Document 13: Purism (Spanish architecture): Purism is an initial phase of Renaissance architecture in Spain, which took place between 1530 and 1560, after to Isabelline Gothic and prior to the Herrerian architecture in the last third of the 16th century. The name "Prince Philip" refers to the period in which Philip II of Spain (born in 1527) had not yet received the inheritance of the Spanish Monarchy by abdication of his father the Emperor Charles V (1556). The name "Serlian" is due to the influential architect and treatise Sebastiano Serlio (in addition to the architectural element called "Serlian" in his honor). The Greco-Roman, the purist and the casticist are relate to the interpretation given to different elements of style, whether intellectual, formal, structural or decorative. Until then, writers of the period termed the classicist forms of the Italian Renaissance as the "roman" (Diego de Sagredo "Las Medidas del Romano", 1526), while the late-Gothic forms were called "the modern". For a more stylistic periodization more common in the art history, at that point of the 16th century the "Cinquecento" had entered in its Mannerist phase, while for the Spanish art is commonly used the expression High Renaissance (reserving the term Low Renaissance for the last third of the century).

Document 15: War of the Spanish Succession: The War of the Spanish Succession (1702–1714) was a major European conflict of the early 18th century, triggered by the death in 1700 of the last Habsburg King of Spain, the infirm and childless Charles II. Charles II had ruled over a vast global empire, and the question of who would succeed him had long troubled the governments of Europe. Attempts to solve the problem by peacefully partitioning the empire among the eligible candidates from the royal houses of France (Bourbon), Austria (Habsburg), and Bavaria (Wittelsbach) ultimately failed, and on his deathbed Charles II fixed the entire Spanish inheritance on his grandnephew Philip, Duke of Anjou, the second-eldest grandson of King Louis XIV of France. With Philip ruling in Spain, Louis XIV would secure great advantages for his dynasty, but some statesmen regarded a dominant House of Bourbon as a threat to European stability, jeopardising the balance of power.
