Taichung (/ˌtaɪˈtʃʊŋ/, Wade–Giles: Tʻai-chung, Pinyin Táizhōng), officially Taichung City, is a special municipality in central Taiwan. Taichung is Taiwan's second-largest city, with more than 2.86 million residents, making it the largest city in Central Taiwan. It serves as the core of the Taichung–Changhua metropolitan area, Taiwan's second-largest metropolitan area.
Located in the Taichung Basin, the city was initially developed from several scattered hamlets helmed by the Taiwanese indigenous peoples. It was constructed to be the new capital of Taiwan Province and renamed "Taiwan-fu" in the late Qing dynastic era between 1887 and 1894. During the Japanese era from 1895, the urban planning of present-day Taichung was performed and developed by the Japanese. The urban area of Taichung was organized as a provincial city from the start of ROC rule in 1945 until 25 December 2010, when the original provincial city and Taichung County were merged into a new special municipality.
