Captain F. Brinkley, Japan: Its History, Arts, and Literature (1902 and 1910)
“ A permanent military force was to be maintained by each province. To these measures the Emperor consented, and in 1192 bestowed upon Yoritomo the title of Sei-i Tai Shōgun or Barbarian-subduing Generalissimo. He was one of the ablest rulers of Japan, but a heartless tyrant. He looked with disfavour upon all other persons of ability or ambition, and killed off all possible rivals, including his brother Yoshitsune. He left no successor; his own children were weaklings from whom the power soon passed to the family of Yoritomo's wife, the Hōjō family. ”
