Jihadism is a neologism for modern, armed militant Islamic movements that seek to establish states based on Islamic principles. In a narrower sense, it refers to the belief that armed confrontation is an efficient and theologically legitimate method of socio-political change towards an Islamic system of governance. The term "jihadism" has been applied to various Islamic extremist or Islamist individuals and organizations with militant ideologies based on the classical Islamic notion of lesser jihad.
