An industrialized economy meant new railways and telegrams that connected the nation, as well as factories in Buenos Aires. Argentina became one of the world's ten richest nations.
In terms of the military, the army was modernized, with new rifles and artillery. Argentina would confirm alliances with Peru, Bolivia, and Venezuela during the 1890s. Argentina would become a member of the Allied Coalition and ally with France and the United States in 1901. This meant that Argentina's enemy Brazil would join the London Pact, and the continent was divided between the two powers.
