A new predreadnought battleship, , was ordered under the new construction program in 1889. The advent of the 1891 Chilean Civil War had a breach between the two branches of the Chilean armed forces, while the bulk of navy sided with the congress side, the majority of the Chilean Army remained loyal to José Manuel Balmaceda. When the majority of the national congress broke relations with the government, Jorge Montt took control of the fleet at Valparaíso and with notable politicians, such as Ramón Barros Luco, on board, the fleet sailed north to the nitrate-rich Tarapacá area, which Chile had seized from Peru 10 years earlier. Tarapacá was, by that time, Chile's richest region in terms of natural resources and was without the fleet practically out of reach for the Chilean Army. From here, the navy organized an army made of nitrate miners, whom they armed and trained to face the 40,000-men-strong Army of Chile. In August 1891, the new army was disembarked in Quintero and defeated the Chilean Army at the Battle of Concón and the Battle of Placilla before the presidential faction disbanded and the congressional side took power. On the elections of October 1891, Jorge Montt was elected president.
