The Saadian Dynasty was a Moroccan royal family that ruled from the early 16th century until the late 17th century. They are known for their significant contributions to Moroccan culture, architecture, and the arts, particularly during the reign of Sultan Ahmad al-Mansur. The dynasty emerged after the decline of the Alaouite Dynasty and played a crucial role in unifying Morocco. The Saadians are particularly famous for their architectural achievements, including the stunning Saadian Tombs in Marrakech. Their rule was marked by military successes, including the victory at the Battle of Ksar al-Kebir against the Portuguese. The dynasty eventually fell to the Alaouites, who continue to rule Morocco today.
