Later, a third son of Go-Daigo's, Prince Morinaga, was appointed sei-i taishōgun together with his brother Norinaga, a move that immediately aroused Ashikaga Takauji's hostility.[1][5][6] Takauji believed the military class had the right to rule and considered himself not a usurper but, since the Ashikaga descended from a branch of the Minamoto clan, rather a restorer of Minamoto power.[4] When the Hōjō garrison at Rokuhara was destroyed in 1333, he immediately stepped in and installed there his office (bugyōsho).[2] It kept order in the city and in general took over the original's function.[2] Extending its authority to controlling travel along highways, issuing passports and exercising rights previously belonging to the shogunate's deputies (the Rokuhara Tandai), Takauji showed he believed that samurai political power must continue.[2] His setting himself apart as a representative of the military made him an aggregation point for the warriors' discontent.[2] Samurai saw him as the man who could bring back the shogunate's heyday, and therefore his strength was superior to that of any other samurai, Nitta Yoshisada included.[2] His only obstacle to the shogunate was Prince Morinaga.[2]
