Aguinaldo Boyacense in Tunja
Aguinaldo Boyacense is Tunja's flagship December Christmas festival, tracing back to a police officer's stunt of parading colleagues dressed as devils and matachines through the city's streets sometime between 1947 and 1956. The modern event centers on judged competitions for floats, comparsas, costumes and music, including the Navidades del Mundo parade reimagining global Christmas traditions.
Aguinaldo Boyacense grew out of a police officer's idea to dress colleagues as devils and matachines and parade them through Tunja's December streets, striking inflated pig bladders against the ground to startle onlookers in a play on older Christmas Eve traditions; accounts differ on whether that stunt happened in 1947 or 1956, but it is generally treated as the festival's origin point, with Carlos Julio Umana credited as the officer behind the idea.
