At times of war, these could form spear or musket units, which made possible infantry-centered group tactics. They also established hierarchical relationships between certain powerful vassals and lower-class samurai, in which the former were yorioya, or “surrogate parents,” to the latter. Other common laws regulated marriage, restricted land sales, and forbade farmers from defaulting on taxes (in the form of rice or barley) or absconding en masse.ĭaimyō sought to ascertain the value of their vassals’ land, which was used as a basis for taxation and requirements for military service.

The aim was to concentrate power in the daimyō, so as to achieve stability in the domain. Private quarrels between vassals were not permitted, and the daimyō made rulings on any troubles that arose. They introduced their own domain laws to control vassals and territory, which often ruled that both parties in any dispute could be punished. In the rest of the country, a number of daimyō established regional power to fill the vacuum.

The Ōnin War dragged on for 11 years, by the end of which time the shogunate’s power was limited to just the province of Yamashiro (including Kyoto). In 1467, a dispute over the shogunal succession in Kyoto degenerated into open warfare. The Ashikaga clan had established the Muromachi shogunate in 1338, but its control in the east of the country slipped when the 1454 assassination of a shogunal deputy at Kamakura sparked decades of regional conflict. Oda Nobunaga was born in 1534, in the middle of the Warring States period (1467–1568).
