Born on July 3, 1941 in the eastern city of Batna, Zeroual served in Algeria's National Liberation Army (FLN), which fought for independence from French rule.

After leading a transitional administration during a later civil war, Zeroual organised the country's first multi-party presidential election in 1995, winning by a wide margin.

In 1998, however, he unexpectedly cut short his five-year term, making way for Abdelaziz Bouteflika to succeed him and run the country for 20 years.

Zeroual remained respected in retirement. Algeria's presidency said he had died at a military hospital in Algiers after a serious illness and that flags would fly at half-mast across the country.
