context_page_description: The Crown of Castile was a medieval polity in the Iberian Peninsula that formed in 1230 as a result of the third and definitive union of the crowns and, some decades later, the parliaments of the kingdoms of Castile and León upon the accession of the then Castilian king, Ferdinand III, to the vacant Leonese throne. It continued to exist as a separate entity after the personal union in 1469 of the crowns of Castile and Aragon with the marriage of the Catholic Monarchs up to the promulgation of the Nueva Planta decrees by Philip V in 1715.
  The Indies, Islands and Mainland of the Ocean Sea were also a part of the Crown of Castile when transformed from lordships to kingdoms of the heirs of Castile in 1506, with the Treaty of Villafáfila, and upon the death of Ferdinand the Catholic.
  The title of "King of Castile" remained in use by the Habsburg rulers during the 16th and 17th centuries. Charles I was King of Aragon, Majorca, Valencia, and Sicily, and Count of Barcelona, Roussillon and Cerdagne, as well as King of Castile and León, 1516–1556.
context_section_description: In the previous kingdoms, positions in national institutions were filled by educated gentlemen. Philip II's administrators would normally come from either the University of Alcalá or the University of Salamanca. After Philip III the nobility once again asserted their right to govern the country. In order to show that there was a new order ruling there was a cleansing of the blood of Spain. Religious persecution led Philip to declare the expulsion of the Moriscos in 1609.
  Faced with the collapse of the Exchequer, in order to maintain the hegemony of Philip IV's Spanish Empire, the Count-Duke of Olivares, the king's favourite (valido) from 1621 to 1643, tried to introduce a series of reforms. Among these was the Unión de Armas, the creation of a new army of 140,000 reservists. Every territory within the kingdom contributed citizens proportionally in order to maintain the force. His aims of union did not work and the Spanish Crown continued as a confederation of kingdoms.
  Luis Méndez de Haro took over from Olivares as favourite Philip IV between 1659 and 1665. This was in order to alleviate interior conflicts sparked off by his predecessor (revolts in Portugal, Catalonia and Andalusia) and achieve peace in Europe.
  Upon the death of Philip IV in 1665, and with the incapacity of Charles II to govern, Spain suffered an economic slowdown and battles for power between the different 'favourites'. The death of Charles II in 1700 without descendants provoked the War of the Spanish Succession.
  After the war, all the territories were unified as a single country under the Crown of Spain.
