1949: The Unfinished War and the Political Fiction That Has Governed the Strait Ever Since
The Taiwan question is a civil war outcome that was never formalized. When Chiang Kai-shek’s Nationalist forces retreated to Taiwan in 1949 following their defeat by Mao’s Communist forces on the mainland, neither side accepted the result as permanent. The People’s Republic of China, proclaimed by Mao on October 1, 1949, claimed sovereignty over all Chinese territory including Taiwan. The Republic of China government, relocated to Taipei, continued to claim sovereignty over the mainland and to represent China in the United Nations until its expulsion in 1971. Both governments maintained, for decades, that there was one China and that they were its legitimate government. The dispute was not about whether Taiwan was Chinese. It was about which government was China’s.
This founding reality has shaped every aspect of the Taiwan question ever since, in ways that contemporary analysis often underweights. The claim that China makes on Taiwan is not a territorial acquisition claim of the kind that motivated nineteenth-century European imperialism or twentieth-century Soviet expansion. It is a reunification claim grounded in the argument that the civil war produced an illegitimate outcome — that the Communist victory was valid but that the Nationalist retreat to Taiwan allowed the defeated party to perpetuate a regime that should have been extinguished in 1949. The Chinese Communist Party’s Taiwan policy is, in this reading, the completion of an unfinished military and political process rather than the initiation of a new one.
The evolution of Taiwanese political identity over the subsequent seven decades has created a fundamental mismatch between this founding reality and the political situation that actually exists. The Republic of China that retreated to Taiwan in 1949 was a government in exile asserting sovereignty over a territory it had never effectively governed. The Taiwan of 2026 is a democracy of 23 million people who have governed themselves for generations, who have developed a distinct political identity, and of whom a strong majority prefers the status quo of de facto independence or formal independence over reunification with the PRC under any arrangement currently on offer. The civil war framing that gives Beijing its legal and historical claim describes a political reality that no longer exists on the Taiwan side.
The fiction that both sides maintained — one China, competing governments — served a stabilizing purpose for decades by providing both sides with a framework within which they could manage the relationship without either side having to formally accept the other’s existence. Taiwan’s incremental moves toward a distinct political identity — the lifting of martial law in 1987, the first direct presidential election in 1996, the constitutional amendments that have narrowed the gap between formal and substantive statehood — have eroded this fiction from the Taiwanese side. China’s insistence that reunification is inevitable and its hardening of the timeframe for achieving it have eroded it from the Chinese side.
The international community’s participation in the fiction is the element that Chinese diplomacy has invested most heavily in maintaining. The one-China policy that most countries maintain in their formal diplomatic relations with the PRC — including the United States — represents an acceptance that there is one China and that the PRC is its government, in exchange for the PRC not insisting that this formal position translate into concrete opposition to Taiwan’s functional relationships with the rest of the world. The arrangement works as long as both sides observe its implicit bargain. It frays when China demands that countries operationalize their formal position by refusing Taiwan the diplomatic and military support it needs to maintain its de facto independence.
The civil war never ended. It was paused by American military intervention in the strait in 1950, frozen by the deterrence architecture of the Cold War, managed by the economic integration of the 1990s and 2000s, and is now being reactivated by a Chinese leadership that has decided the pause has lasted long enough. The fiction that made the pause possible is wearing thin. What replaces it will be determined not by legal argument but by the balance of power in 110 miles of contested water.
