'europeans adopted uncivilosed ways to conquer africa' justify.
Answers
There were a number of ways in which European countries justified their imperialism.
Some of the justifications had to do with necessity. They argued that they needed to take an empire because they needed the resources from the places they imperialized. They argued that they needed empires so as to keep up with the other European countries. These justifications are based solely on need, not on the idea that imperialism was good for those who were colonized.
There was another strand of justification, though, that did argue that imperialism was good for the colonized. This can be best seen in Rudyard Kipling's poem "The White Man's Burden." In this view, the people who got colonized were lesser people who needed to be civilized and brought into the modern world. The idea was that imperialism was a positive good because it helped those people come out of their "backwardness" and become more like modern Europeans.
