These warships, the most powerful in the world, entered service at a time when dreadnoughts were an important factor in a nation's international prestige. The revolutionary design of the 1906 British warship HMS Dreadnought prompted the Brazilians to alter these plans and redirect their money into constructing three Minas Geraes-class dreadnoughts. Proponents of this plan believed that they needed a strong navy to become an international power and combat recent naval expansions in Argentina and Chile. In 1904, the Brazilian legislature allocated substantial funds to improve the country's naval forces. A naval arms race among Argentina, Brazil and Chile-the wealthiest and most powerful countries in South America-began in the early twentieth century when the Brazilian government ordered three dreadnoughts, formidable battleships whose capabilities far outstripped older vessels in the world's navies.
