And now we have another story to tell concerning this strange political evolution. As the shoguns became paramount over the mikados, so did the Hojo, the regents of the shoguns, become paramount over them, and for nearly one hundred and fifty years these vassals of a vassal were the virtual emperors of Japan. This condition of affairs gives a curious complication to the history of that country. In a previous tale it has been said that the father of Masago, the beautiful wife of the exiled prince, was named Hojo Tokimasa. He was a man of ability and was much esteemed and trusted by his son-in-law. After the death of Yoritomo and the accession of his son, Tokimasa became chief of the council of state, and brought up the young shogun in idleness and dissipation, wielding the power in his name. When the boy reached manhood and began to show ambition to rule, Tokimasa had him exiled to a temple and soon after assassinated. His brother, then twelve years old, succeeded as shogun. He cared nothing for power, but much for enjoyment, and the Hojo let him live his life of pleasure while they held the control of affairs. In the end he was murdered by the son of the slain shogun, who was in his turn killed by a soldier, and thus the family of Yoritomo became extinct. From that time forward the Hojo continued preeminent. They were able men, and governed the country well. The shoguns were chosen by them from the Minamoto clan, boys being selected, some of them but two or three years old, who were deposed as soon as they showed a desire to rule. The same was the case with the mikados, who were also creatures of the Hojo clan. One of them who had been deposed raised an army and fought for his throne. He was defeated and exiled to a distant monastery. Others were deposed, and neither mikados nor shoguns were permitted to reign except as puppets in the hands of the powerful regents of the realm. None of the Hojo ever claimed the office of shogun. They were content to serve as the power behind the throne. As time went on, the usual result of such a state of affairs showed itself. The able men of the Hojo family were followed by weak and vicious ones. Their tyranny and misgovernment grew unbearable. They gave themselves up to luxury and debauchery, oppressed the people by taxes to obtain means for their costly pleasures, and crushed beneath their oppressive rule the emperor, the shogun, and the people alike. Their cup of vice and tyranny at length overflowed. The day of retribution was at hand.
