Colonialism in Africa Helped Launch the HIV Epidemic a Century Ago is a very well-written article by Craig Timberg and Daniel Halperin from the Washington Post. I must say, I do not like reading 3-4 paged articles online; however, I thoroughly enjoyed this one. I could not stop reading it and I did not grow bored. This article documents how HIV began in a chimp, was transmitted to humans and then spread because of colonialism.
This article shows a negative aspect of colonialism, which I thoroughly enjoyed since colonialism seems to be heralded as a great achievement. In elementary/high school history classes, you touch upon the negative consequences of colonialism, but they are never really discussed. They are just a backdrop to the wonderful achievements of colonialism, like “manifest destiny,” “civilizing the uncivilized,” etc. However, colonialism had its effects- and not all of them were positive.
And tracing HIV to its origins during colonialism is one (of the many) negative effect(s).
