (headed by [[Shibata Katsuie]]) to conquer the Uesugi's lands in [[Kaga province|Kaga]], [[Noto province|Noto]], and [[Etchu province|Etchu]]. | Kagekatsu was the second son of [[Nagao Masakage|Nagao Echizen no Kami Masakage]] (d.[[1564]]), husband of [[Uesugi Kenshin]]'s elder sister Ayahime.
