European colonialism changed the world in countless ways, but the most blatantly apparent will always be the loss of life and bloodshed that occurred in the name of expansion and progress. Western imperialism, motivated by the desire to find resources, make money, save the "uncivilized," and garner prestige, ultimately brought about death, hardship, and violence for those who received it. The effects of colonialism - everything from genocide to resource exploitation to loss of cultural identity - are still felt today, while many of the lessons of colonialism seem to remain unlearned. Keep in mind, these are only some of the worst events and policies European imperialism had to offer. The horror, tragedy, and pain that was the Atlantic Slave Trade, well, that's a story for another list.
