Whatever might have been the real motive of Yasutoki and his legal councillors, the very act of the compilation cannot in itself fail to betray the consciousness on the part of the Shogunate that it had already a sufficiency of test cases decided to supply models for the decision of most of the disputes that might be brought before them in the future. Or we might say that the Hojo became confirmed in their belief that the Shogunate was now so firmly established as not to be easily shaken at its foundation, and that they could henceforth command in the name of a regular government without any fear of serious disturbances. Certainly their victory in the civil war must have rid them of any apprehension of danger from the side of Kyoto. This compilation was issued in the year 1232, that is to say, about fifty years after the founding of the Kamakura Shogunate. Thus we can see that this half-century had wrought an important change in the history of Japan. During this time the military regime was enabled to strike a firm root deep into the national life of the Japanese. The family of the Minamoto soon became extinct by the death of the second son of Yoritomo, and scions of a Fujiwara noble and then some of the imperial princes were brought from Kyoto one after another as the successors to the Shogunate. Yet they were all but tools in the capable hands of the Hojo family, which remained the real master of the military government of Kamakura. In course of time, the Hojo also fell, but other military families successively arose to power, and the military regime was kept up by them in Japan until the middle of the nineteenth century. It is true that those changes in the headship and in the location of the Shogunate caused as a matter of fact corresponding changes in the nature of the respective military regime. The Shogunate of the Ashikaga family was of a different sort from that of Kamakura, while that of the Tokugawa at Yedo was again of another type than the Ashikaga's at Kyoto. Throughout all these different Shogunates, however, certain common characteristics prevailed, so that a wide gap may be discerned between them as a whole and the government of the Fujiwara courtiers. And those characters indeed have their origin all in this first half century of the Kamakura Shogunate.
