The archipelago that remains split between two rival governments after a civil war
In short: Lying off the coast of mainland China, the Matsu Islands are a unique geopolitical relic. While they are governed by Taiwan today, they were once part of an intact county in Fujian province. Following the 1949 Chinese Civil War, the region was partitioned, creating a rare administrative split that persists today.
The Matsu Islands consist of 19 islands and islets located in the East China Sea. Historically, these islands were part of a unified Lienchiang County within China’s Fujian province. However, the conclusion of the Chinese Civil War in 1949 fundamentally altered their status. As the Nationalist government retreated to Taiwan, they maintained control over the offshore Matsu archipelago, while the mainland portion of the original county fell under the administration of the newly formed People's Republic of China.
This division makes Lienchiang County a singular case in modern geography, as it is the only former administrative unit currently managed by two competing authorities. The islands were not always a cohesive group; before 1949, residents often identified primarily as Fujianese rather than as part of a collective 'Matsu' identity. The name itself derives from a local temple dedicated to the goddess Mazu, which is said to house her burial site on the main island of Nangan.
The strategic importance of the islands became clear during the 20th century. In 1958, the archipelago was the site of an intense international crisis when mainland communist forces launched heavy bombardments, demanding a Nationalist surrender. The conflict was only de-escalated after the United States intervened by positioning its 7th Fleet in the area. For decades, the islands remained under strict military administration, a period that only ended with the restoration of civilian rule in 1992.
Today, the islands serve as a reminder of the complex legacy of the Chinese Civil War. While they were once a peripheral region with little connection to Taiwan—which was under Japanese colonial rule for much of the early 20th century—they are now firmly integrated into the Republic of China's administrative structure. The archipelago continues to navigate its identity, balancing its historical roots in Fujian with its contemporary status as a territory under the jurisdiction of Taiwan.
