Liaoshen Campaign
The Manchu people conquered Shenyang in the 17th century and briefly used it as the capital of Qing-dynasty China. The Battle of Mukden took place in 1905 during the Russo-Japanese War. Japan's subsequent victory allowed Tokyo to annex the region west of the old city and to increase Japanese influence on Shenyang; in September 1931 the Mukden Incident led the Japanese to further invade and occupy the rest of Northeast China, forming the puppet state of Manchukuo. After the Japanese surrender in 1945, Shenyang remained a Kuomintang stronghold, but the Communists captured it in 1948 after the Liaoshen Campaign.
