King's confidence in his abilities as a leader of men. He later commanded the gunboat Zarco and the corvettes Sagres and Estefânia, eventually rising to the top of his career as a naval officer in the Portuguese Royal Navy, having achieved the rank of Vice-Admiral (1895) and Major-General of the Armada (the highest rank of the Portuguese Royal Navy) before his retirement one year prior to his death in 1905. Colonial and diplomatic career The 1stCount of Paço d'Arcos had a notable colonial career throughout the Portuguese Empire, having reached its pinnacle as Governor-General of Portuguese India (1881). He was also Governor of Macao (1876–1879) and Mozambique (1880), as well as Portugal's first Ambassador to Brazil (1891–1893) after the former colony abolished the monarchy and sent Emperor Pedro II of Brazil of the House of Bragança into exile. This prestigious diplomatic post was fraught with difficulties as he represented to the new Brazilian republican government the reigning Portuguese House of Bragança which their ousted Emperor belonged to. In his diplomatic career he was also Minister Plenipotentiary to China, Japan and the Kingdom of Siam. Civil Governor of Lisbon As Governor of Lisbon in 1890 the Count of Paço d'Arcos was responsible for ordering the bloody police crackdown after days of rioting followed the issuing of the British Ultimatum regarding Portuguese colonies in Africa. The republican underground in Portugal seized the opportunity of the humiliating British Ultimatum to blame the monarchy and the King for Portugal's loss of prestige. After news of the Ultimatum and Portugal's concessions in Africa (present day Zimbabwe) reached the Portuguese people, Lisbon was thrown into a state of turmoil following massive rioting which threatened to bring down the regime. This was perhaps the first sign of what was to come when 18 years later King Carlos I and the Prince Royal Luis Fílipe were assassinated by members of the jacobin Carbonária in downtown Lisbon on February 1, 1908, eventually leading to the republican revolution of October 5, 1910. The Count of Paço d'Arcos, in his role as Governor and commander of the police in Lisbon, fulfilled his duty without hesitation, ordering the police to use force, which led to his vilification by the republican press of the time. Promotion to "Grande do Reino" Because of his service to the Crown, the Viscount of Paço d'Arcos was promoted in the Portuguese nobility to a Grandee of Portugal
