History of biological warfare

Before the 20th century, the use of biological agents took three major forms: Deliberate contamination of food and water with poisonous or contagious material Use of microbes, biological toxins, animals, or plants (living or dead) in a weapon system Use of biologically inoculated fabrics and persons In the 20th century, sophisticated bacteriological and virological techniques allowed the production of significant stockpiles of weaponized bio-agents: Bacterial agents: Anthrax, Brucella, Tularemia, etc. Viral agents: Smallpox, Viral hemorrhagic fevers, etc. Toxins: Botulinum, Ricin, etc. The earliest documented incident of the intention to use biological weapons is possibly recorded in Hittite texts of 1500–1200 BC, in which victims of tularemia were driven into enemy lands, causing an epidemic. Although the Assyrians knew of ergot, a parasitic fungus of rye which produces ergotism when ingested, there is no evidence that they poisoned enemy wells with the fungus, as has been claimed. According to Homer's epic poems about the legendary Trojan War, the Iliad and the Odyssey, spears and arrows were tipped with poison. During the First Sacred War in Greece, in about 590 BC, Athens and the Amphictionic League poisoned the water supply of the besieged town of Kirrha (near Delphi) with the toxic plant hellebore. According to Herodotus, during the 4th century BC Scythian archers dipped their arrow tips into decomposing cadavers of humans and snakes or in blood mixed with manure, supposedly making them contaminated with dangerous bacterial agents like Clostridium perfringens and Clostridium tetani, and snake venom. In a naval battle against King Eumenes of Pergamon in 184 BC, Hannibal of Carthage had clay pots filled with venomous snakes and instructed his sailors to throw them onto the decks of enemy ships. The Roman commander Manius Aquillius poisoned the wells of besieged enemy cities in about 130 BC. In about AD 198, the Parthian city of Hatra (near Mosul, Iraq) repulsed the Roman army led by Septimius Severus by hurling clay pots filled with live scorpions at them.
