Historical Evolution
The history of the Penghu Islands spans several dynasties and international shifts. The islands first appeared in historical records during the Tang dynasty. By the Song dynasty, Chinese inhabitants had settled the islands, at which time they were attached to Jinjiang County in Fujian.
In 1281, the archipelago was formally incorporated as an administrative unit under Tong'an County. Throughout the following centuries, the islands remained under the control of Imperial China, though they experienced brief occupations by the Dutch (1622–1624) and the Second French Colonial Empire (1885). In 1895, the islands were ceded to the Empire of Japan.

Following the surrender of Japan in 1945, the administration of the islands was transferred to the Republic of China. The Treaty of Taipei, signed in 1952, provided legal support for the Republic of China's claim to the territory. Today, under the terms of the Sino-American Mutual Defense Treaty and the Taiwan Relations Act, Penghu is geographically acknowledged as part of Taiwan.

Administrative Structure and Governance
Penghu County is governed by the Penghu County Government and the Penghu County Council. The current County Magistrate is Chen Kuang-fu. The county is divided into one city and five rural townships, which manage various villages across the islands.

In terms of infrastructure, Penghu is powered by the Chienshan Power Plant, a 140 MW diesel-fired facility, and the Hujing Power Plant on Table Island. To improve energy stability, the Taiwan-Penghu Undersea Cable Project was approved in 2010 to connect the islands to the main electrical grid of Taiwan Island.
Demographics and Economy
As of December 2014, the population of Penghu was approximately 101,758. While the population saw significant growth during the mid-20th century, it has experienced fluctuations in more recent decades. The islands are home to diverse linguistic traditions, with Southern Min (Hokkien) being a prominent language.

The economy is supported by various sectors, including education, represented by institutions such as the National Penghu University of Science and Technology. Transportation is facilitated by air and water routes, including Qimei Airport, which provides vital connectivity to the outlying islands.
