60th Anniversary Of Communist Party, Beijing, China

After Yuan Shikai's death in 1916, China was politically fragmented, with an internationally recognized but virtually powerless national government seated in Peking (Beijing). Warlords in various regions exercised actual control over their respective territories. In the late 1920s, the Kuomintang, under Chiang Kai-shek, was able to reunify the country under its own control, moving the nation's capital to Nanking (Nanjing) and implementing "political tutelage", an intermediate stage of political development outlined in Sun Yat-sen's program for transforming China into a modern, democratic state. Effectively, political tutelage meant one-party rule by the Kuomintang.
The Second Sino-Japanese War (1937–1945) (part of World War II) forced an uneasy alliance between the Nationalists and the Communists as well as causing around 20 million Chinese civilian deaths. With the surrender of Japan in 1945, China emerged victorious but financially drained. The continued distrust between the Nationalists and the Communists led to the resumption of the Chinese Civil War. In 1947, constitutional rule was established, but because of the ongoing Civil War many provisions of the ROC constitution were never implemented in mainland China.
• Post Civil War (1949–present)
After its victory in the Chinese Civil War, the Communist Party of China (CPC) led by Mao Zedong gained control of most of Mainland China. On 1 October 1949, they established the People's Republic of China as a socialist state headed by a "Democratic Dictatorship" with the CPC as the ruling political party, thus, laying claim as the successor state of the ROC. The central government of the Chinese Nationalist Party led by Chiang Kai-shek retreated to the island of Taiwan that it had administered at the end of World War II, and moved the ROC government there. Major armed hostilities ceased in 1950 but no peace treaty has been signed.
