Terrorism has its roots in the Latin word for "terror" and refers to intentional violence by non-state actors for political purposes. The root causes of terrorism include socio-economic factors like injustice, illiteracy, and unemployment, as well as cultural and ethnic tensions between groups that seek liberation from dominant states through sometimes violent means. Religious extremism, where groups impose their ideology through violence while claiming religious justification, also contributes to terrorism, though no religion actually condones killing innocents.
