مجاهدین refers to individuals who engage in struggle or resistance, often in the context of fighting for a cause, particularly in Islamic contexts. The term is derived from the Arabic word "جهاد" (jihad), which means "struggle" or "striving." Historically, مجاهدین have been involved in various conflicts, including those against foreign occupation or oppressive regimes. One notable group associated with this term is the مجاهدین خلق (Mujahedin-e Khalq), an Iranian opposition organization that fought against the Shah of Iran and later against the Islamic Republic. They have been involved in various political and military activities since their formation in the 1960s, advocating for democracy and human rights in Iran.
