Civil war (1945–49)
In a little more than four years after Japan’s surrender, the CCP and the People’s Liberation Army (PLA; the name by which communist forces were now known) conquered mainland China, and, on Oct. 1, 1949, the People’s Republic of China was established, with its capital at Beijing (the city’s former name restored). The factors that brought this about were many and complex and subject to widely varying interpretation, but the basic fact was a communist military triumph growing out of a profound and popularly based revolution. The process may be perceived in three phases: (1) from August 1945 to the end of 1946, the Nationalists and communists raced to take over Japanese-held territories, built up their forces, and fought many limited engagements while still conducting negotiations for a peaceful settlement; (2) during 1947 and the first half of 1948, after initial Nationalist success, the strategic balance turned in favour of the communists; and (3) the communists won a series of smashing victories beginning in the latter part of 1948 that led to the establishment of the People’s Republic.
