input: Orr signed with Chicago, but his injuries limited him to only 26 games over the next three seasons. He sat out the entire 1977-78 season. By 1978, Orr had undergone over a dozen knee surgeries, was having trouble walking and barely skated anymore. However, in the summer of 1978, he decided to make a comeback. He played six games of the 1978-79 season and came to the conclusion that he could no longer play and informed the Black Hawks that he was retiring. He started a new role as an assistant to Chicago general manager Bob Pulford. He scored his last NHL goal and point against Detroit on October 28, 1978, at Detroit's Olympia Stadium.  Orr retired having scored 270 goals and 645 assists for 915 points in 657 games, adding 953 penalty minutes. At the time of his retirement, he was the leading defenceman in league history in goals, assists and points, tenth overall in assists and 19th in points. As of 2013, the only retired players in league history to have averaged more points per game than Orr are Wayne Gretzky, Mario Lemieux and Mike Bossy, all of them forwards. "Losing Bobby", said Gordie Howe, "was the greatest blow the National Hockey League has ever suffered".  The Hockey Hall of Fame waived the normal three-year waiting period for induction into the Hall and he was enshrined at age 31 - the youngest player living at the time of his induction in history. Orr was the eighth player to have the three-year period waived, the next two being Mario Lemieux (1997) and Wayne Gretzky (1999), after which the Hall decided that the waiting period would no longer be waived for any player except under "certain humanitarian circumstances".  His number 4 jersey was retired by the Bruins on January 9, 1979. At the ceremony, the crowd at Boston Garden would not stop applauding and as a result, most of the evening's program had to be scrapped at the last second due to the constant cheering. The crowd did not allow Orr to say his thank you speech until he put on a Bruins jersey. The day was proclaimed "Bobby Orr Day" in Boston and the event raised thousands of dollars for charity. He attended the Massachusetts Senate and House of Representatives and was given a five-minute standing ovation. Boston Celtics basketball superstar Larry Bird said in his pre-game inspiration that he always looked up at the rafters of the Garden at Orr's retired No. 4, instead of the retired numbers of Celtics stars such as Bill Russell, Bob Cousy, or John Havlicek.

Question: Isabella I (Spanish: Isabel, 22 April 1451 - 26 November 1504) reigned as Queen of Castile from 1474 until her death. Her marriage to Ferdinand II of Aragon became the basis for the political unification of Spain under their grandson, Charles I. After a struggle to claim her right to the throne, she reorganized the governmental system, brought the crime rate to the lowest it had been in years, and unburdened the kingdom of the enormous debt her brother had left behind.

Isabella received the title of Catholic Monarch by Pope Alexander VI, a pope of whose behavior and involvement in matters Isabella did not approve. Along with the physical unification of Spain, Isabella and Ferdinand embarked on a process of spiritual unification, trying to bring the country under one faith (Roman Catholicism). As part of this process, the Inquisition became institutionalised. After a Muslim uprising in 1499, and further troubles thereafter, the Treaty of Granada was broken in 1502, and Muslims were ordered to either become Christians or to leave. Isabella's confessor, Cisneros, was named Archbishop of Toledo. He was instrumental in a program of rehabilitation of the religious institutions of Spain, laying the groundwork for the later Counter-Reformation. As Chancellor, he exerted more and more power.  Isabella and her husband had created an empire and in later years were consumed with administration and politics; they were concerned with the succession and worked to link the Spanish crown to the other rulers in Europe. By early 1497, all the pieces seemed to be in place: The son and heir John, Prince of Asturias, married a Habsburg princess, Margaret of Austria, establishing the connection to the Habsburgs. The eldest daughter, Isabella of Aragon, married King Manuel I of Portugal, and the younger daughter, Joanna of Castile, was married to a Habsburg prince, Philip I of Habsburg.  However, Isabella's plans for her eldest two children did not work out. Her only son, John of Asturias, died shortly after his marriage. Her daughter Isabella of Aragon, whose son Miguel da Paz died at the age of two, died in childbirth. Queen Isabella I's crowns passed to her third child Joanna and her son-in-law, Philip I.  Isabella did, however, make successful dynastic matches for her three youngest daughters. The death of Isabella of Aragon created a necessity for Manuel I of Portugal to remarry, and Isabella's third daughter, Maria of Aragon, became his next bride. Isabella's youngest daughter, Catherine of Aragon, married England's Arthur, Prince of Wales, but his early death resulted in her being married to his younger brother, King Henry VIII of England.  Isabella officially withdrew from governmental affairs on September 14, 1504 and she died that same year on 26 November at the Medina del Campo Royal Palace. It is said that she had truly already been in decline since the death of her son Prince John of Asturias in 1497. She is entombed in Granada in the Capilla Real, which was built by her grandson, Charles V, Holy Roman Emperor (Carlos I of Spain), alongside her husband Ferdinand, her daughter Joanna and Joanna's husband Philip I; and Isabella's 2-year-old grandson, Miguel da Paz (the son of Isabella's daughter, also named Isabella, and King Manuel I of Portugal). The museum next to the Capilla Real holds her crown and scepter.
