[2][3] After the Battle of Cheongsanri in 1920, the independence movement in Manchuria and Primorsky Krai was dispersed and stagnated due to the Japanese army's Gando Massacre and the Free City Incident.

As a result of holding a unified conference in Liuhe County, the Righteous Government, an independence movement federation, was created in November 1924.

[4] In July of the same year, Lee Sang-ryong, an official of the Bureau of Justice and Military Prefecture, was appointed to the State Council of the Shanghai Provisional Government, and a coalition cabinet centered on the anti-Japanese independence movement groups in Manchuria was established.

However, the Manchurian independence movement, which did not highly evaluate the provisional government, As the sculpture failed due to groups' refusal to take office, Lee Sang-ryong resigned from his position as head of state in February of the following year.

From this time on, the Righteous Government took into account the realistic conditions of independence movement groups, refrained from military action, and focused on promoting food production and industry.

[4] Jeong Yi-hyeong, Yang Gi-tak, Hyeon Jeong-gyeong, and Oh Dong-jin, who were participating in the Righteous Government, agreed that a core group was needed to systematically lead the independence movement.

In the end, members of the nationalist camp continued to defect from the party, and Joo Jin-soo and Lee Kyu-poong returned to the Soviet Union.

By December of the following year, 15 key executives, including Oh Dong-jin, chairman of the Military Committee of the Righteous Government Jeong I-hyeong, and Lee Dong-gu, were caught by the Japanese police and were disbanded.

The Jeonman Unification Association said:[1] In March 1925, the Righteous Government established a central organization in Samwonpo, Yuha-hyeon with a system of separation of three powers (legislation, judiciary, and administration).

Those who supported the provisional government broke away from the Tonguibu, one of the organizations that formed the Bureau of Justice and Military Prefecture, and formed the Army Advisory Office, and there was a conflict over the issue of support for the provisional government in the Jeonman Unification Association, which gathered to organize the Bureau of Justice and Military Prefecture.

Accordingly, some of the Bureau of Justice and Military Prefecture criticized Lee Sang-ryong's inauguration of the Provisional Government's State Council, and this difference of opinion led to the disintegration of the Central Administrative Committee and the Central Council of the Bureau of Justice and Military Prefecture due to a vote of no confidence in each other.

The County Citizens' Representative Council revised and promulgated the Bureau of Justice and Military Prefecture Charter and elected new central administrative members.

It had jurisdiction over Koreans residing in about 40 counties south of Harbin and carried out civil affairs activities to support their livelihoods.

[2] The Righteous Government established local organizations in Tonghua, Hwanin, Gwanjeon, Jian, Linjiang, Jangbaek, and Yuha County.

In particular, after the formation of the Military and People's Representative Council in January 1926, it actively carried out guerrilla warfare into the country and destruction of Japanese ruling institutions in Manchuria.

Based on this military organization, the Righteous Government Volunteer Army entered the country and carried out armed activities, waging guerrilla warfare.

The Bureau of Justice and Military Prefecture participated in the national unity party movement that began in early 1927, and most of the members were based in southern Manchuria.

In addition, trade unions were established in rural areas so that Koreans could develop industries in the spirit of mutual assistance.

[3] the Bureau of Justice and Military Prefecture focused on improving the unstable economic situation of Koreans living in Manchuria from the beginning of its establishment.

With an organization like the Righteous Government, the most important thing that was focused on for Koreans under the jurisdiction was industrial revival activities for the survival of the people.

They promoted the compilation of textbooks to be used in schools and also resolved to reform the education system and expand schools.As part of the journalistic activities and media activities to promote national consciousness, he published newspapers such as the "Righteous Government Gazette", "Central News Agency", "Daedong Minbo", and "Xinhua Minbo", as well as the magazine "Comrades".

[4] Afterwards, in February 1928, the executives of the Righteous Government, the General Staff Headquarters, and the Korean People's Association in Manchuria gathered at Ningguta (寧古塔, present-day Ning'an) and decided to hold a meeting of developing the national unity party movement.

[4] Then, in May, 39 representatives of 18 independence movement groups in Manchuria gathered in Panshi County, Jilin Province to discuss the issue of forming a single party.

[4] Afterwards, the Righteous Government, the central force in the council, launched an unification movement with the General Staff Headquarters and the Korean People's Association in Manchuria, but failed to achieve complete integration.
