The period of time when european imperialism greatly affected the continent of africa is called the
scramble for the congo
apartheid
scramble for africa
imperialism in africa

The correct answer is Scramble for Africa.

During the late 19th century, many European countries like England, France, Germany, Portugal, Spain, etc. were competing for control over different African countries. Many of these European countries were competing for African countries due to the natural resources available in these locations (like rubber in the Congo). Along with this, these countries were trying to spread their political power to other parts of the world in order to build global empires. Lastly, the competition for these territories was driven by the rapid industrialization taking place in Europe. European countries were producing more goods than ever before and wanted new markets to sell their goods.
