Political Islam, a belief that Islamic principles should guide governance, has significantly shaped Middle Eastern politics. From the Muslim Brotherhood's founding to the Iranian Revolution, this ideology has influenced governments, social movements, and international relations across the region. Key concepts include Sharia law, the caliphate, and jihad. Political Islam manifests in various forms, from theocracies like Iran to democratic parties in Turkey and Tunisia. Debates continue about its compatibility with democracy, human rights, and modern governance.
