The religious fanaticism of the Emperor Shomu and his consort, Komyo, brought disorder into the affairs of the Imperial Court, and gave rise to an abuse not previously recorded, namely, favouritism with its natural outcome, treasonable ambition. It began to be doubtful whether the personal administration of the sovereign might not be productive of danger to the State. Thus, patriotic politicians conceived a desire not to transfer the sceptre to outside hands but to find among the scions of the Imperial family some one competent to save the situation, even though the selection involved violation of the principle of primogeniture. The death of the Empress Shotoku without issue and the consequent extinction of the Emperor Temmu's line furnished an opportunity to these loyal statesmen, and they availed themselves of it to set Konin upon the throne, as will be presently described. In this crisis of the empire's fortunes, the Fujiwara family acted a leading part. Fuhito, son of the illustrious Kamatari, having assisted in the compilation of the Daika code and laws, and having served throughout four reigns--Jito, Mommu, Gemmyo, and Gensho--died at sixty-two in the post of minister of the Right, and left four sons, Muchimaro, Fusazaki, Umakai, and Maro. These, establishing themselves independently, founded the "four houses" of the Fujiwara. Muchimaro's home, being in the south (nan) of the capital, was called Nan-ke; Fusazaki's, being in the north (hoku), was termed Hoku-ke; Umakai's was spoken of as Shiki-ke, since he presided over the Department of Ceremonies (Shiki), and Maro's went by the name of Kyo-ke, this term also having reference to his office. The descendants of the four houses are shown in the following table:
