Background
Beginning in the late 1880s, Brazil's navy fell into obsolescence, a situation exacerbated by an
1889 coup d'état, which deposed Emperor
Dom Pedro II, and an
1893 civil war.
[Topliss, "The Brazilian Dreadnoughts," 240.][Livermore, "Battleship Diplomacy," 32.][Martins, "Colossos do mares," 75.] Despite having nearly three times the population of Argentina and almost five times the population of Chile,
[Scheina, "Brazil," 403.] by the end of the 19th century Brazil was lagging behind the Chilean and Argentine navies in quality and total tonnage.

The government of Brazil used some of the extra money from this economic growth to finance a naval building program in 1904,

battleship design, which debuted in December 1906 with the completion of
the namesake ship, rendered the Brazilian ships, and all other existing capital ships, obsolete.
[Topliss, "The Brazilian Dreadnoughts," 246.]
The money authorized for naval expansion was redirected by the new Minister of the Navy, Rear Admiral
Alexandrino Fario de Alencar, to building two dreadnoughts, with plans for a third dreadnought after the first was completed, two scout cruisers (which became the ), ten destroyers (the ), and three submarines.
[Scheina, ''Naval History'', 81.] The three battleships on which construction had just begun were scrapped beginning on 7 January 1907, and the design of the new dreadnoughts was approved by the Brazilians on 20 February 1907.
In South America, the ships came as a shock and kindled a
naval arms race among Brazil, Argentina, and Chile. The
1902 treaty between the latter two was canceled upon the Brazilian dreadnought order so both could be free to build their own dreadnoughts.

remarked that either ''Minas Geraes'' or ''São Paulo'' could destroy the entire Argentine and Chilean fleets.
[Martins, "Colossos do mares," 76.] In addition, Brazil's order meant that they had laid down a dreadnought before many of the other major maritime powers, such as Germany, France or Russia, and the two ships made Brazil the third country to have dreadnoughts under construction, behind the United Kingdom and the United States.
Newspapers and journals around the world, particularly in Britain and Germany, speculated that Brazil was acting as a proxy for a naval power which would take possession of the two dreadnoughts soon after completion, as they did not believe that a previously insignificant geopolitical power would contract for such powerful warships.
Despite this, the United States actively attempted to court Brazil as an ally; caught up in the spirit, U.S. naval journals began using terms like "Pan Americanism" and "Hemispheric Cooperation".

The ships were well-supplied with foodstuffs, ammunition, and coal, and the only demand of mutineers—led by
João Cândido Felisberto—was the abolition of "slavery as practiced by the Brazilian Navy". They objected to low pay, long hours, inadequate training, and punishments including ''bolo'' (being struck on the hand with a

Humiliated by the revolt, naval officers and the president of Brazil were staunchly opposed to amnesty, so they quickly began planning to assault the rebel ships.

Officers crewed some smaller warships and the cruiser , ''Bahia''s sister ship with ten 4.7-inch guns. They planned to attack on the morning of the 25th, when the government expected the mutineers would return to Guanabara Bay. When they did not return and the amnesty measure neared passage in the Chamber of Deputies, the order was rescinded. After the bill passed 125–23 and the president signed it into law, the mutineers stood down on the 26th.
During the revolt, the ships were noted by many observers to be well handled, despite a previous belief that the Brazilian Navy was incapable of effectively operating the ships even before being split by a rebellion. João Cândido Felisberto ordered all liquor thrown overboard, and discipline on the ships was recognized as exemplary. The 4.7-inch guns were often used for shots over the city, but the 12-inch guns were not, which led to a suspicion among the naval officers that the rebels were incapable of using the weapons. Later research and interviews indicate that ''Minas Geraes'' guns were fully operational, and while ''São Paulo''s could not be turned after salt water contaminated the
