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).

Meanwhile, Portugal became a county of the Kingdom of León and briefly during the independence of the Kingdom of Galicia in the 1060s and 1070s. It became an autonomous dominion of the Kingdom of León in 1128, emerging as a fully independent kingdom in 1139, officially recognized by the Treaty of Zamora in 1143. After this period, and with the rise of the Portuguese state after the beginning of the Age of Discovery, Portuguese architecture expanded under the patronage of the wealthy kings, nobility, powerful clergy and through the many battles with rivals such as Castile, the French and Dutch. During these periods, many of the prominent buildings were destroyed, rebuilt, re-purposed and closed on the whims of the monarchy, which progressively used architectural projects to support their power, remember past glories or expand their position in the Iberian peninsula.
