Following Iraqi president Saddam Hussein's Invasion of Kuwait in 1990, OIRAP shifted its tone considerably. Fearing Saddam's invasion of Saudi Arabia, "Saffar called on his followers to rally behind the government to fight Saddam’s regime. Many Saudi Shias volunteered to join the army and the civil defence force". OIRAP was dissolved, instead becoming the Reformative Movement in the Arabian Peninsula in 1991. This new Reform Movement called for peaceful reform and democracy, using petitions first and foremost to improve the status of Saudi Shi'ites and their working conditions and salaries within the oil sector. Relations between the regime and the Shi'ites became more accommodating. In 1993 King Fahd agreed to "release 400 Shias held as political prisoners and allow 1,200 to 1,500 others to return to the Kingdom". The Reform Movement formally dissolved, as a result of its negotiations with King Fahd. A particularly significant development occurred when the Saudi regime referred to Shi'ism as a heterodox sect in a reissued school text, recognising Shi'ite Islam as having its own school of jurisprudence.
