What were the different outcomes of European interactions with Africa, India and the Americas?European's had interaction with many countries such...

To me, the impact of Europeans on these areas were quite different.  The Americas came out the worst, especially in North America.  Africa was hurt badly by colonialism, but not as badly as the Americas.  India was relatively unharmed (but only relatively).

India came out pretty well because it was colonized by only a few Europeans with much of the work (even of governing) being done by Indians.  So the Indians kept their country and much self rule.

Africa was hurt badly by having so many people taken as slaves (West Africa) or by having people subjugated (South Africa).

North America's natives were essentially all killed, which is why I say the impact on them was the worst.
