The genealogies which fill pages of the Records from the days of Jimmu downwards point clearly to the growth of a powerful feudal aristocracy, for the younger sons born to successive sovereigns bear, for the most part, names indicative of territorial lordship; but it seems justifiable to conclude that the first great impetus to that kind of decentralization was given by Sujin's despatch of the Shido shoguns.
Thus in the provinces of Omi, of Suruga, of Mutsu, of Iwashiro, of Iwaki, of Echigo, of Etchu, of Echizen, of Bizen, of Bitchu, of Bingo, of Harima, of Tamba, and elsewhere, there are found in later ages noble families all tracing their descent to one or another of the Shido shoguns despatched on the task of pacifying the country in the days of the Emperor Sujin.
Some fought resolutely, but ultimately all that had not perished under the swords of the Minamoto obeyed Munemori's orders to embark, and the evening of the 23rd of March saw the Taira fleet congregated in Shido Bay and crowded with fugitives.
But though the pestilence was stayed, it brought an aftermath of lawlessness and produced much unrest in the regions remote from Yamato. Sujin therefore organized a great military movement, the campaign of the Shido shogun, or "Generalissimo of the four Circuits."* *The term "do" indicates a group of provinces.
