The campaign for the independence of New Granada, which included the crossing of the Andes mountain range, one of history's military feats, was consolidated with the victory at the Battle of Boyacá on 7 August 1819. The Battle of Boyacá (1819), was the decisive battle that ensured the success of Bolívar's campaign to liberate New Granada. The battle of Boyaca is considered the beginning of the independence of the North of South America, and is considered important because it led to the victories of the battle of Carabobo in Venezuela, Pichincha in Ecuador, and Junín and Ayacucho in Peru.
On August 7, 1998, Andrés Pastrana Arango was sworn in as the President of Colombia. A member of the Conservative Party, Pastrana defeated Liberal Party candidate Horacio Serpa in a run-off election marked by high voter turn-out and little political unrest. The new president's program was based on a commitment to bring about a peaceful resolution of Colombia's longstanding civil conflict and to cooperate fully with the United States to combat the trafficking of illegal drugs.
