メデジン・カルテル
On August 18, 1989, the Medellín Cartel assassinated the liberal presidential candidate Luis Carlos Galán. César Gaviria replaced him and was then elected president of Colombia. Gaviria avenged the death of Galan by dismantling the Medellín Cartel, but the gap left by this organization was quickly filled by the Cali Cartel and the FARC, which began expanding its influence and armed power in the countryside mainly.
