Her reign, however, was not entirely free from the family strife which too often accompanied a change of sovereigns in Japan's early days. In addition to his legitimate offspring, Kusakabe, the Emperor Temmu left several sons by secondary consorts, and the eldest survivor of these, Prince Otsu, listening to the counsels of the Omi Court's partisans and prompted by his own well-deserved popularity and military prowess, intrigued to seize the throne. He was executed in his house, and his fate is memorable for two reasons: the first, that his young wife, Princess Yamanobe, "hastened thither with her hair dishevelled and her feet bare and joined him in death;" the second, that all his followers, over thirty in number, were pardoned--rare clemency in those days. Prince Otsu is said to have inaugurated a pastime which afterwards became very popular--the composition of Chinese verses. SLAVES The most important legislation of the Empress Jito's reign related to slaves.* In the year of her accession (690), she issued an edict ordering that interest on all debts contracted prior to, or during the year (685) prior to Temmu's death should be cancelled. Temmu himself had created the precedent for this. When stricken by mortal illness, he had proclaimed remission of all obligations, "whether in rice or in valuables," incurred on or before the last day of the preceding year. But Jito's edict had a special feature. It provided that anyone already in servitude on account of a debt should be relieved from serving any longer on account of the interest. Thus it is seen that the practice of pledging the service of one's body in discharge of debt was in vogue at that epoch, and that it received official recognition with the proviso that the obligation must not extend to interest. Debts, therefore, had become instruments for swelling the ranks of the slave class. *The senmin, or slave class, was divided into two groups, namely, public slaves (kwanko ryoko, and ko-nuhi), and private slaves (kenin and shi-nuhi).
