In 1894 relations were strained between the two states after Portugal granted refuge to Brazilian rebels after the "Revolta da Armada" incident. Portugal had sent a naval force constituted by the warships "Mindello" and "Affonso de Albuquerque" to Rio de Janeiro to protect Portuguese interests during the naval rebellion against President Floriano Peixoto. On 2 April 1894, the uprising was crushed and 493 rebels, including 70 officers and the mutiny leader, Admiral Luís Filipe de Saldanha da Gama, sought refuge on board the Portuguese warships. Despite protests from the Brazilian government, Portugal granted refuge to the rebels and sailed to the Rio de la Plata, where most of the refugees disembarked. The incident was regarded as a violation of Brazilian sovereignty and led Brazil to sever diplomatic relations with Portugal. Diplomatic relations were re-established in 1895 by the Prudente de Morais administration.
