In the unstable period during and following the 1889 coup in Brazil, which deposed Emperor Dom Pedro II, and the 1893–94 navy revolt, the Brazilian Navy found itself unable to care for its own ships, let alone acquire new vessels. Meanwhile, Chile had agreed to a naval-limiting pact in 1902 with Brazil's principal rival, Argentina, as part of solving a larger boundary dispute, but they both retained the vessels built in the interim, many of which were significantly more modern and powerful than Brazil's ships. The Brazilian Navy was left behind its Argentine and Chilean counterparts in quantity as well—by the turn of the 20th century, Chile's total naval tonnage was , Argentina's , and Brazil's —even though Brazil had nearly three times the population of Argentina and almost five times that of Chile.
