cabinet without Hasyim, the NU decided in principle to leave Masyumi. Three months later it withdrew all its members from Masyumi councils, and on 30 August it established the Indonesian League of Muslims, comprising the NU, PSSI and a number of smaller organizations. It was chaired by Hasyim. During the liberal democracy era (1950–1957), NU members served in a number of cabinet posts. In the first Ali Sastroamidjojo Cabinet, the NU held three seats, with Zainul Arifin appointed second deputy prime minister. However, following the fall of this cabinet, some NU members were opposed to the NU joining the new cabinet, to be formed by Burhanuddin Harahap Cabinet, believing that if he was unable to form a cabinet, the NU would be invited to try. It was finally pressured into participating, and was awarded the interior and religious affairs portfolios in the cabinet, which was sworn in on 12 August 1955.

On 2 March 1957, the Permesta rebellion broke out. Among its demands was the restoration of Mohammad Hatta to the vice-presidency. The NU supported these calls. Meanwhile, in the Constitutional Assembly, the NU joined Masyumi, the Indonesian Islamic Union Party (PSII), the Islamic Education Movement (Perti) and other parties to form the Islamic Block, which wanted Indonesian to become an Islamic state.
