Abolition of the han system

The abolition of the han system (廃藩置県, haihan-chiken) in the Empire of Japan and its replacement by a system of prefectures in 1871 was the culmination of the Meiji Restoration begun in 1868, the starting year of the Meiji period. Under the reform, all daimyos (大名, daimyō, feudal lords) were required to return their authority to the Emperor Meiji and his house. The process was accomplished in several stages, resulting in a new centralized government of Meiji Japan and the replacement of the old feudal system with a new oligarchy.
