Islamic terrorism is a form of religious terrorism carried out by fundamentalist militant Islamists and Islamic extremists with the aim of achieving various political or religious objectives, such as jihad.
Since at least the 1990s, Islamist terrorist incidents have occurred around the world and targeted both Muslims and non-Muslims. Most attacks have been concentrated in Muslim-majority countries, with studies finding 80–90% of terrorist victims to be Muslim. The annual number of fatalities from terrorist attacks grew sharply from 2011 to 2014, when it reached a peak of 33,438, before declining to 13,826 in 2019. From 1979 to April 2024, five Islamic extremist groups—the Taliban, Islamic State, Boko Haram, al-Shabaab, and al-Qaeda—were responsible for more than 80% of all victims of Islamist terrorist attacks. In some of the worst-affected Muslim-majority regions, these terrorists have been met by armed, independent resistance groups. Islamist terrorism has also been roundly condemned by prominent Islamic figures and groups.
