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.
Rail transport in China
During the Republic of China era from 1912 until 1949, the development of the railway network in China slowed due to repeated civil wars and the invasion of Japan in the Second Sino-Japanese War. One of the few exceptions was in Northeastern China (Manchuria). The Russians opened the Chinese Eastern Railway in 1901; after the Russo-Japanese War (1904–1905), the Japanese gained control of the portion of the Chinese Eastern Railway south of Changchun, using it to create the South Manchuria Railway Company (SMR) in 1906; this company was often referred to as "Japan's East India Company in China" due to its extensive influence in the political and economic situation of Manchuria. During the reign of the Fengtian warlords from 1912 till 1931, numerous privately owned railway companies were formed; after the Japanese staged the Mukden Incident on 18 September 1931 as a pretext for invading Manchuria and the subsequent establishment of a puppet state called "Manchukuo", these private railways were nationalised and merged to form the Manchukuo National Railway (MNR). In 1935, the Japanese bought the northern portion of the Chinese Eastern Railway from the Soviet Union and merged it into the MNR. In addition to the MNR and SMR, several other railway companies were established in the Japanese-occupied parts of China, including the North China Transportation Company, the Central China Railway, and the East Manchuria Railway. In 1945, just after the Second Sino-Japanese War, there were of rail, of which nearly half - - was located in Manchuria.
