nagaya -lrb- 長屋王 `` nagaya-no-ōkimi '' or `` nagaya-ō '' -rrb- -lrb- 684 -- 20 march 729 -rrb- was a politician of the nara period and an imperial prince of japan , a son of prince takechi -lrb- grandson of emperor temmu -rrb- .
his father was prince takechi and his mother princess minabe -lrb- a daughter of emperor tenji and empress gemmei 's sister -rrb- .
he married princess kibi -lrb- his cousin , a daughter of empress gemmei and empress genshō 's sister -rrb- .
he had a great power in politics because he was a member of the imperial family of the best birth , and there were no other competitive imperial members in those days .
a big residence was allocated to him in the very good part of heijō-kyō .
the fujiwara clan was the most powerful competitor of nagaya .
fujiwara no fuhito , the leader of the house , had been the most powerful courtier in the court in those days when this country was reigned by empress genshō , a cousin of nagaya 's .
after fuhito 's death in 720 , he seized a complete power in the court .
this power shift was the source of later conflicts between him and fuhito 's four sons -lrb- muchimaro , fusasaki , maro and umakai -rrb- in the reign of emperor shōmu .
in 729 , the four sons charged him with a false crime and nagaya received the death penalty .
he was forced to commit suicide .
his wife , princess kibi , and his children were killed at the same time .
