The Islamic Resistance Movement, abbreviated Hamas , 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. In the 2006 Palestinian legislative election, Hamas secured a majority in the Palestinian Legislative Council by campaigning on promises of a corruption-free government and advocating for resistance as a means to liberate Palestine from Israeli occupation. In the Battle of Gaza, Hamas seized control of the Gaza Strip from rival Palestinian faction Fatah, and has since governed the territory separately from the Palestinian National Authority. After Hamas's takeover, Israel significantly intensified existing movement restrictions and imposed a complete blockade of the Gaza Strip. Egypt began its blockade of Gaza in 2007. This was followed by multiple wars with Israel, including those in 2008–09, 2012, 2014, 2021, and an ongoing one since 2023, which began with the 7 October Hamas-led attack on Israel.
Hamas has promoted Palestinian nationalism in an Islamic context. While initially seeking a state in all of former Mandatory Palestine it began acquiescing to 1967 borders in the agreements it signed with Fatah in 2005, 2006 and 2007. In 2017, Hamas released a new charter that supported a Palestinian state within the 1967 borders without recognizing Israel. Hamas's repeated offers of a truce (for a period of 10–100 years: 221–246 ) based on the 1967 borders are seen by many as consistent with a two-state solution, while others state that Hamas retains the long-term objective of establishing one state in former Mandatory Palestine.: 837, 839 While the 1988 Hamas charter was widely described as antisemitic, Hamas's 2017 charter removed the antisemitic language and said Hamas's struggle was with Zionists, not Jews. It has been debated whether the charter has reflected an actual change in policy.
In terms of foreign policy, Hamas has historically sought out relations with Egypt, Iran, Qatar, Saudi Arabia, Syria and Turkey; some of its relations have been impacted by the Arab Spring. Hamas and Israel have engaged in protracted armed conflict. Key aspects of the conflict include the Israeli occupation of the West Bank and Gaza Strip, the status of Jerusalem, Israeli settlements, borders, water rights, the permit regime, Palestinian freedom of movement, and the Palestinian right of return. Hamas has attacked Israeli civilians, including using suicide bombings, as well as launching rockets at Israeli cities. Australia, Canada, Paraguay, Israel, Japan, New Zealand, the United Kingdom, and the United States, as well as the European Union, have designated Hamas as a terrorist organization. In 2018 and 2023, a motion at the United Nations to condemn Hamas was rejected.
