Former Yilan County Council building which now houses the Yilan Story Museum
After the handover of Taiwan from Japan to the Republic of China in 1945, county assembly was set up according to the Institute of Organization for City and County Councils in 1946. In April 1950, the Taiwan Provincial Government promulgated the Outline for Implementing Local Autonomy for Cities and Counties. The administrative regions were reconfigured in September and the Yilan County Council was founded on 24 February 1951.
