The Black Eyed Peas date back to 1988, when eighth-graders william Adams (will.i.am) and Allan Pineda (apl.de.ap) met and began rapping and performing together around Los Angeles. The pair signed to Ruthless Records (run by Eazy-E) in 1992, catching the attention of Eazy-E manager Jerry Heller's nephew. Along with another friend of theirs, Dante Santiago, they called their trio Atban Klann (ATBAN: A Tribe Beyond a Nation). Will 1X (aka will.i.am), apl.de.ap, Mookie Mook, DJ Motiv8 (aka Monroe Walker), and Dante Santiago formed Atban Klann. Their debut album, Grass Roots, was never released due to Ruthless Records founder Eazy-E's death.

After Eazy-E died in 1995, Atban Klann reformed and changed their name to Black Eyed Pods, and then Black Eyed Peas. Dante Santiago was replaced with Jaime Gomez (Taboo), and Kim Hill became a steady background singer. Unlike the "gangsta rap" sounds of Los Angeles-based hip hop acts at the time, the trio performed with a live band and adopted a conscious musical and appearance style. After being signed to Interscope Records and releasing their debut, Behind the Front (1998) the group (and their accompanying live band) earned critical acclaim. One of the singles from the album was "Joints & Jam", and was featured on the Bulworth Soundtrack. Singer Sierra Swan joined in 1998, appearing on the 1998 song "Fallin' Up", before she left in 2000. Their second album, Bridging the Gap (2000), produced the singles "Weekends" featuring Esthero and "Request + Line" featuring R&B singer Macy Gray. Hill left the band while producing the album, but was still featured on the album tracks for "Hot" and "Tell Your Mama Come" as well as in the video for "Weekends".

Their third album Elephunk began development on November 2, 2001, but was not released until 2003. It was the first album to feature the vocals of current member Fergie. Nicole Scherzinger was originally approached to join the Peas, but was forced to decline because she was a member of Eden's Crush and was under contract. Fergie joined the group in 2002, introduced to will.i.am by Dante Santiago. Elephunk is also the first album that indicated and demonstrated the new, polished pop sound designed to attract mass audiences. In a positive review of the Black Eyed Peas' new-found style, Rolling Stone noted that since 2002, when the group "hired a blond bombshell named Stacy 'Fergie' Ferguson and gave up their pursuit of backpack-rapper cred, they have made a kind of spiritual practice of recording Futuristic songs – a total aesthetic commitment that extends from their garish wardrobes to their United Colors of Benetton worldview."

From Elephunk came "Where Is the Love?", which became the Black Eyed Peas' first major hit, peaking at No.8 on the U.S. Hot 100, but topping the charts in several other countries, including seven weeks at No.1 in the United Kingdom, where it became the biggest-selling single of 2003. The single had similar results in Australia, staying at No.1 for six weeks. In an interview with TalkofFame.com, Taboo shared that Justin Timberlake's split with Britney Spears impacted the recording of "Where Is The Love?". The album subsequently spawned "Shut Up", which peaked at No.2 in the UK and topped the charts in many success and went Gold and Platinum in the U.S., UK, Germany, and other European markets. The third single from the album, although significantly restyled from the original Elephunk version, "Hey Mama" hit the top 5 in Australia and the top 10 in the UK, Germany and other European countries and reached No.23 in the U.S. The song received even more exposure in 2003 when it was featured in the first "silhouette" television commercial for the iPod. Their fourth single from the album was titled "Let's Get It Started". Let's Get It Started" won a 2005 Grammy for Best Rap Performance by a Duo or Group and also received two nominations for Record of the Year and Best Rap Song. In 2004, the Black Eyed Peas embarked on the Elephunk Tour, hitting many countries in Europe, Africa, and Asia.
