The '''Treaty of the Bulls of Guisando''' ({{Langx|es|Tratado de los Toros de Guisando}}) is the name of a [[treaty]] agreed on top of the hill of Guisando near the [[Bulls of Guisando]] (located in [[Ávila (province)|Ávila]], [[Spain]]) on 19 September 1468, between [[Henry IV of Castile]] and his half-sister [[Isabella I of Castile|Isabella of Castile]].<ref>{{Cite book|last=Warren|first=Nancy Bradley|url=https://books.google.com/books?id=QsPBe83IWt0C&dq=1468+Toros+de+Guisando&pg=PA95|title=Women of God and Arms: Female Spirituality and Political Conflict, 1380-1600|date=2011|publisher=University of Pennsylvania Press|isbn=978-0-8122-0454-4|pages=95|language=en}}</ref><ref>{{Cite book|last=Rubin|first=Nancy|url=https://books.google.com/books?id=SW_BIgAACAAJ|title=Isabella of Castile: The First Renaissance Queen|date=1992|publisher=[[St. Martin's Press]]|isbn=978-0-312-08511-7|at=Chapters 8-9|language=en}}</ref><ref>{{Cite book|last=Williams|first=Patrick|url=https://books.google.com/books?id=umuoAwAAQBAJ&dq=1468+Toros+de+Guisando&pg=PT57|title=Katharine of Aragon: The Tragic Story of Henry VIII's First Unfortunate Wife|date=2013|publisher=Amberley Publishing Limited|isbn=978-1-4456-1880-7|language=en}}</ref> The treaty granted Isabella the title of [[Princess of Asturias]] and so she became heiress presumptive to the [[Crown of Castile]].
A civil war began in Castile in 1464 when a group of noblemen rebelled in an attempt to force the abdication of Henry IV. By 1465 they had symbolically dethroned the King and replace him with his half-brother [[Alfonso, Prince of Asturias (1453–1468)|Alfonso]]. With the death of Alfonso, in 1468, Isabella the half-sister of Henry IV, became the new candidate of the rebels. Rather than continuing the civil war, Isabella preferred to negotiate with Henry IV sending {{ill|Antonio de Veneris|es|Antonio Jacobo de Véneris}} as mediator.
After several meetings in [[Castronuevo]] a preliminary agreement was reached that would put an end to the civil war. The agreement was formalized in the Treaty of the Bulls of Guisando on 18 September 1468. With the treaty, the allegiance of the whole [[Kingdom of Castile]] was to return to the King and Isabella was to become his heiress presumptive, receive the title of Princess of Asturias as well as a large endowment. Isabella was to marry only with the consent of the King. Finally, [[Joanna la Beltraneja|Joanna]], the King's daughter, was removed from the line of succession to the throne through the annulment of Henry's marriage to his wife.
Later, the unapproved wedding of Isabella with [[Ferdinand II of Aragon|Ferdinand of Aragon]] caused Henry IV to shun the treaty. As a consequence the King recognized once more the rights of his daughter Joanna in a {{ill|Ceremony of Val de Lozoya|lt=ceremony|es|Ceremonia de la Val de Lozoya}} that took place in {{ill|Val de Lozoya|es|Valle del Lozoya}} on 25 November 1470. This was one of the events that eventually led to the [[War of the Castilian Succession]] a few years later.
