Samuel Cooke, known professionally as Sam Cooke, was an American singer and songwriter. Considered one of the most influential soul artists of all time, Cooke is commonly referred to as the "King of Soul" for his distinctive vocals, pioneering contributions to the genre, and significance in popular music. During his eight-year career, Cooke released 29 singles that charted in the Top 40 of the Billboard Pop Singles chart, as well as 20 singles in the Top Ten of Billboard's Black Singles chart. In 1964, Cooke was shot and killed by the manager of a motel in Los Angeles. After an inquest and investigation, the courts ruled Cooke's death to be a justifiable homicide. His family has since questioned the circumstances of his death. Cooke is included on Billboard's 2015 list of the 35 greatest R&B artists of all time.

Soul music is a popular music genre that originated in the African-American community throughout the United States in the late 1950s and early 1960s. It has its roots in African-American gospel music and rhythm and blues. Soul music became popular for dancing and listening, where U.S. record labels such as Motown, Atlantic and Stax were influential during the Civil Rights Movement. Soul also became popular around the world, directly influencing rock music and the music of Africa. It also had a resurgence in the mid-to late 1990s with the subgenre neo-soul, which added modern production elements and influence from hip-hop.
