History of Changchun
Early history
Changchun was initially established on imperial decree as a small trading post and frontier village during the reign of the Jiaqing Emperor in the Qing dynasty. Trading activities mainly involved furs and other natural products during this period. In 1800, the Jiaqing Emperor selected a small village on the east bank of the Yitong River and named it “Changchun Ting”.
At the end of 18th century peasants from overpopulated provinces such as Shandong and Hebei began to settle in the region. In 1889, the village was promoted into a city known as “Changchun Fu”.
Railway era
In May 1898, Changchun got its first railway station, located in Kuancheng, part of the railway from Harbin to Lüshun (the southern branch of the Chinese Eastern Railway), constructed by the Russian Empire.

After Russia’s loss of the southernmost section of this branch as a result of the Russo-Japanese War of 1904–1905, the Kuancheng station (Kuanchengtze, in contemporary spelling) became the last Russian station on this branch. The next station just a short distance to the south—the new “Japanese” Changchun station—became the first station of the South Manchuria Railway, which now owned all the tracks running farther south, to Lüshun, which they re-gauged to the standard gauge (after a short period of using the narrow Japanese 3 ft 6 in (1,067 mm) gauge during the war).
A special Russo-Japanese agreement of 1907 provided that Russian gauge tracks would continue from the “Russian” Kuancheng Station to the “Japanese” Changchun Station, and vice versa, tracks on the “gauge adapted by the South Manchuria Railway” (i.e. the standard gauge) would continue from Changchun Station to Kuancheng Station.
An epidemic of pneumonic plague occurred in surrounding Manchuria from 1910 to 1911. It was the worst-ever recorded outbreak of pneumonic plague which was spread through the Trans-Manchurian railway from the border trade port of Manzhouli. This turned out to be the beginning of the large pneumonic plague pandemic of Manchuria and Mongolia which ultimately claimed 60,000 victims.
