Jilin City
In 1949, Jilin province was smaller, encompassing only the environs of Changchun and Jilin City, and the capital was at Jilin City, while Changchun was a municipality independent from the province. In the 1950s, Jilin was expanded to its present borders. During the Cultural Revolution, Jilin was expanded again to include a part of Inner Mongolia, giving it a border with the independent state of Mongolia, though this was later reversed.
