Battle of Boyacá Day is observed in Colombia every August 7 to commemorate the decisive battle that led to the country's independence from Spain in 1819. The battle occurred 150 km from Bogotá in the Andes Mountains, where a combined Republican army of Colombians, Venezuelans, and the British legion defeated the Royal army of Spain. This victory significantly weakened Spanish control in Latin America, contributing to the eventual creation of Gran Colombia. The day is a national holiday honoring those who fought for independence, and traditionally, a new president of Colombia assumes office on this date following national elections held every four years. Celebrations in Bogotá begin on August 6, coinciding with the city's foundation anniversary in 1583.
