Alexander The Great remains one of the most infamous and talked about figures in history. We know so much about his conquers around the world, but so little about what caused his death. There are many theories out there as to what brought this man to his downfall, but no one knows for sure. The most realistic theories of his death involve disease and viruses.
Malaria and Typhoid
Both of these diseases were common and rampant throughout Ancient Babylon, which would have made Alexander easily susceptible.
Transferred by mosquitoes, the symptoms of both malaria and typhoid are consistent with Alexander’s symptoms right before his death.
