In 1951, the Nepalese monarch ended the century-old system of rule by hereditary premiers and instituted a cabinet system of government. Reforms in 1990 established a multiparty democracy within the framework of a constitutional monarchy. A Maoist insurgency, launched in 1996, has gained traction and is threatening to bring down the regime, especially after a negotiated cease-fire between the Maoists and government forces broke down in August 2003. In 2001, the crown prince massacred ten members of the royal family, including the king and queen, and then took his own life. In October 2002, the new king dismissed the prime minister and his cabinet for "incompetence" after they dissolved the parliament and were subsequently unable to hold elections because of the ongoing insurgency. While stopping short of reestablishing parliament, the king in June 2004 reinstated the most recently elected prime minister who formed a four-party coalition government. Citing dissatisfaction with the government's lack of progress in addressing the Maoist insurgency, the king in February 2005 dissolved the government, declared a state of emergency, imprisoned party leaders, and assumed power.
