鳥羽天皇
Born in Kyoto to a noble family, he lived during the traumatic transition of power between the old court nobles and the new samurai warriors. After the start of the age of Mappō, Buddhism was considered to be in decline and no longer as effective a means of salvation. These cultural shifts during his lifetime led to a sense of melancholy in his poetry. As a youth, he worked as a guard to retired Emperor Toba, but in 1140 at age 22, for reasons now unknown, he quit worldly life to become a monk, taking the religious name .
