Sushen 2,300 years ago. They lived in the valley of the
Mudan River, and established the State of Mo (). During the
Tang dynasty,
Balhae established their Upper capital
Longquan Fu (Yongcheon bu) near
Lake Jingpo south of Mudanjiang around 755 AD. On January 14, 926, Yongcheon fell while Balhae was defeated by the
Khitans. Mudanjiang is named after the eponymous Mudan River (literally, "Peony River") flowing through it.
Imperial Russia built a train station for the
Chinese Eastern Railway in Mudanjiang in 1903, after which local development started boosting. Both Chinese and Russian settlers established themselves here. Mudanjiang was little more than a large village until the 1920s. By that time, Mudanjiang was strongly overshadowed by the nearby county town of
Ningan (Former
Ninguta). However, merchants from several countries including France, Russia, Britain and Denmark set up sub-agencies in Mudanjiang during this period, which led the trade area of the city to a rapid expansion. After the
Japanese invasion of Manchuria began on September 19, 1931, the whole
Manchuria was seized by Japan following the
Mukden Incident. Mudanjiang experienced a substantial growth in the 1930s under the Japanese occupation. Mudanjiang also became a military and administrative center going by the name Botankou, particularly after the railway from Tumen to Jiamusi was constructed in 1933. By that time several light industries including light engineering, lumbering, and food processing was established in the town. On December 1, 1937, Botankou City was established by the
Manchukuo government, administering five counties. On October 15, 1938, Japanese Government set up a consulate in Botankou and promoted Botankou as a municipality directly under the Manchukuo Government. As Manchukuo collapsed, Mudanjiang
was captured by the
Soviet Army on August 16, 1945. Mudanjiang was controlled by the Communist forces and became the capital of
Songjiang Province in 1948. However, after Songjiang Province was merged into Heilongjiang Province on June 19, 1954, Mudanjiang was reduced to a prefecture-level city. The historic
Beishan Stadium is located in the city. The 15,000-capacity stadium is used mostly for association football matches. ==Geography==
