​Established in 1931 as a puppet state of Japan, the Empire of Manchukuo was led by Pu Yi, the last Emperor of China, who reigned as Emperor Kang De. The state remained a loyal ally to Japan until 1945. In 1945, the Soviet Union declared war on Japan, and Manchukuo was subsequently invaded and abolished. The former puppet state was returned to communist China.[citation needed]
