History of the Republic of China
On the other hand, since the failure of the Second Revolution, Sun Yat-sen and his allies were trying to rebuild the revolutionary movement. In July 1914 Sun established the Chinese Revolutionary Party (). He felt that his failures at building a consistent revolutionary movement stemmed from the lack of cohesiveness among its members. To that end, Sun required that party members to be totally loyal to Sun and follow a series of rather harsh rules. Some of his earlier associates, including Huang Xing, balked at the idea of such authoritarian organization and refused to join Sun. However, they agreed that the republic must not revert to imperial rule.
Liaoning
In the 20th century, the province of Fengtian was set up in what is Liaoning today. When Japan and Russia fought the Russo-Japanese War in 1904–1905, many key battles took place in Liaoning, including the Battle of Port Arthur and the Battle of Mukden, which was, to that point, the largest land battle ever fought. During the Warlord Era in the early twentieth century, Liaoning was under the Fengtian Clique, including Zhang Zuolin and his son Zhang Xueliang. The province first received its present name on January 29, 1929; the Zhongdong Railway Incident took place later that year.RE In 1931, Japan invaded and the area came under the rule of the Japanese-controlled puppet state of Manchukuo. The Chinese Civil War that took place following Japanese defeat in 1945 had its first major battles (the Liaoshen Campaign) in and around Liaoning.
At the founding of the People's Republic of China in 1949, Liaoning did not exist; instead there were two provinces, Liaodong and Liaoxi, as well as five municipalities, Shenyang, Lüda (present-day Dalian), Anshan, Fushun, and Benxi. These were all merged into "Liaoning" in 1954, and parts of former Rehe province were merged into Liaoning in 1955. During the Cultural Revolution Liaoning also took in a part of Inner Mongolia, though this was reversed later.
