The history of Hamas is an account of the Palestinian nationalist and Islamist – described by some as fundamentalist – socio-political organization based in the Gaza Strip with an associated paramilitary force, the Ezzedeen al-Qassam Brigades. Hamas (حماس) Ḥamās is an acronym of حركة المقاومة الاسلامية Ḥarakat al-Muqāwamat al-Islāmiyyah, meaning "Islamic Resistance Movement".
Hamas was established during the First intifada against the Israeli occupation in 1987, and has its origins in Egypt's Muslim Brotherhood movement, which had been active in the Gaza Strip since the 1950s and gained influence through a network of mosques and various charitable and social organizations.
