It would be a mistake to suppose that such a momentous change was effected without any disturbance. The Kyoto nobles, who were unable at first to see the political importance of the establishment of the Shogunate in an insignificant provincial village, were gradually awakened to the real loss which they would surely suffer by it, and longed to recover the reins, which they had once forgotten to keep and guard. Besides, there were many malcontent warriors both within and without the Shogunate. For after the death of Yoritomo, though the title of Shogun was inherited by his two sons, one after the other, the real power of the Shogunate fell into the hands of his wife's relations, the family of Hojo. Warriors of other families were excluded from a share in the military government, and they, dissatisfied on that account, wished for some change in order to overthrow the Hojo. Needless to say that outside of the Shogunate ambitious men were not lacking, who desired to set up another Shogunate in place of that at Kamakura, if they could. All these discontented soldiery allied themselves with the Kyoto nobles, and caused the civil war of Jokyu to ensue between them and the Shogunate represented by the Hojo family. The war ended in the defeat of the former, and the Shogunate emerged out of the war far stronger than before. Thirteen years after the war, the first compilation of laws of the Shogunate was undertaken by Yasutoki Hojo. It is called "the compiled laws of the Joyei," Joyei being the name of the era in which the compilation was issued. This compilation was not so much a work of elaborate systematisation, nor an imitation of foreign laws, as was the reform legislation of the Taiho. Rather it should be called a collection of abstracts of particular law cases decided by the judicial staff of the Shogunate. It is therefore an outcome of necessitated experiences like English "case-law", and had not the character of statute laws or provisions deduced from a certain fundamental legal principle in anticipation of all probable occurrences. The object of the compilation is clearly stated in the epilogue written by Yasutoki himself. According to this, it was far from the motive of the compilers to displace the old system of legislation by the promulgation of the new one. Old laws became a dead letter, without being formally abrogated, while the new code was issued only for the practical benefit of the people in charge of various businesses.
