In the 1350s, the Kannō Incident and its aftermath divided and nearly destroyed the early regime. On the surface the incident looks like a personal struggle between Ashikaga Tadayoshi, Takauji's brother, against the Kō brothers, backed by Takauji. The conflict can be however pinpointed to differences in opinion regarding the estate system and, behind these differing opinions, the different bureaucracies controlled by Takauji and Tadayoshi. On the whole Takauji was the innovator while Tadayoshi played the conservative, wanting to preserve the policies of the past. In his capacity as a military leader of vassal bands, Takauji did two things that conflicted with Tadayoshi: he appointed vassals to "shugo" posts as a reward for battlefield heroics, and he divided the "shōen" estates giving half of it to his vassals in fief or as stewardships. Tadayoshi strenuously contested these policies through the drafting of the Kemmu Formulary that opposed the appointment of "shugo" as a reward for battlefield service. He also opposed any sort of outright division of estate lands in his capacity as the leader of the Board of Coadjutors. There was a clear division between the policies of Takauji and his brother Tadayoshi.
