The Western Sahara conflict
This is by far the longest enduring border conflict and modern quest for independence on the African continent. It is a conflict that has seen intermittent wars since 1970 between the Western Sahara nationalist group, Polisario Front, and Morocco.
While Morocco claims the land of Western Sahara belongs to the kingdom, Polisario has been defending the belief that Western Saharawis are a distinct nation.
The elaborate nature of this conflict has even drawn Mauritania into the violent melee at one point.
