Mujahideen

Mujahideen ( "") is the plural of mujahid (). Mujahid is the Arabic term for one engaged in "jihad" (literally, "struggle"). This term was first used to describe guerrilla-type militant groups led by the Islamist Afghan fighters in the Soviet–Afghan War. As of 2021, it is also used to described other jihadist groups in other countries. 
The English term "jihadists" is also related to the mujahideen.
