I'm assuming you are referring to the communist revolution in China. It was a continuous struggle but it begun in 1927. In 1911 the Manchu imperial dynasty was overthrown in the revolution known as double tenth. The last emperor of China, Pu Yi who was just a boy at a time abdicated, and China was proclaimed a republic in November 1911 in Nanjing. However the power was soon taken by the General Yuan Shikai, he struck an agreement with the republicans and for allowing the imperial rule to fall, he was proclaimed by them the president. The revolution of Double Tenth is argued to be actually the revolution of provinces against the centralized rule, not a revolution motivated by ideological reasons. Yuan's Shikai rule didn't last long, he was forced to abdicate in 1916 when he attempted to proclaim himself an emperor. He died soon after. This marked the beginning of the warlord era, time in which China was ruled by a bunch of provincial warlords, each with his own army and attempting to spread his own influence. In 1922 the republicans which now were the GMD and had grown significantly in power formed an alliance with the CCP(China Communist Party) which was inspired by the bolsheviks in Russia. Together they managed to swiftly end the Warlords rule, in 1928 GMD has captured Beijing. But GMD which was a nationalist party, feared the popular support which the CCP had. In 1927 they begun purification, mass murdering of all the communist they could get their hands on. 1927 is seen as the official date for the beginning of the revolution. CCP fled to the mountains of Jiangsi pursued by the GMD. The fightings lasted till 1937. In 1937 the second United Front was signed between the GMD and CCP, this time against Japan but as has Mao stated who was already in power at a time "our fixed policy should be 70% expansion, 20% dealing with the GMD and 10% resisting the Japanese." The open fightings broke out again in 1946 and lasted till 1949 when the leader of GMD fled to Taiwan. You can divide the revolution into two phases one from (1927 till 1937) and second one from (1946 till 1949). You could I suppose argue that the conflict was continuous from 1927 till 1949 but definitely not from 1911 as the CCP was only formed in 1921. Hope this helps.

It was most definitely two separate revolutions. The first revolution in 1911 was a revolution against the Imperial Qing government, by a wide range of dissenters who were united by being anti-monarchists - it was a revolution against the monarchy, not dissimilar to the French Revolution. It was also a revolution against traditional Chinese culture, as many revolutionaries were intellectuals who believed the only way to revive China from the 'Century of Humiliation', was to learn from their oppressors and implement radical westernization. The reason why many opposed the monarchy was its slow westernization.

I would argue the end of the Chinese Civil War in 1949 was not a revolution - indeed no one in China (I am from Hong Kong) ever refers to it as a revolution. It is true that the Civil War led to a change in government - from an ideally Republican, but realistically autocratic Nationalist government to a Communist one - but in reality, not much changed in the early years of Communist rule. It should be remembered that at the start of Communist rule, participation from other, Communist-approved political parties was allowed, and there was still an emphasis on cooperating with local bourgeoisie - partial collectivization did not occur until the First Five-Year Plan in 1953. Intellectual thought was not widely suppressed in China. The year 1949 did not represent a drastic change in society, mainly due to the fact that the Communists were still trying to consolidate their power.

In my opinion, the Cultural Revolution was the true second 'revolution' of China, as it represented a drastic change in culture for the whole of China, with its repercussions still felt in the modern day. Everything considered 'not Communist enough' was suppressed - traditional Chinese culture, religion, social values - and in return, everyone turned to the worship of Communism, and most importantly, Mao. I still remember visiting a farmer on the edge of Guangdong, not that far inland in China, and right above his television, was a portrait of Mao. The year was 2010, 40 years after the Cultural Revolution.

Therefore, China did have two revolutions, but the second one was not in 1949, but rather in 1966.
