Minas Geraes was a notable dreadnought battleship of the Brazilian Navy, representing a significant milestone in Brazil’s naval history. Laid down in April 1907 and launched at Newcastle-on-Tyne on 10 September 1908, the ship was the lead vessel of its class, reflecting cutting-edge battleship design at the time. It displaced approximately 12,000 tonnes and was powered by coal-oil-fired boilers, capable of reaching speeds around 19 knots. Its armament comprised twelve 10-inch (25 cm) guns arranged in six twin turrets, with a hexagonal configuration, and complemented by secondary guns and smaller AA weapons added during later refits. Construction was overseen by Armstrong Whitworth, with Minas Geraes being one of the earliest dreadnoughts built outside of the UK, which ignited a naval arms race in South America. After completion, the battleship traveled to the United States for fittings, including gunnery trials that confirmed its firepower and turret operation. It arrived in Brazil in April 1910, quickly becoming a symbol of national pride and modern naval power. Minas Geraes played a pivotal role in Brazil’s naval history, notably during the Revolt of the Lash in November 1910, where it was the focal point of a mutiny led by João Cândido, involving crew demands for better treatment and the abolition of flogging. The ship demonstrated disciplined handling during the revolt, which ended with the rebels’ demands being met. Throughout its service, Minas Geraes participated in various military and diplomatic missions, including visits to the United States and involvement in suppressing internal revolts. Refitted multiple times—most notably from 1921 to 1922—its modernization included updated fire-control systems, new rangefinders, and conversion from coal to oil fuel. During World War II, it served mainly as a stationary defense in Salvador, as it was too outdated for active combat. Decommissioned in 1952, Minas Geraes was sold for scrap in 1954 after over four decades of service, leaving a legacy as Brazil’s first dreadnought and a symbol of its naval ambitions during the early 20th century.
