Oued Ed-Dahab Day, also known as Oued Ed-Dahab Allegiance Day, is observed in Morocco on August 14 every year. This public holiday commemorates the day Morocco regained control of the southern province of Oued Ed-Dahab from Mauritania. Oued Ed-Dahab-Lagouira is one of the sixteen regions of Morocco, situated within the disputed territory of Western Sahara. The historical context includes the Madrid Accords of 1975, which divided Western Sahara between Morocco and Mauritania, and the subsequent annexation of the territory by Morocco following a conflict with the Polisario Front. The day celebrates Morocco’s annexation of the southern third of Western Sahara, marking a significant moment in the region’s history.
