Absolute monarchy
Saudi Arabia

Saudi Arabia is an absolute monarchy, and according to the Basic Law of Saudi Arabia adopted by Royal Decree in 1992, the King must comply with Shari'a (Islamic law) and the Qur'an. The Qur'an and the body of the Sunnah (traditions of the Islamic prophet, Muhammad) are declared to be the Kingdom's Constitution, but no written modern constitution has ever been promulgated for Saudi Arabia, which remains the only Arab nation where no national elections have ever taken place since its founding. No political parties or national elections are permitted. The Saudi government is the world's most authoritarian regime in 2023 measured by the electoral democracy score of the V-Dem Democracy indices.
