At least 40% of Moroccans are Amazigh who speak an Amazigh language as their mother tongue and are recognized as an official language in Morocco. The Sahrawi people are nomads with Arab and Amazigh ancestry who speak a dialect of Arabic known as Hassaniya that is more mutually intelligible with Peninsular dialects than elsewhere in the Maghreb. SADR recognizes Arabic and Spanish as official languages.
To me this is conflict is a left over of colonialism. Historically it and Mauritania and Morocco were part of the same realm with undefined borders and shifting alliances. Now either outcome is terrible. Rule under a corrupt Zionist puppet monarch, or half of Morocco a weak state of less than a quarter million people.
