Despite his humble origins, Pablo Emilio Escobar Gaviria became the infamous leader of the Medellín cartel - responsible for 80% of the global cocaine market.
"El Patron," as he's often called, brought in an estimated $420 million a week in revenue, easily making him one of the wealthiest drug lords in history.
While verifying Escobar's wealth is impossible due to the nature of drug money, figures range up to $30 billion.
