Helen Folasade Adu was born on 16 January 1959 in Ibadan, Oyo State, Nigeria. Her middle name, Folasade, means "honour confers a crown". Her parents, Adebisi Adu, a Nigerian lecturer in economics of Yoruba background, and Anne Hayes, an English district nurse, met in London, married in 1955 and moved to Nigeria. Her parents separated, however, and Anne Hayes returned to England, taking four-year-old Sade and older brother Banji with her to live with their grandparents near Colchester, Essex.

After completing a three-year course work in fashion design, and later modeling briefly, Sade began backup singing with British band Pride. During this time, she formed a songwriting partnership with Pride's guitarist/saxophonist Stuart Matthewman; together, backed by Pride's rhythm section, they began doing their own sets at Pride gigs. Her solo performances of the song "Smooth Operator" attracted the attention of record companies, and in 1983 Sade and Matthewman split from Pride, along with keyboardist Andrew Hale, bassist Paul Denman and drummer Paul Cook, to form the band Sade. By the time she performed her first show at London's Heaven nightclub, she had become so popular that 1,000 people were turned away at the door. In May 1983, Sade performed their first US show at the Danceteria nightclub in New York City. On 18 October 1983, Sade Adu signed with Epic Records, while the rest of the band signed in 1984.  Following the record deal, the group began recording their debut album, Diamond Life, which took six weeks to record and was recorded entirely at The Power Plant in London. Diamond Life was released on 16 July 1984, reached number two in the UK Album Chart, sold over 1.2 million copies in the UK, and won the Brit Award for Best British Album in 1985. The album was also a hit internationally, reaching number one in several countries and the top ten in the US, where it has sold in excess of four million copies. Diamond Life had international sales of over six million copies, becoming one of the top-selling debut recordings of the '80s, and the best-selling debut ever by a British female vocalist.  "Your Love Is King" was released as the album's lead single on 25 February 1984 and was a success in European territories, charting at number seven in Ireland and number six on the UK Singles Chart. The song was less successful in the US, where it peaked at number 54 on the US Billboard Hot 100. The third single, "Smooth Operator", was released on 15 September 1984 and became the most successful song in the US from the album Diamond Life. The track peaked at number five on the US Billboard Hot 100 and the US Billboard Hot Black Singles, as well as peaking at number one on the US Billboard Adult Contemporary chart. In Europe the song fared well, peaking at number 19 in the UK, and reaching the top 20 in Austria, Switzerland, France and Germany.
