Lisbon Regicide
The assassination of King Carlos and the Prince Royal was the effective end of a constitutional monarchy in Portugal (later confirmed by the 5 October 1910 revolution). The regime functioned for another 33 months with growing agitation and demands for reform (although considerably less than in the future First Republic). It cannot be denied that the weak and permissive attitude in the Government of Acclamation was an incentive for the Republican Party to attempt another coup. The assassinations did not change the system of government; instead, they delayed the change.

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.
