Problem: 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.

Why did they do this?

Problem: Christopher Maurice Brown was born on May 5, 1989, in the small town of Tappahannock, Virginia, to Joyce Hawkins, a former day care center director, and Clinton Brown, a corrections officer at a local prison. He has an older sister, Lytrell Bundy, who works in a bank. Music was always present in Brown's life beginning in his childhood. He would listen to soul albums that his parents owned, and eventually began to show interest in the hip-hop scene.

In 2011, Brown began dating aspiring model Karrueche Tran. In October 2012, Brown announced that he ended his relationship with Tran because he did not "want to see her hurt over my friendship with Rihanna." The day after the announcement, Brown released a video entitled "The Real Chris Brown", which features images of himself, Tran, and Rihanna, as Brown wonders, "Is there such thing as loving two people? I don't know if it's possible, but I feel like that."  In January 2013, Rihanna confirmed that she and Brown had resumed their romantic relationship, stating, "It's different now. We don't have those types of arguments anymore. We talk about shit. We value each other. We know exactly what we have now, and we don't want to lose that." Speaking of Brown, Rihanna also said, "He's not the monster everybody thinks. He's a good person. He has a fantastic heart. He's giving and loving. And he's fun to be around. That's what I love about him - he always makes me laugh. All I want to do is laugh, really - and I do that with him." However, she also declared that she would walk away if Brown showed a hint of his past violent behavior towards her again. In a May 2013 interview, Brown stated that he and Rihanna had broken up again. He subsequently reunited with Tran, but they parted ways following confirmation of Brown's daughter with Nia Guzman in 2015.  In February 2017, Tran was granted a temporary 100-yard restraining order against Brown, and eventually a 5-year restraining order against the singer, claiming he threatened to kill her.
