The Algerian Civil War, known in Algeria as the Black Decade, was a civil war fought between the Algerian government and various Islamist rebel groups from 11 January 1992 to 8 February 2002. The war began slowly, as it initially appeared the government had successfully crushed the Islamist movement, but armed groups emerged to declare jihad and by 1994, violence had reached such a level that it appeared the government might not be able to withstand it. By 1996–97, it had become clear that the Islamist resistance had lost its popular support, although fighting continued for several years after.

Islamism is a religio-political ideology. The advocates of Islamism, also known as "al-Islamiyyun", are dedicated to realizing their ideological interpretation of Islam within the context of the state or society. The majority of them are affiliated with Islamic institutions or social mobilization movements, often designated as "al-harakat al-Islamiyyah." Islamists emphasize the implementation of sharia, pan-Islamic political unity, the creation of Islamic states,, and rejection of non-Muslim influences—particularly Western or universal economic, military, political, social, or cultural.
