Following the death of [[Uesugi Kenshin]] in [[1578]], the Uesugi domain had fallen into a year-long civil war (see [[Otate no ran]]). Taking advantage of the Uesugi's feud, Shibata Katsuie and Sassa Narimasa, Oda Nobunaga's spearheads in the [[Hokuriku]] Region, began a drive for the borders of [[Echigo province|Echigo]] itself. By [[1581]] the Oda had taken [[Toyama castle]] and were entrenched in [[Etchu province|Etchu]], which Shibata and Sassa set about clearing of both Uesugi and [[Ikko-Ikki]] resistance. | Following the death of [[Uesugi Kenshin]] in [[1578]], the Uesugi domain had fallen into a year-long civil war (see [[Otate no ran]]).
