Daitō-ryū Aiki-jūjutsu
With the outlawing of the samurai class and the prohibition against carrying swords (Haitōrei Edict) apparentally Sokaku decided to emphasize the empty handed, jujutsu oriented, techniques of his ancestor's art. These apparently were 'oshiki-uchi', or secret teachings of the Aizu clan, up to that point. These, along with other skills he had acquired, were combined to create an art which he named first 'Daitō-ryū jūjutsu' and later 'Daitō-ryū Aiki-jūjutsu'.
