Sectarianism in Saudi Arabia is exemplified through the tensions with its Shi’ite population, who constitute up to 15% of the Saudi population. This includes the anti-Shi’ite policies and persecution of the Shi’ites by the Saudi government. According to Human Rights Watch, Shi’ites face marginalisation socially, politically, religiously, legally and economically, whilst facing discrimination in education and in the workplace. This history dates back to 1744, with the establishment of a coalition between the House of Saud and the Wahhabis, who equate Shi’ism with polytheism. Over the course of the twentieth century clashes and tensions unfolded between the Shi’ites and the Saudi regime, including the 1979 Qatif Uprising and the repercussions of the 1987 Makkah Incident. Though relations underwent a détente in the 1990s and the early 2000s, tensions rose again after the 2003 US-led election of Iraq (owing to a broader rise of Shi’ism in the region) and peaked during the Arab Spring. Sectarianism in Saudi Arabia has attracted widespread attention by Human Rights groups, including Human Rights Watch and Amnesty International, especially after the execution of Shi'ite cleric Nimr al-Nimr in 2016, who was active in the 2011 domestic protests. Despite Crown Prince Mohammed bin Salman's reforms, Shi’ites continue to face discrimination today.
