The war saw a confrontation between the Chilean Army and the Chilean Navy, which had sided with the president and the congress, respectively. This conflict ended with the defeat of the Chilean Army and the presidential forces and President Balmaceda committing suicide as a consequence. In Chilean historiography the war marks the end of the Liberal Republic and the beginning of the Parliamentary Era.
