The main objective of thesis ''Narcoterrorism: Crossroads between drug trade and political violence'' is to describe and analyze the phenomenon of narcoterrorism, a concept that combines in its core the politically-motivated violence, the illicit drug trade, and the use of terrorist methods. The goal will be to establish a comprehensive theoretical framework for the various types of narcoterrorism and the different supportive types that may occur between the politically-motivated or ideological groups, and the drug-trafficking criminal groups. This framework will be later primarily tested on the case of Colombia, where various warring ideological and criminal groups will be observed and analyzed. Other cases that will be secondarily used to further prove the established assumptions, will be focusing on other countries which seen in recent history a surge of political or criminal violence, and are either manufacturing or trafficking illegal drugs. These will include Peru, Mexico, and Afghanistan. In the final section of the thesis, the theoretical framework will be assigned to real historical cases, and a question of the prerequisites of narcoterrorist emergence will be discussed.
