Drug Barons of Colombia refer to some of the most notable drug lords which operate in illegal drug trafficking in Colombia. Several of them, notably Pablo Escobar, were long considered among the world's most dangerous and most wanted men by US intelligence. "Ruthless and immensely powerful", several political leaders, such as President Virgilio Barco Vargas, became convinced that the drug lords were becoming so powerful that they could oust the formal government and run the country.
The power of the Colombian drug barons took off in the 1970s and this resulted in a massive demand for cocaine in the United States and Europe.
In 1975, Pablo Escobar started developing his cocaine operation. He flew a plane himself several times, mainly between Colombia and Panama, in order to smuggle a load into the United States. When he later bought fifteen bigger airplanes (including a Learjet) and six helicopters, he decommissioned the original plane and hung it above the gate of his ranch at Hacienda Napoles. In May 1976, Escobar and several of his men were arrested and found in possession of 39 pounds (18 kg) of white paste after returning to Medellín with a heavy load from Ecuador. Initially Escobar tried to bribe the Medellín judges who were forming the case against him. After many months, the case was dropped. This was the beginning of his dealing with the authorities, using bribery or other means to achieve his goals.
Soon, the demand for cocaine was skyrocketing in the United States and Escobar organized more smuggling shipments, routes, and distribution networks in South Florida, California and other parts of the USA. The Medellín Cartel's massive wealth and power enabled them from the outset to bribe government and legal officials, and buy sophisticated weaponry for their protection. Escobar and Carlos Lehder worked together to develop a new island trans-shipment point in the Bahamas, called Norman's Cay. Lehder and Robert Vesco purchased most of the land on the island which included a 3,300 feet (1,000 m) airstrip, a harbor, hotel, houses, boats, aircraft; he even built a refrigerated warehouse to store the cocaine. From 1978 until 1982, the Cay was the Caribbean's main drug smuggling hub for the Medellín Cartel, as well as a tropical hideaway and playground for Lehder and associates. They flew cocaine in from Colombia by jet and then reloaded it into small aircraft. They then distributed it to locations in Georgia, Florida, and the Carolinas. Escobar was able to purchase the 7.7 square miles (20 km2) of land, which included Hacienda Napoles, for several million dollars. He created a zoo, a lake and other diversions for his family and organization. At one point, it was estimated that seventy to eighty tons of cocaine were being shipped from Colombia to the U.S. every month.
