The author often mentioned in his works that there is no inhabited territory in the world that is resistant to terrorism, while the roots of terrorism, surrounded by different motives and causes, go far back in history. Therefore, the author identifies terrorism as a world problem, which is never isolated in one environment, but very quickly, like a forest fire, spreads to other areas. In the era of rapid information and technological development, the concept of terrorism terrorism is becoming less and less precise and unambiguous as it is increasingly used. Given that we have seen in the not-so-distant past that terrorist organizations are unscrupulous in their attacks, one of the main concerns of modern times is undoubtedly the possibility of using biological weapons for terrorist purposes. This paper analyzes in detail the somewhat intimidating form of terrorism, known as bioterrorism, a distinction was made between this and other types of terrorism, and we have given a historical view of the use of biological weapons, all with the aim of more precisely defining this extremely complex phenomenon.
