Raja Junjungan Lubis

On 28 October 1971, Lubis was inaugurated as the member of the People's Representative Council, representing South Tapanuli. The term of the council ended on 1 October 1977.

As Lubis was politically independent, Lubis was opposed by the Indonesian Communist Party. The party held rallies and demonstrations to remove non-leftist civil employees and government apparatus. The rallies and demonstration culminated in the demonstration to oust Lubis from his office. As the demonstration became bigger, the central government took action by removing Lubis from office on 25 April 1963. He was replaced by acting governor Eny Karim.

On 1 April 1960, Lubis was inaugurated as the Governor of North Sumatra, replacing Zainal Abidin.

After the Indonesian National Revolution ended, Lubis was appointed by the governor of North Sumatra as the Regent of South Tapanuli — consisting of Angkola Sipirok, Padang Lawas, Mandailing Natal — in 1951. During his term, he created 6 new subdistricts in South Tapanuli. On 1 February 1954, he was transferred by governor Sutan Mohammad Amin Nasution to Central Tapanuli, and became the Regent of Central Tapanuli. As the Regent of Central Tapanuli, he also concurrently assumed the office as the Mayor of Sibolga — the capital of Central Tapanuli — on 11 February 1954. He resigned as the Mayor of Sibolga on 31 December 1957, and resigned as the Regent of Central Tapanuli on 1 August 1958.

During the Indonesian National Revolution, Lubis was appointed as the member of the People's Representative Council of Sumatra, representing Tapanuli. The council was inaugurated on 17 April 1946, and was dissolved after the members of the People's Representative Council of North Sumatra was formed on 13 December 1948. Lubis also concurrently held the office as the Regent of Batanggadis from 30 August 1947 until 12 December 1949. He was also appointed as the Chief of Staff for Civilian Affairs in 1949, and on 16 August 1949, he was appointed as the coordinator for civilian affairs in Tapanuli. After his resignation as the Regent of Batanggadis, his office was replaced by Fachruddin Nasution, and he became the Deputy Military Governor of Tapanuli and East Sumatra. As the deputy governor, he was involved in negotiations between the Dutch and Indonesian and was involved in settling the conflicts between rogue warriors in North Sumatra.

After the surrender of Japan on 15 August 1945 and the proclamation of Indonesian Independence on 17 August 1945, on 24 August 1945, the Japanese forces in Mandailing Natal declared that World War II has ended. Although the Japanese did not mention any references to the proclamation of independence, several people in Mandailing Natal began to spread rumor about the proclamation after the return of a Heiho member from Java. Lubis, as the number one official in Mandailing Natal, decided to form a body to investigate the truth of the rumor on 8 September 1945. Hamzah Lubis was sent by Junjungan Lubis to Bukittinggi to meet M. Syafei and Adinegoro about the truth of the rumor. Ayub Sulaeman, the secretary of Padangsidempuan, received a wire from Adnan Kapau Gani about the proclamation. Hamzah Lubis would return on 12 September 1945, bringing copies of the Constitution of Indonesia, law about the Indonesian National Committee, and the text of the proclamation of Indonesian Independence.

Junjungan Lubis, as the chairman of the Regional Defense Council of Mandailing Natal, invited other members of the council to discuss the best way to announce the proclamation to the people and enact the law about the Indonesian National Committee. It was decided that the proclamation text would be copied and spread to the whole Mandailing Natal. To execute this decision, the youth members of the council was tasked to spread the text with bicycle or on foot. Another decision was to organize a mass meeting to announce the proclamation directly to the people. The Japanese forces attempted to prevent this mass meeting, but failed. On 3 October 1945, the mass meeting was finally held, and was attended by Mandailing Natal populace from cities and villages. After the mass meeting, the Regional Defense Council was changed into the Republic of Indonesia Youth.

On 12 September 1945, Junjungan Lubis, Kari Oesman, and Fachruddin Nasution departed from Padangsidempuan to Tarutung. Junjungan Lubis, along with other delegates, appointed Abdul Hakim Harahap as the formateur of the Indonesian National Committee of Tapanuli. Junjungan Lubis became the member of the Indonesian National Committee of Tapanuli.

During the Japanese occupation of the Dutch East Indies, Lubis was appointed as the chairman of the Regional Defense Council of Mandailing Natal in 1943. In 1945, he was appointed as the Chairman of the Mandailing Natal branch of the Hōkōkai, a Japanese-oriented organization. In the same year, he was appointed as the member of the Syu Sangi Kai (advisory council) of Tapanuli. Later on, he was promoted and became the Assistant Resident of Mandailing Natal, the highest office in Mandailing Natal.

Lubis began his career as the chief of the Ulu Pungkut village in Huta Godang from 1924 until 1945. During this period, he also participated in matters pretraining to Tapanuli traditions. He became the chair of the Bona Bulu Sahat (Our Hometown), a customary institution, in 1939. He also joined the Kerapatan Adat Tapanuli (Tapanuli Customary Institution) in 1941 as its chair, and on the same year he also joined the Tapanuli Customary Commission in Padangsidempuan as a central member.
