Bolivian Declaration of Independence
Bolivia's independence was definitively proclaimed on 6 August 1825 at a congress held in Chuquisaca. == Battle of Junín == While the Gran Colombian troops disembarked in the port of Callao under the command of General Antonio José de Sucre, General Andrés de Santa Cruz—who until a short time before had been fighting in the ranks of the realistas (Spanish loyalists)—arrived to share the libertarian ideas of José de San Martín and was sent to augment Sucre's troops, beginning their march toward Upper Peru.
