Chinese Civil War: Chinese Communist forces occupy Guangzhou.

The People's Liberation Army (PLA) is the principal military force of the People's Republic of China and the armed wing of the Chinese Communist Party (CCP). The PLA consists of five service branches: the Ground Force, Navy, Air Force, Rocket Force, and Strategic Support Force. It is under the leadership of the Central Military Commission (CMC) with its chairman as commander-in-chief.The PLA can trace its origins during the republican era to the left-wing units of the National Revolutionary Army (NRA) of the Kuomintang (KMT) when they broke away on 1 August 1927 in an uprising against the nationalist government as the Chinese Red Army before being reintegrated into the NRA as units of New Fourth Army and Eighth Route Army during the Second Sino-Japanese War. The two NRA communist units were reconstituted into the PLA on 10 October 1947.A majority of military units around the country are assigned to one of five theater commands by geographical location. The PLA is the world's largest military force (not including paramilitary or reserve forces) and constitutes the second largest defense budget in the world. It is also one of the fastest modernizing militaries in the world, and has been termed as a potential military superpower, with significant regional defense and rising global power projection capabilities.PRC law explicitly asserts the leadership of the CCP over the armed forces of China and designates the CMC as the nationwide military command of the People's Republic of China. The Party CMC operates under the name of the State CMC for legal and governmental functions and as the ceremonial Ministry of National Defense (MoD) for diplomatic functions. The PLA is obliged to follow the principle of the CCP's absolute civilian control of the military under the doctrine of "the party commands the gun" (Chinese: ; pinyin: Dng zhhu qing) In this sense, the PLA is not a national army of the type of traditional nation-states, but a political army or the armed branch of the CCP itself since its allegiance is to the party only and not the state or any constitution. At present, the Chairman of the Central Military Commission is customarily also the General Secretary of the Chinese Communist Party.Since 1949, China has used nine different military strategies, which the PLA calls "strategic guidelines". The most important came in 1956, 1980, and 1993. In times of national emergency, the People's Armed Police (PAP) and the China Militia act as a reserve and support element for the PLAGF. Politically, the PLA is represented in the National People's Congress with 294 deputies, all of whom are CCP members.

The Chinese Civil War was a civil war in China fought between the Kuomintang (KMT)-led government of the Republic of China (ROC) and forces of the Chinese Communist Party (CCP) lasting intermittently after 1927.

The war is generally divided into two phases with an interlude: from August 1927 to 1937, the KMT-CCP Alliance collapsed during the Northern Expedition, and the Nationalists controlled most of China. From 1937 to 1945, hostilities were put on hold, and the Second United Front fought the Japanese invasion of China with eventual help from the Allies of World War II. The civil war resumed with the Japanese defeat, and the CCP gained the upper hand in the final phase of the war from 1945 to 1949, generally referred to as the Chinese Communist Revolution.

The Communists gained control of mainland China and established the People's Republic of China (PRC) in 1949, forcing the leadership of the Republic of China to retreat to the island of Taiwan. Starting in the 1950s, a lasting political and military standoff between the two sides of the Taiwan Strait has ensued, with the ROC in Taiwan and the PRC in mainland China both officially claiming to be the legitimate government of all China. After the Second Taiwan Strait Crisis, both tacitly ceased fire in 1979, however, no armistice or peace treaty has ever been signed.
