which european countries had arguadable the biggest empire in africa

Several European countries had significant colonial empires in Africa, but arguably the two that had the biggest empires were:

1. The United Kingdom: The British Empire at its peak was the largest empire in history and it controlled vast areas of Africa. The British established colonies and protectorates across the continent, with notable possessions including Egypt, Sudan, South Africa, Uganda, Kenya, Nigeria, Ghana (then the Gold Coast), Sierra Leone, and others.

2. France: The French Empire was the second largest colonial empire in Africa, with influence over countries including Algeria, Morocco, Tunisia, Senegal, Mali, Niger, Chad, the Central African Republic, Gabon, Djibouti, and Madagascar, among others.

Other significant colonial powers in Africa included Belgium, which controlled the Congo (now the Democratic Republic of the Congo); Portugal, with colonies such as Angola and Mozambique; Italy, with Libya and Somalia; and Germany, which had territories like Namibia (then German South-West Africa), Tanzania (then German East Africa), Cameroon, and Togo. However, their African holdings were smaller in comparison to those of the British and French empires.
