From legal opposition to capital offense: The rise and fall of Syria's Muslim Brotherhood

In short: The Syrian Muslim Brotherhood once held seats in parliament, but a brutal cycle of secularist coups and militant insurgency transformed it into an underground movement. After the devastating Hama Massacre of 1982, the group was effectively broken as a domestic force, forcing its leadership into a long exile.

Mustafa al-Siba'i and Muhammad al-Mubarak al-Tayyib established the Syrian Muslim Brotherhood during the mid-1940s, when it first functioned as a lawful political body. It even won ten seats in the 1961 parliamentary elections. However, its trajectory shifted dramatically following the 1963 coup by the secularist Ba'ath Party. The new government banned the group and began a period of intense repression against Sunni Islamist movements, leading to the organization's radicalization as it moved into an armed struggle for power.

The conflict reached a violent climax between 1976 and 1982. During this era, the Brotherhood was split into two wings: a relatively moderate Damascus branch and a more militant Aleppo wing. The group engaged in assassinations and strikes against the Alawite-led government, culminating in the 1982 Hama uprising. In response, the military bombed the city of Hama—home to about 250,000 people—killing an estimated 10,000 to 30,000 residents. This 'Hama Massacre' effectively crushed the Brotherhood as a viable domestic political force and made membership in the group a capital offense under Law No. 49.

In the decades following its defeat, the group remained fragmented. While it attempted to regain relevance during the 2011 uprising, it struggled to connect with a younger generation that had grown up without its presence. By the mid-2010s, more radical Islamist groups overshadowed the Brotherhood's influence on the ground. Today, the organization remains primarily an exiled entity, led by Ali Sadreddine Al-Bayanouni in London, where it has adopted a reformist platform advocating for a pluralistic, democratic political system rather than the revolutionary violence of its past.
