Radical Islamism refers to a political and ideological movement that seeks to implement a strict interpretation of Islamic law (Sharia) in society. Proponents often believe that violence is a legitimate means to achieve their goals, which can include the establishment of an Islamic state or the overthrow of existing governments. This ideology is distinct from mainstream Islam, which encompasses a wide range of beliefs and practices. Radical Islamism has been associated with various extremist groups, such as Al-Qaeda and ISIS, which have carried out acts of terrorism to promote their agenda. These groups often exploit political, social, and economic grievances to recruit followers and justify their actions, leading to significant global security concerns.
