5. in an attempt to avoid war among the major european powers over control of africa, european leaders met at the to divide up africa.

The answer is the Berlin Conference.

During the late 19th century, there was an increased interest by several European countries in colonizing Africa. This was due to Africa's strategic positioning and abundance of resources (like ivory and gold). To capitalize on these opportunities, countries like Portugal, Great Britain, France, and several others wanted the chance to colonize different parts of Africa. This is why the Berlin Conference was held, to make sure that there were rules/conditions for European countries trying to spread their political and economic influence into Africa.
