What did king francis of France die from?

Answer 1

Well, he had always been a very sick child, also he didn't grow properly, he was abnormally small for a boy, and his wife Mary Stuart who was Scottish, was actually very tall for a women. The reason he died was because of an ear infection, and due to his bad health, the infection infected his brains, which would have been the cause of death. (He probably wouldn't be able to have children anyway, since it was rumored that his balls did not drop.)

Answer 2

because of old age
