input: Elizabeth's mother made an alliance with Lady Margaret Beaufort, mother of Henry Tudor, later King Henry VII, who had the closest claim to the throne of those in the Lancastrian party. Although Henry Tudor was descended from King Edward III, his claim to the throne was weak, due to an act of parliament passed during the reign of Richard II in the 1390s, that barred accession to the throne to any heirs of the legitimised offspring of Henry's great-great-grandparents, John of Gaunt and Katherine Swynford. Despite this, his mother and Elizabeth Woodville agreed Henry should move to claim the throne and, once he had taken it, marry Elizabeth of York to unite the two rival houses. In December 1483, in the cathedral in Rennes, Henry Tudor swore an oath promising to marry her and began planning an invasion.  In 1484, Elizabeth of York and her sisters left Westminster Abbey and returned to court when Elizabeth Woodville was reconciled with Richard III, which may suggest that Elizabeth Woodville believed Richard III to be innocent of any possible role in the murder of her two sons (although this is unlikely owing to her involvement in Henry Tudor's failed invasion of October 1483). It was rumoured that Richard III intended to marry Elizabeth of York because his wife, Anne Neville, was dying and they had no surviving children. The Crowland Chronicle claimed that Richard III was forced to deny this unsavoury rumour. Soon after Anne Neville's death, Richard III sent Elizabeth away from court to the castle of Sheriff Hutton and opened negotiations with King John II of Portugal to marry his sister, Joan, Princess of Portugal, and to have Elizabeth marry their cousin, the future King Manuel I of Portugal.  On 7 August 1485, Henry Tudor and his army landed in Wales and began marching inland. On 22 August 1485, Henry Tudor and Richard III fought the Battle of Bosworth Field. Richard III, despite having the larger army, was betrayed by one of his most powerful retainers, William Stanley, and died in battle. Henry Tudor took the crown by right of conquest as Henry VII.

input: The whereabouts of McDaniel's Oscar are currently unknown. In 1992, Jet magazine reported that Howard University could not find it and alleged that it had disappeared during protests in the 1960s. In 1998, Howard University stated that it could find no written record of the Oscar having arrived at Howard. In 2007, an article in the Huffington Post repeated rumors that the Oscar had been cast into the Potomac River by angry civil rights protesters in the 1960s. The assertion reappeared in the Huffington Post under the same byline in 2009.  In 2010, Mo'Nique, the winner of the Academy Award for Best Supporting Actress, wearing a blue dress and gardenias in her hair, as McDaniel had at the ceremony in 1940, in her acceptance speech thanked McDaniel "for enduring all that she had to so that I would not have to". Her speech revived interest in the whereabouts of McDaniel's plaque. In 2011, J. Freedom duLac reported in the Washington Post that the plaque had disappeared in the 1960s.  In November 2011, W. B. Carter, of the George Washington University Law School, published the results of her year-and-a-half-long investigation into the Oscar's fate. Carter rejected claims that students had stolen the Oscar (and thrown it in the Potomac River) as wild speculation or fabrication that traded on long-perpetuated stereotypes of blacks. She questioned the sourcing of the Huffington Post stories. Instead, she argued that the Oscar was likely returned to Howard University's Channing Pollack Theater Collection between the spring of 1971 and the summer of 1973 or had possibly been boxed and stored in the drama department at that time. The reason for its removal, she argued, was not civil rights unrest but rather efforts to make room for a new generation of black performers. If neither the Oscar nor any paper trail of its ultimate destiny can be found at Howard today, she suggested, inadequate storage or record-keeping in a time of financial constraints and national turbulence may be blamed. She also suggested that a new generation of caretakers may have failed to realize the historic significance of the 5 1/2" x 6" plaque.

input: Christina Maria Aguilera was born in the Staten Island borough of New York City, New York, on December 18, 1980, to Shelly Loraine Kearns (nee Fidler), a musician, and Fausto Xavier Aguilera, a United States Army soldier. Her father is Ecuadorian, while her mother has German, Irish, Welsh, and Dutch ancestry. Her family moved frequently because of her father's military service, and lived in places including New Jersey, Texas, New York, and Japan. Aguilera and her mother alleged that her father was physically and emotionally abusive, claims which he denied; Aguilera used music as a form of escape from her turbulent household. Following her parents' divorce when she was six years old, Aguilera, her younger sister Rachel, and her mother (who later remarried Jim Kearns and gave birth to one more child, Michael 'Mikey' Kearns), moved into her grandmother's home in the Pittsburgh suburb of Rochester, Pennsylvania. After several years of being estranged, Aguilera expressed interest in reconciling with her father in 2012.  Growing up, Aguilera, known locally as "the little girl with the big voice", aspired to be a singer, singing in local talent shows and competitions. She won her first talent show at the age of 8, in which she performed Whitney Houston's "I Wanna Dance with Somebody (Who Loves Me)". In 1990, she appeared on Star Search singing "A Sunday Kind of Love", and was eliminated during the semi-final rounds. She later performed the same song during an appearance on Pittsburgh's KDKA-TV's Wake Up with Larry Richert. Throughout her youth in Pittsburgh, Aguilera sang "The Star-Spangled Banner" before Pittsburgh Penguins hockey, Pittsburgh Steelers football, and Pittsburgh Pirates baseball games, in addition to the 1992 Stanley Cup Finals. She attended Rochester Area School District in Rochester and Marshall Middle School near Wexford, and briefly attended North Allegheny Intermediate High School before being home schooled due to bullying.  In 1991, Aguilera auditioned for a position on The Mickey Mouse Club, although she did not meet its age requirements. She joined the television series two years later, where she performed musical numbers and sketch comedy until its cancellation in 1994. Her co-stars included Ryan Gosling, Keri Russell, Britney Spears, and Justin Timberlake. When she was fourteen, Aguilera recorded her first song, the duet "All I Wanna Do" with Japanese singer Keizo Nakanishi. She later sent her cover version of Houston's "Run to You" to Walt Disney Pictures in hopes of being selected to record the theme song "Reflection" for their animated film Mulan (1998). "Reflection" peaked at number 19 on the U.S. Billboard Adult Contemporary Chart.
