Information: - The Nueva Planta decrees were a number of decrees signed between 1707 and 1716 by Philip Vthe first Bourbon King of Spainduring and shortly after the end of the War of the Spanish Succession by the Treaty of Utrecht. - The Crown of Castile was a medieval state 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 Leon 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 Catholic Monarchs is the joint title used in history for Queen Isabella I of Castile and King Ferdinand II of Aragon. They were both from the House of Trastamara and were second cousins, being both descended from John I of Castile; on marriage they were given a papal dispensation to deal with consanguinity by Sixtus IV. They married on October 19, 1469, in the city of Valladolid; Isabella was eighteen years old and Ferdinand a year younger; this marriage united both kingdoms under one crown. It is generally accepted by most scholars (John Elliott being an English-speaking example) that the unification of Spain can essentially be traced back to the marriage of Ferdinand and Isabella. Some newer historical opinions propose that under their rule, what later became Spain was still a union of two crowns rather than a unitary state, as to a large degree Castile and Aragon remained separate kingdoms, with most of their own separate institutions, for decades to come. The court of Ferdinand and Isabella was constantly on the move, in order to bolster local support for the crown from local feudal lords. - The Iberian Peninsula , also known as Iberia, is located in the southwest corner of Europe.
