Overseas empire

Brazil’s independence in 1822 left Portugal’s overseas empire a largely African one, with scattered small holdings in Asia (in western India mainly Goa, Damão [now Daman], and Diu; East Timor in Indonesia; and Macau in South China). Beginning in 1836, Portugal pursued a policy of African territorial expansion and economic enhancement, concentrating first on Angola and later on Mozambique and Portuguese Guinea (now Guinea-Bissau). Portugal’s role in the European partition of Africa in the late 19th century was limited by its long-standing economic dependence on Great Britain. A colonial movement gained momentum in Lisbon, and a Portuguese scheme known as the “Rose-Coloured Map,” which laid claim to a colony stretching across Africa from Angola to Mozambique, was recognized by France and Germany in 1886. However, Britain challenged Portugal’s claim to territory in central Africa (in what are now Malawi and Zimbabwe) and issued an ultimatum, dated January 11, 1890, demanding the immediate withdrawal of Portuguese forces from the disputed regions. The ultimatum implicitly threatened, in the short run, the use of British naval force and, in the long run, an end to the venerable Anglo-Portuguese alliance, which dated from the late 14th century. The Lisbon government, obliged to comply, subsequently resigned. The ultimatum crisis rocked Portuguese public opinion, heightening imperial fever in the capital and principal towns, compromising the monarchy of King Charles I, and bolstering republicans.

Despite the failure of the central-corridor plan, Portugal retained a large African empire (about 8 percent of the continent). Two Anglo-Portuguese agreements—the 1891 boundary treaty and the so-called Windsor Treaty of October 14, 1899—safeguarded Portugal’s sovereignty over its existing colonies and reaffirmed the ancient alliance.

The rise of republicanism

During the period from 1890 to 1910, the relatively stable politics of rotating governments under the constitutional monarchy disintegrated. Feuding monarchist parties and politicians agreed that Portugal faced severe economic, financial, and social problems, but they quarreled over solutions. The republicans increased their support in Lisbon and the larger towns as well as in the rural south. In 1906 João Franco, a prominent politician with reformist plans for saving the monarchy, was appointed premier. Unable to unite the factious monarchists, he began to govern by decree. Franco boldly undertook to reform finance and administration but was accused of illegal money transfers to Charles. These scandals were followed by rumours of further intrigue, and on February 1, 1908, Charles and his heir, Louis Philip, were assassinated in an open carriage in the streets of Lisbon. Whether the regicides were isolated fanatics or agents of a hidden organization such as the Carbonária, a republican secret society, the killings were applauded by the republicans, who immediately began their preparations for a final attack on the monarchy.

Only age 18 at his accession, Charles’s younger son, King Manuel II (1908–10), was ill-equipped to solidify the crumbling monarchist factions. In the general elections of August 1910, both Lisbon and Porto voted in favour of a republic. On October 3 the murder by an insane patient of a leading republican figure, the distinguished psychiatrist Miguel Bombarda, offered the pretext for a rising that had already been organized. Armed civilians, soldiers, and the men aboard some ships in the Tagus, under the leadership of António Machado Santos, a key Carbonária figure, began the republican revolution on October 4; the next morning, Portugal’s First Republic was declared from the balcony of the Lisbon City Hall. Manuel escaped via his yacht to Gibraltar and then to England, where he remained in exile until his death in 1932.
