of the blocks able to command a majority and push through the constitution it wanted, the assembly failed to agree and was dissolved by Sukarno in a decree on 5 July 1959 that also restored the original 1945 Constitution, which declared the state to be based on the Pancasila philosophy, not Islam. In 1960, President Sukarno banned Masyumi for alleged involvement in the Permesta rebellion. However, the leadership of NU saw the pro-poor Communist Party of Indonesia, which was close to Sukarno, as an obstacle to its ambitions, and competed with it to win support from the poor. Five years later, the coup attempt by the 30 September Movement took place. In 1965, the group took sides with the General Suharto-led army and was heavily involved in the mass killings of Indonesian communists. However, the NU later began to oppose Suharto's regime.

He formally apologized for NU's involvement in the events of 1965. He also stated that "Nadhatul Ulama (NU) is like Shiite minus Imamah; similarly Shiite is NU plus Imamah."

However, in 1973, it was obliged to "fuse" into the new United Development Party ().

As a result, in the 1987 election, the PPP vote collapsed from 28% in 1982 to only 16%. From then on, it was expected that the NU would concentrate on religious and social activities. Outside politics In 1984, the New Order government announced that all organizations would
