On 11 January 1992 senior military officers forced President Chadli Benjedid to resign; canceled the second round of legislative elections and annulled the results of the first round, which saw the opposition Islamic Salvation Front (FIS) achieve a major electoral victory; and imposed a year-long state of siege. Constitutional government was replaced by an army-dominated so-called Higher State Council responsive to no one but itself. In the weeks and months that followed further draconian measures were undertaken intended to subvert the incipient democratic process that Algeria had been experiencing in the several years following the deadly riots of October 1988. As part of the army's effort to regain control of state and society, it reined in the free-wheeling press, abolished the country's most popular political party (FIS), dissolved the National Assembly, and reimposed on civil society the apparatus of the omnipresent state security system (mukhabarat).
