Green March Day is observed in Morocco every November 6, commemorating the events of November 6, 1975, when approximately 350,000 unarmed Moroccans gathered in the city of Tarfaya. This public holiday marks Morocco's claim over the disputed territory of Western Sahara, which has been contested between Morocco and Mauritania. The demonstrators, carrying green banners symbolizing Islam, portraits of King Hassan II, and the Qur'an, crossed the border into Western Sahara, calling for the "Return of the Moroccan Sahara." The day signifies the beginning of Morocco's occupation of the territory, and it serves as a reminder of the historical claims and national identity associated with the region.
