Estado Novo (Portugal)
King Carlos I of Portugal confirmed colonial treaties of the 19th century that stabilized the situation in Portuguese Africa. These agreements were, however, unpopular in Portugal, where they were seen as being to the disadvantage of the country. In addition, Portugal was declared bankrupt twice—first on 14 June 1892 and again on 10 May 1902—causing industrial disturbances, socialist and republican antagonism, and press criticism of the monarchy. Carlos responded by appointing João Franco as Prime Minister and subsequently accepting Parliament's dissolution. In 1908, Carlos I was assassinated in Lisbon. The Portuguese monarchy lasted until 1910 when, through the 5 October revolution, it was overthrown and Portugal was proclaimed a republic. The overthrow of the Portuguese monarchy in 1910 led to a 16-year struggle to sustain parliamentary democracy under republicanism – the Portuguese First Republic (1910–1926).
Portuguese Empire
The loss of colonies was one of the reasons that contributed to the end of the personal union with Spain. In 1640 John IV was proclaimed King of Portugal and the Portuguese Restoration War began. Even before the war's final resolution, the crown established the Overseas Council, conceived in 1642 on the short-lived model of the Council of India (1604–1614), and established in 1643, it was the governing body for most of the Portuguese overseas empire. The exceptions were North Africa, Madeira, and the Azores. All correspondence concerning overseas possessions were funneled through the council. When the Portuguese court fled to Brazil in 1807, following the Napoleonic invasion of Iberia, Brazil was removed from the jurisdiction of the council. It made recommendations concerning personnel for the administrative, fiscal, and military, as well as bishops of overseas dioceses. A distinguished seventeenth-century member was Salvador de Sá.
In 1661 the Portuguese offered Bombay and Tangier to England as part of a dowry, and over the next hundred years the English gradually became the dominant trader in India, gradually excluding the trade of other powers. In 1668 Spain recognized the end of the Iberian Union and in exchange Portugal ceded Ceuta to the Spanish crown.
