many countries continued to ship slaves across the atlantic ocean.
the united nations consistently waged war against rulers who they considered warlike.
political and ethnic rivalries within the countries emerged after independence

Political and ethnic rivalries within the countries emerged after independence, due in large part to the poor drawing of the former colonies' borders, which were drawn by their former imperial rulers.

The correct answer is Political and ethnic rivalries within the countries emerged after independence

When the countries were colonized, the borders were drawn in such a way that they ignored different ethnic or cultural groups. When those countries managed to win the fight for independence, they started fighting in civil wars because of various ethnic groups who claimed supremacy in those regions and wanted to rule. This led to a lot of instability.
