Explanation for SADR as I understand it: some tribes lived there with no official state until the Spanish colonialism, colonialism did what colonialism does then after the independence movements in the world from colonialism the polizario front was formed funded by gaddafi and algeria to fight Spanish colonialism, morocco came in the last moment with the green March as spain was leaving claiming the land as its (regular thing for morocco Google greater morocco to see how much they think is their land), morocco devided the land between it and Mauritania but this was fought against by the polizario front,Mauritania was defeated but morocco wasn't, morocco used napalm bombed civilians killed medics and sent civilians into the algerian desert where they still live,also built a wall with the help of Isr*el and apartheid south Africa, The war was put at a pause in 1991 but was continued in 2019 until now.

Morocco has no real claim over the sahara and foreign companies are stealing resources from the land, the people living there are living under apartheid military.

I might've forgotten something or two
