[2][3] His father, Raden Djamhad Wirantadidjaja, was a local village head, while his mother, Nyi Mas Taswi, was a female aristocrat.

[1] During his time in Cibatu, his name was changed from Samaun to Sanusi, as according to Yuda, it was too similar to the name of Semaun, the first chairman of the Communist Party of Indonesia.

[9] Back in Cibatu, he was raised by his older brother, Idris Hardjadinata, and entered the local Hollandsch-Inlandsche School (HIS).

However, Sanusi didn't stay long as he moved back to Bandung, with his teaching duties being substituted by future-major general Abdul Haris Nasution.

[3] The government remained in Garut for most of the revolution, with only a short stint in Tasikmalaya, after the signing of the Linggadjati Agreement, which ended after the Dutch launched Operation Product.

Several months later, on 25 July 1948, he was freed from prison on the condition that he must leave West Java and set for Yogyakarta, where the Republican government's capital was at the time.

There, Sanusi had to recover the war-torn Madiun Residency, which was devastated by the 1948 Communist rebellion, led by the People's Democratic Front.

[23] On 7 July 1951, Sanusi was officially inaugurated as Governor of West Java, replacing Sewaka, who was appointed Minister of Defense in the Sukiman Cabinet.

His appointment was initially challenged by the West Java Regional Representative Council (DPRD), specifically by the Masyumi Party.

Ensuring the security of Bandung and its surroundings against the threat of the Sekarmadji Maridjan Kartosuwiryo's Darul Islam rebellion.

He also checked himself the conditions of the Savoy Homann Bidakara and Prama Grand Preanger hotels, which were planned to be used to accommodate the delegates.

[32] After four years in Egypt, Sanusi submitted a request to the president to let him go back to Indonesia due to the worsening condition of his wife.

Due to this position, the Indonesian National Party began to adapt its ideology to make it closer to Marxism and communism.

On 4 August 1965, Sanusi, along with 150 other leaders of the party from different regions of Indonesia was dismissed after being accused as "fake marhaenists", capitalists, and feudalists.

Sanusi's solution wasn't accepted by both parties, and on 17 January 1975, Sunawar and Isnaeni stated their will to resign from their post.

Several days after seating the post of chairman, the former parties agreed to hold a congress as soon as possible, in the face of the upcoming election.

Sanusi was tasked with preparing the congress and further meetings by the CEC and the party's council was held in the house of Dr. Hasjim Ning.

The dualism of leadership inside PDI caused the external intervention of the government through the State Intelligence Coordinating Agency (BAKIN), which was represented by Ali Murtopo.

The agreement didn't solve the conflict, as was later known, that the reshuffle CEC had already formed new branches, causing dualism of leadership at the regional level.

The group held meetings in Pandaan to prepare a plan that would overthrow Sanusi, Isnaeni, and Sukowati from the party.

On one occasion, he also revealed that he was pressured by Suharto to sack Usep and Abdul Madjid, his colleagues, as the functionaries of the party.

On another occasion, he told one of his students, Eka Santosa, that since the conflict occurred, he was offered an amount of money and the position of commissioner in any government bank if he was willing to resign.

After his resignation from the party, Sanusi became more involved in the 1945 Institution for Constitution Awareness (Lembaga Kesadaran Berkonstitusi 1945, LKB 1945).

The organization was the main opposition to the Suharto regime, due to it being filled by former influential ministers and politicians in the Sukarno era.

The members of this organization then issued the Petition of Fifty on 5 May 1980, which criticized Suharto's compulsory instruction in the state philosophy, Pancasila.

Even so, the signatories formed the Petition of Fifty Working Group, based on Ali Sadikin's house.

The content of the petition was similar to the previous one, but this time, Sanusi was put as number one in the list of signatories, meaning that he officially opposed the government.

Due to his support to the petition, Sanusi was ignored and disrespected by several politicians and government officials in the events at the Gedung Sate.

At a quarter past midnight on 12 December 1995, Sanusi died after suffering complications in his lungs, kidney, and liver.

Sofiah was the daughter of Muhammad Abdullah Kusumah Atmadja, the head of a people's bank in Ciamis, commonly known as Juragan Ajun and Siti Rukayah.
