Ethiopia has acknolwledged that Menelick colonized the South, Southeast and Southwest nations. The inclusion of Article 39 in the present Ethiopian constitution, which Clown Abiy Ahmed continues to dishonor, for the Ethiopian nations to seek to determine their political future as colonized subjects is just.
"CONQUEST is the taking possession of a territory by force; COLONIZATION is the placement into a territory of settlers who are politically, economically, and militarily connected to their parent state. When joined, conquest and colonization involve the defeat of a people and the settling and ruling of its territory by its conquerors. Although seldom a concern for the conquerors, this sequence of events has usually had disastrous consequences for the conquered."
