Royal Palace of Évora
With King John II's death, in 1495, his cousin, Manuel I, Duke of Beja and Viseu, succeeded King John II as King Manuel I of Portugal. King Manuel I's personal monopoly on the spice trade allowed the King to be a great patron of the arts, constructing numerous palaces, convents, and churches throughout the country. King Manuel I took a great interest in Évora, establishing his court there on various occasions. From 1502 to 1520, King Manuel I ordered a vast series of renovations, constructions, and enlargements. During the Manueline Campaigns, as the works are collectively known as, the palace grew to one of the largest palaces in Iberia. Through architects Martim Lourenço, Álvaro Anes, and António de Lagoa the Manuline Campaign saw the construction of Couto Hall, the Wing of the Infantes, an infirmary, the Royal Gardens and Hunting Grounds, the Royal Library, and the Gallery of Dames, which is the only part of the palace to survive to present day. Alongside expansion of the palace, King Manuel I also renovated the existing parts of the palace, remodeling the Queen's Hall, the servants quarters, and the Rossio of the Palace. In 1519, King Manuel I ordered architect André Pires to turn the plain Hall of Ambassadors into a Manueline Throne Room, which would direct itself towards the Palace Rossio.
Carlos I of Portugal
Carlos became king on 19 October 1889. After the 1890 British Ultimatum, a series of colonial treaties were signed with the United Kingdom of Great Britain and Ireland. One signed in August 1890 defined African colonial borders along the Zambezi and Congo rivers, whereas another signed on 14 October 1899 confirmed colonial treaties of the 17th century. These treaties stabilised the political balance in Africa, ending Portuguese claims of sovereignty on the Pink Map, a geographical conception of how Portuguese colonies would appear on a map if the territory between the coastal colonies of Angola and Mozambique could be connected with territory in central Africa. These central African territories were taken over by Great Britain, however, a concession that was viewed as humiliating in Portugal. The agreements were thus looked upon as unpopular in Portugal and were felt to be disadvantageous to the country.
