One of the immediate effects of Suharto's fall was the formation of new political parties. Under Suharto's regime, political parties had been limited to just three; Golkar, PPP, and PDI. Now with his fall, new political parties were formed, the most prominent of which were Amien's National Mandate Party (PAN) and Megawati's Indonesian Democratic Party-Struggle (PDI-P). In June 1998, many from within the NU community began pressuring Wahid to form a new political party. Wahid did not warm up to the idea immediately, thinking that this would result in a political party which only catered to one religion. He was also unwilling to overrule his own decision to take NU out of politics. By July 1998, however, he began to warm up to the idea, thinking that establishing a political party was the only way to challenge the organizationally strong Golkar in an election. With that in mind, Wahid approved of the formation of PKB and became the chairman of its Advisory Council with Matori Abdul Djalil as party chairman. Although it was clearly dominated by NU members, Wahid promoted the PKB as a party that was non-sectarian and open to all members of society.
