Meaning
This flag stands for Western Sahara, a territory in northwest Africa that runs along the Atlantic coast. Most of the land is desert, with a long, thinly settled shoreline.
It appears mostly in geography quizzes, maps, news discussions and flag collections, and now and then in desert travel or photography posts with 🏜️. It is best used simply to name the place. “Next round of the map quiz: Western Sahara 🇪🇭🗺️”
