The Penghu (/ˈpʌŋˈhuː/ PUNG-HOO, Hokkien POJ: Phîⁿ-ô͘ or Phêⁿ-ô͘ ) or Pescadores Islands are an archipelago of 90 islands and islets in the Taiwan Strait, about 50 kilometres (25 nautical miles) west of the main island of Taiwan across the Penghu Channel, covering an area of 141 km (54 sq mi). The archipelago collectively forms Penghu County. The largest city is Magong, on the largest island, which is also named Magong.
The Penghu islands first appear in the historical record in the Tang dynasty and were inhabited by Chinese people under the Southern Song dynasty, during which they were attached to Jinjiang County of Fujian. The archipelago was formally incorporated as an administrative unit of China in 1281 under Tong'an County of Jiangzhe Province in the Yuan dynasty. It continued to be controlled by Imperial China with brief European occupations by the Dutch Empire (1622–1624) and Second French colonial empire (1885), until it was ceded to the Empire of Japan in 1895. Japan’s surrender in 1945 ended its colonial rule over the Islands, which has since then been governed by the Republic of China (ROC). Under the terms of the Sino-American Mutual Defense Treaty and the subsequent Taiwan Relations Act between the ROC and the United States, Penghu is defined and geographically acknowledged as part of Taiwan.
