History of Portugal (1834–1910)

The Kingdom of Portugal under the House of Braganza was a constitutional monarchy from the end of the Liberal Civil War in 1834 to the Republican Revolution of 1910. The initial turmoil of coups d'état perpetrated by the victorious generals of the Civil War was followed by an unstable parliamentary system of governmental "rotation" marked by the growth of the Portuguese Republican Party. This was caused mainly by the inefficiency of the Portuguese monarchy as well as their lack of interest in governing the country and acceptance of the 1890 British Ultimatum, which forced the abandonment of the colonialist Pink Map attempt to unite the colonies of Angola and Mozambique.

The situation culminated in a dictatorship-like government imposed by KingCarlos I, in the person of João Franco, followed by the king's assassination in the Lisbon regicide of 1908 and the revolution of 1910.
