The Northern Military Administration Office (Korean: 북로군정서) was an armed independence movement group founded in Donggandao in 1919. It originated from the Daejonggyo lineage. It was organized around Seo Il and Kim Jwa-jin in Jilin Province, Manchuria, in 1919. Based on the Junggwangdan organized by Koreans who immigrated to Bukgando, the Jeongjeongdan organized in Bukgando in 1919 was established by changing its name to Northern Military Administration Office. The Northern Military Administration Office established an officer training center to conduct military training and train independence fighters. In 1920, when Japan deployed its troops into Manchuria, it achieved a great victory over the Japanese army in the Battle of Cheongsanri.
