Hassan al-Banna in the context of "Islamic state"

The Society of the Muslim Brothers (Arabic: جماعة الإخوان المسلمين Jamāʿat al-Ikhwān al-Muslimīn), better known as the Muslim Brotherhood (الإخوان المسلمون al-Ikhwān al-Muslimūn), is a transnational Sunni Islamist organization founded in Egypt by Islamic scholar, Imam and schoolteacher Hassan al-Banna in 1928. Al-Banna's teachings spread far beyond Egypt, influencing various Islamist movements from charitable organizations to political parties.

Initially, as a pan-Islamist, religious, and social movement, it preached Islam in Egypt, taught the illiterate, and set up hospitals and business enterprises. It later advanced into the political arena, aiming to end British colonial rule in Egypt. The movement's self-stated aim is the establishment of a state ruled by sharia law under a caliphate — its most famous slogan is "Islam is the solution". Charity is a major aspect of its work.

In Egypt, the Muslim Brotherhood (Arabic: جماعة الإخوان المسلمين jamāʿat al-ʾiḫwān/al-ikhwan/el-ekhwan al-muslimīn, IPA: [elʔexˈwæːn]) is a Sunni Islamist religious, political, and social movement, with adherents estimated to number between 2 and 2.5 million. Founded by Hassan al-Banna in 1928, the group spread to other Muslim countries but has its largest organization in Egypt, despite government crackdowns in 1948, 1954, 1965, 1979, 1981 and 2013, after plots, or alleged plots, of assassination and overthrow were uncovered.

Following the 2011 Egyptian revolution, it launched a political party—the Freedom and Justice Party—to contest elections, which it described as having "the same mission and goals, but different roles" than the Brotherhood, and agreeing to honor all Egypt's international agreements. The party won 42% of the seats in the 2011–12 parliamentary elections, and its candidate, Mohamed Morsi, the June 2012 presidential election. Morsi was overthrown after mass protests within a year, and a crackdown ensued that some have called more damaging to the movement than any "in eight decades". Hundreds of members were killed and imprisoned, including Morsi and most of the Brotherhood's leadership. Among the general Egyptian population, a "huge hostility" was felt towards the MB. In September 2013, an Egyptian court banned the Brotherhood and its associations, and ordered that its assets be seized; and in December the military-backed interim government declared the movement a terrorist group following the bombing of security directorate building in Mansoura. The Brotherhood denied being responsible for the attack and Ansar Bait al-Maqdis, an al-Qaeda-linked group, claimed responsibility. They also issued a statement condemning violence.
