After more than a century of rule by France, Algerians fought through much of the 1950s to achieve independence in 1962. Algeria's primary political party, the National Liberation Front (FLN), was established in 1954 as part of the struggle for independence and has largely dominated politics since. The Government of Algeria in 1988 instituted a multi-party system in response to public unrest, but the surprising first round success of the Islamic Salvation Front (FIS) in the December 1991 balloting led the Algerian army to intervene and postpone the second round of elections to prevent what the secular elite feared would be an extremist-led government from assuming power. The army began a crackdown on the FIS that spurred FIS supporters to begin attacking government targets. Fighting escalated into an insurgency, which saw intense violence from 1992-98, resulting in over 100,000 deaths - many attributed to indiscriminate massacres of villagers by extremists. The government gained the upper hand by the late-1990s, and FIS's armed wing, the Islamic Salvation Army, disbanded in January 2000. Abdelaziz BOUTEFLIKA, with the backing of the military, won the presidency in 1999 in an election widely viewed as fraudulent and has won subsequent elections in 2004, 2009 and 2014. The government in 2011 introduced some political reforms in response to the Arab Spring, including lifting the 19-year-old state of emergency restrictions and increasing women's quotas for elected assemblies while also increasing subsidies to the populace. Algeria’s reliance on hydrocarbon revenues to finance the government and large subsidies for the population is under stress because of declining oil prices.
