Some context: 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.
What is the most important aspect of the later years?
A: Isabella did, however, make successful dynastic matches for her three youngest daughters.

Some context: The Strokes are an American rock band from New York City. Formed in 1998, the band is composed of singer Julian Casablancas, lead guitarist Nick Valensi, rhythm guitarist Albert Hammond Jr., bassist Nikolai Fraiture, and drummer Fabrizio Moretti. Following the conclusion of five-album deals with RCA and Rough Trade, the band has continued to release new music through Casablancas' Cult Records. Met with widespread critical acclaim, the Strokes' 2001 debut, Is This It, helped usher in the garage rock revival movement of the early-21st century--and ranks number eight on Rolling Stone's 100 Best Debut Albums of All Time, number two on Rolling Stone's 100 Best Albums of the '00s, 199 on Rolling Stone's 500 Greatest Albums of All Time and number four in the NME top 500 albums of all time.
The group began recording their follow-up in 2002 with producer Nigel Godrich (best known for his work with Radiohead), but later split with him in favor of Gordon Raphael, the producer of Is This It. Recordings with Godrich were never revealed. In August 2003, the band toured Japan, playing a couple of the upcoming songs: "Reptilia", "Meet Me In The Bathroom", "The Way It Is", "Between Love & Hate" (formerly known as "Ze Newie") and "12:51" (formerly known as "Supernova"). The band also played Paul Anka's "My Way" with Japanese lyrics. The Strokes released their second album Room on Fire in October 2003. It received praise from critics but was less commercially successful, although it still went gold. The album's sound maintained the Strokes' familiar reference points, while also evoking groups such as the Cars, Bob Marley, and Blondie. In the process, they made the cover of Spin Magazine for the second time, with each member receiving his own cover. They also made the cover of Rolling Stone for the first time. Additional media coverage of the band came from the relationship between Moretti and actress Drew Barrymore, which ended in January 2007. The first single taken from Room on Fire was the song "12:51", which used distinct keyboard-like sounds produced by Valensi's guitar. The video was also directed by Roman Coppola, and was inspired by the futuristic look of the 1980s film Tron. This consisted of a mainly black scene, with instances of glowing picton blue and riptide.  In November 2003, the Strokes played on Late Night with Conan O'Brien, performing "Reptilia", "What Ever Happened", "Under Control" and "I Can't Win". During the 2003/2004 "Room on Fire Tour", the band played with Kings of Leon as support act and Regina Spektor. While on tour, Spektor and the Strokes recorded the song "Modern Girls & Old Fashion Men", released as a B-side on the "Reptilia" single. Also during the tour, the band included the Clash's "Clampdown" as a cover, which was released as the B-side for "The End Has No End".  In late 2004, the Strokes revealed plans to release a live album. The Live in London LP was planned for release in October 2004, but was abandoned, reportedly due to recording quality problems. The chosen gig was one held at the legendary Alexandra Palace in North London.
