question: The Navarrese Civil War of 1451-1455 pitted John II of the Kingdom of Navarre against his son and heir-apparent, Charles IV. When the war started, John II had been King of Navarre since 1425 through his first wife, Blanche I of Navarre, who had married him in 1420. By the marriage pact of 1419, John and Blanche's eldest son was to succeed to Navarre on Blanche's death. When Blanche died in 1441, John retained the government of her lands and dispossessed his own eldest son, Charles , who was made Prince of Viana in 1423. John tried to assuage his son with the lieutenancy of Navarre, but his son's French upbringing and French allies, the Beaumonteses, brought the two into conflict. John was supported by the Agramonteses. From 1451 to 1455, they were engaged in open warfare in Navarre. Charles was defeated at the Battle of Aybar in 1452, captured, and released; and John tried to disinherit him by illegally naming his daughter Eleanor, who was married to Gaston IV of Foix, his successor. In 1451, John's new wife, Juana Enriquez, gave birth to a son, Ferdinand. In 1452, Charles fled his father first to France, where vainly sought allies, and later to the court of his uncle, John's elder brother, Alfonso V at Naples. Charles was popular in Spain and John was increasingly unpopular as he refused to recognise Charles as his "first born", probably planning to make Ferdinand his heir. The Navarrese Civil War presaged the Catalan Civil War of 1462-72, in which John's ill-treatment of Charles was a precipitating event.

question: Joanna la Beltraneja, born in 1462, the first and only daughter of King Henry IV of Castile, was of Asturias. A rumour spread that Princess Joanna was not actually the daughter of King Henry but rather of Beltran de la Cueva, the alleged lover of Queen Joan of Portugal. Joanna was thus nicknamed "la Beltraneja", as a mocking reference to her assumed father. Pressure from members of the nobility forced the King to strip her of the title and name his half-brother Alfonso as heir, in 1464. In 1465, a group of nobility assembled in Avila and overthrew King Henry, replacing him with Alfonso. That led to a war that ended in 1468 with the death of the 14-year-old Alfonso. Henry IV regained the throne, but the title of heir became disputed between Joanna, his daughter, and Isabella, his half-sister. That was resolved via the Treaty of the Bulls of Guisando, which gave Isabella succession rights but restricted her marriage options. Isabella secretly married Ferdinand in 1469 at the age of 17, ignoring Henry IV's wishes. Gradually, the couple gained a larger number of supporters and obtained a papal bull sanctioning their marriage from Pope Sixtus IV in 1472 and gained the support of the powerful Mendoza family in 1473. When Henry IV died in December 1474, both candidates for the throne were proclaimed Queen of Castile by their respective supporters. Aware of their position of weakness against Isabella's supporters, Joanna's supporters proposed for the 43-year-old King Afonso V of Portugal, a widower for some 20 years, to marry Joanna, his niece, and assume the throne of Castile with her.
Answer this question: How many years after being named heir did Alfonso replace Henry on the throne?
answer: 1

question: The Texans opened the 2006 season at home against the Philadelphia Eagles on September 10. The Texans looked sharp early with QB David Carr throwing a 25-yard TD pass to former Bills WR Eric Moulds in the 1st Quarter. The Eagles would tie the game with QB Donovan McNabb throwing a 42-yard TD strike to WR Donte' Stallworth. The Texans would retake the lead, however, after a 34-yard FG from K Kris Brown. Philadelphia took the lead late in the half with McNabb throwing a 5-yard TD pass to WR Reggie Brown and held on to it for the rest of the game.
