From 1974 to 1978, PAS joined the governing Barisan Nasional coalition, but has otherwise been in opposition at the federal level for the entirety of its history.
The 1980s saw the party taken over by a group of Muslim clerics ("ulama"), who shifted the party's ideology away from Malay nationalism towards a more radical brand of Islamism.
; formerly known as Malayan Islamic Party), commonly known as PAS, is an Islamist political party in Malaysia.
The formation of the party was the culmination of a growing movement among Muslim clerics within the United Malays National Organisation (UMNO) to formalise a discrete Islamic political organisation.
However, at first, the lines between UMNO and the new party were blurred.
The party was founded in 1951 by Muslim clerics in the United Malays National Organisation (UMNO).
In the party's early decades, it fused Islamist and Malay nationalist ideologies and entrenched itself as one of the country's strongest opposition parties.
PAS allowed dual membership of the two parties, and many of its early senior leaders were also UMNO members.
