The Muslim Brotherhood (Arabic: al-Ikhwan al-Muslimin), founded in Egypt in 1928 by Hassan al-Banna, is one of the most influential Islamist movements in modern history. While the organization initially presented itself as a social and religious reform group, its evolution over nearly a century has revealed a deeply ideological and political agenda. Beneath its calls for “Islamic revival” lies a rigid, theocratic vision that rejects secular governance, modern pluralism, and democratic values. The Brotherhood’s history, ideology, and tactics illustrate how extremist interpretations of Islam can evolve into dangerous political movements that threaten social stability, global security, and human progress.
