The history of Changchun is relatively short but packed with events that transformed it from a small settlement into a major industrial and administrative hub. The city was officially founded in 1800, initially as a small trading post at a crossroads. Its location in the center of the fertile Manchurian Plain facilitated its gradual growth as a center for agricultural trade, particularly in soybeans.
A key factor that determined Changchun's destiny was the construction of the Chinese Eastern Railway (CER) in the late 19th and early 20th centuries. The laying of the railway line turned the city into a strategically important transport hub connecting various parts of the region. This attracted the attention of foreign powers and contributed to rapid economic development. The city became the junction where the South Manchuria Railway and the Chinese Eastern Railway met, making it a center for logistics and commerce.
A new chapter in the city's history began in the 1930s. From 1932 to 1945, Changchun, renamed Xinjing (meaning "New Capital"), served as the capital of the state of Manchukuo. During this period, large-scale urban planning was implemented, which still defines the modern structure of Changchun's central districts. Numerous administrative buildings were erected, and wide avenues and squares were created, giving the city a metropolitan appearance. The economy was focused on industry and resource processing, laying the foundation for Changchun's future transformation into the "Chinese Detroit"—a center of automotive manufacturing.
