. The Islamic Resistance Movement, abbreviated Hamas (the Arabic acronym from Arabic: حركة المقاومة الإسلامية, romanized: Ḥarakat al-Muqāwamah al-ʾIslāmiyyah), is a Palestinian nationalist Sunni Islamist political organisation with a military wing, the Qassam Brigades. It has governed the Israeli-occupied Gaza Strip since 2007. . The Hamas movement was founded by Palestinian Islamic scholar Ahmed Yassin in 1987, after the outbreak of the First Intifada against the Israeli occupation. It emerged from his 1973 Mujama al-Islamiya Islamic charity affiliated with the Muslim Brotherhood.
