When did biological warfare start?

in the 15 and 1600 the colonist gave small pox blankets to the indians.


But did people do that before then? I cannot believe they came up with that on their own.


Was it done in 1000? 1200? etc...

When did biological warfare start?
Biological warfare goes back much much farther than you think. In the 16th century B.C., Assyrians poisoned wells with ergot. During the 4th century B.C., Scythian archers covered arrow tips with animal feces so wounds would cause infection. In it's invasions, the Mongols catapulted their soldiers who died of the plague into the cities they were laying siege to so they would catch it too.
Reply:I hardly believe that the colonist did this on purpose....they probably just traded blankets for something else and their germs happened to be on them. I think the first use of biological warfare was World War I. That was when mustard gas and nerve gas were first used.
