Career
In early 1160, Shinzei"s ally Taira no Kiyomori left the capital with much of his family, thus providing Nobuyori"s faction (and his allies, the Minamoto clan) to make a move for power. Some believe this may have been intentional on Kiyomori"s part, laying a trap for the Minamoto. Nobuyori and the Minamoto set fire to the Sanjō Palace and abducted both Emperor Nijō and the cloistered Emperor Go-Shirakawa.
They then turned on Shinzei"s home, destroying it and killing all those inside, with the exception of Shinzei himself, who escaped only to be captured in the mountains near Kyoto and decapitated soon afterward.
