Ancient Times:
- Biological warfare agents have been used since at least the 6th century BC when Assyrians poisoned wells during battles.
- In the 4th century BC, the Greeks defended the city of Plataea by using arrows soaked in pitch and fire.
Middle Ages:
- In the 14th century, the Mongols famously catapulted plague-infected corpses into the besieged city of Kaffa, leading to the spread of the Black Death throughout Europe.
- During the Thirty Years' War (1618-1648), the Swedes are believed to have used biological agents against enemy troops.
Modern Era:
- World War I saw the first state-sponsored use of chemical and biological warfare, primarily by the Germans.
- They used chlorine and mustard gas, but also experimented with pathogens like anthrax, glanders, and cholera.
- In response, the Allies established their own biological warfare research programs.
- World War II witnessed preparations for large-scale biological warfare, but no confirmed instances of deliberate deployment.
- Japan had a substantial biological weapons program, which included plans to spread plague, anthrax, and cholera across China and Southeast Asia.
- The United States also conducted bio-weapon research, developing plans for the aerial dissemination of anthrax, tularemia, and brucellosis.
- Post World War II:
- The Cold War era was characterized by extensive research, development, and stockpiling of biological weapons by both the United States and the Soviet Union.
- Though never deployed, these programs posed significant risks of accidental or unauthorized release.
Notable Biological Attacks:
- 1979: An anthrax release in a Soviet military facility near Sverdlovsk (now Yekaterinburg) resulted in at least 66 civilian deaths.
- 1984: Osho's disciples attempted a bioterror attack on the Dalles, Oregon, infecting salad bars in restaurants with Salmonella typhimurium, resulting in 751 reported cases of food poisoning.
- 2001: Letters containing anthrax spores were mailed to media outlets and politicians in the United States, resulting in the deaths of five people and multiple cases of inhalation anthrax. This incident is still under investigation, and the perpetrator remains unknown.
Biological Weapons Convention (BWC):
In response to the growing concerns about biological weapons, the BWC was established in 1975. This international treaty prohibits the development, production, and stockpiling of biological weapons. Biological weapons are defined as any microorganisms or toxins that can be used to cause death or disease with the intent to harm people, animals, or plants.
Challenges:
- Despite the BWC, concerns persist about the potential misuse of biotechnology and the risk of bioterrorism.
- Many countries still possess biological research facilities that may contribute to concerns in the event of an outbreak of unknown origin.
