Problem: Barack Hussein Obama II ( ( listen); born August 4, 1961) is an American politician who served as the 44th President of the United States from 2009 to 2017. The first African American to assume the presidency, he was previously the junior United States Senator from Illinois from 2005 to 2008. Before that, he served in the Illinois State Senate from 1997 until 2004. Obama was born in 1961 in Honolulu, Hawaii, two years after the territory was admitted to the Union as the 50th state.

Obama was born on August 4, 1961, at Kapiolani Medical Center for Women and Children in Honolulu, Hawaii. He is the only President who was born in Hawaii and the only President who was born outside of the contiguous 48 states. He was born to a white mother and a black father. His mother, Ann Dunham (1942-1995), was born in Wichita, Kansas; she was mostly of English descent, with some German, Irish, Scottish, Swiss, and Welsh ancestry. His father, Barack Obama Sr. (1936-1982), was a married Luo Kenyan man from Nyang'oma Kogelo. Obama's parents met in 1960 in a Russian language class at the University of Hawaii at Manoa, where his father was a foreign student on scholarship. The couple married in Wailuku, Hawaii on February 2, 1961, six months before Obama was born. In late August 1961 (only a few weeks after he was born), Barack and his mother moved to the University of Washington in Seattle, where they lived for a year. During that time, the elder Obama completed his undergraduate degree in economics in Hawaii, graduating in June 1962. He then left to attend graduate school on a scholarship at Harvard University, where he earned an M.A. in economics. Obama's parents divorced in March 1964. Obama Sr. returned to Kenya in 1964, where he married for a third time. He visited his son in Hawaii only once, at Christmas time in 1971, before he was killed in an automobile accident in 1982, when Obama was 21 years old. Recalling his early childhood, Obama said, "That my father looked nothing like the people around me - that he was black as pitch, my mother white as milk - barely registered in my mind." He described his struggles as a young adult to reconcile social perceptions of his multiracial heritage. In 1963, Dunham met Lolo Soetoro at the University of Hawaii; he was an Indonesian East-West Center graduate student in geography. The couple married on Molokai on March 15, 1965. After two one-year extensions of his J-1 visa, Lolo returned to Indonesia in 1966. His wife and stepson followed sixteen months later in 1967. The family initially lived in a Menteng Dalam neighborhood in the Tebet subdistrict of south Jakarta. From 1970, they lived in a wealthier neighborhood in the Menteng subdistrict of central Jakarta.

Problem: Richard I (8 September 1157 - 6 April 1199) was King of England from 1189 until his death. He also ruled as Duke of Normandy, Aquitaine and Gascony, Lord of Cyprus, Count of Poitiers, Anjou, Maine, and Nantes, and was overlord of Brittany at various times during the same period. He was the third of five sons of King Henry II of England and Duchess Eleanor of Aquitaine. He was known as Richard Coeur de Lion or Richard the Lionheart because of his reputation as a great military leader and warrior.

Richard had already taken the cross as Count of Poitou in 1187. His father and Philip II had done so at Gisors on 21 January 1188 after receiving news of the fall of Jerusalem to Saladin. After Richard became king, he and Philip agreed to go on the Third Crusade, since each feared that during his absence the other might usurp his territories. Richard swore an oath to renounce his past wickedness in order to show himself worthy to take the cross. He started to raise and equip a new crusader army. He spent most of his father's treasury (filled with money raised by the Saladin tithe), raised taxes, and even agreed to free King William I of Scotland from his oath of subservience to Richard in exchange for 10,000 marks. To raise still more revenue he sold the right to hold official positions, lands, and other privileges to those interested in them. Those already appointed were forced to pay huge sums to retain their posts. William Longchamp, Bishop of Ely and the King's Chancellor, made a show of bidding PS3,000 to remain as Chancellor. He was apparently outbid by a certain Reginald the Italian, but that bid was refused. Richard made some final arrangements on the continent. He reconfirmed his father's appointment of William Fitz Ralph to the important post of seneschal of Normandy. In Anjou, Stephen of Tours was replaced as seneschal and temporarily imprisoned for fiscal mismanagement. Payn de Rochefort, an Angevin knight, was elevated to the post of seneschal of Anjou. In Poitou the ex-provost of Benon, Peter Bertin, was made seneschal, and finally in Gascony the household official Helie de La Celle was picked for the seneschalship there. After repositioning the part of his army he left behind to guard his French possessions, Richard finally set out on the crusade in summer 1190. (His delay was criticised by troubadours such as Bertran de Born.) He appointed as regents Hugh de Puiset, Bishop of Durham, and William de Mandeville, 3rd Earl of Essex--who soon died and was replaced by Richard's chancellor William Longchamp. Richard's brother John was not satisfied by this decision and started scheming against William. When Richard was raising funds for his crusade, he was said to declare, "I would have sold London if I could find a buyer".
