Hamas is a militant and political Islamist group operating in the West Bank and Gaza. Hamas is designated as a terrorist organization by much of the international community but enjoys wide support from Palestinians as a legitimate force against Israel's occupation. The movement was founded as an offshoot of Egypt's Islamic Brotherhood, and in 1987 Hamas spiritual leader and founder Sheikh Ahmed Yassin established the movement's military wing, which became known as Hamas. In 1988, in the wake of the outbreak of the First Intifada, Hamas published its official charter, in which it announced its departure from nonviolence in its struggle against Israel.
