Wahhabism is a fundamentalist and ultra-conservative branch of Sunni Islam that originated in the Arabian Peninsula in the 18th century. Followers of Wahhabism adhere strictly to the teachings of Muhammad ibn Abd al-Wahhab, the founder of the movement, and emphasize the literal interpretation of the Quran and Hadith.

Religious fundamentalism refers to the belief in the strict adherence to the basic principles of a religion, often characterized by a literal interpretation of religious texts, and a rejection of modern influences and interpretations. It often leads to a rigid and uncompromising belief system, with adherents seeing themselves as the only true followers of their faith.

Wahhabism has the most influence in Saudi Arabia, where it is the dominant form of Islam practiced by the government and many religious institutions. The strict interpretation of Wahhabism in Saudi Arabia has influenced the country's legal and social norms, and has played a role in shaping the country's politics and foreign policy.
