The Gladiators are a Jamaican roots reggae band, most popular during the 1970s. The core was Albert Griffiths (guitarist and singer), Clinton Fearon (bassist and singer) and Gallimore Sutherland rhythm guitar and singer. The two most famous albums are Trenchtown Mix Up (1976) and Proverbial Reggae (1978) with songs as "Hearsay", "Jah Works", "Dreadlocks the Times is Now". "Mix Up", "Music Makers from Jamaica", and "Soul Rebel" – a song written by The Wailers. Gladiators also cooperated with the toaster U-Roy.

Albert Griffiths, singer and guitar player, was the founder of the reggae group The Gladiators. After some success with the singles "You Are The Girl" (a b-side to The Ethiopians hit record "Train to Skaville") in 1966, he recruited his childhood friends David Webber and Errol Grandison in 1968 to form the original Gladiators vocal group. The group's name was allegedly suggested by a fellow bus passenger during the time of their first recordings.

The group's first major success was with the single "Hello Carol" in 1968, for producer Coxsone Dodd, which topped the Jamaican music charts. Shortly afterwards, in 1969, Webber was stricken with illness and was replaced by Clinton Fearon, one of Griffiths' proteges. Similarly Grandison left the group in 1973 for family commitments and was replaced by Dallimore Sutherland.

During the early 1970s the Gladiators cut numerous records for various producers such as, Lloyd Daley and Lee Perry, but it was their recordings for Dodd at Studio One that became the biggest hits. During this time at Studio One the Gladiators hits included "Bongo Red", "Jah Jah Go Before Us", "Mr. Baldwin", and "Roots Natty".

The success of these recordings garnered the attention of Britain-based Virgin Records who gave the group their first major recording contract in 1976. Their debut full-length released on Virgin was the Tony Robinson produced Trenchtown Mix Up (1976), which included revisions of many of their early hits. They followed this effort with Proverbial Reggae (1978). At the time Gladiators was a band with Albert Griffiths on lead guitar and vocals, Clinton Fearon on bass guitar and vocals, Gallimore Sutherland on rhythm guitar and vocals, Sly Dunbar on drums, Lloyd Parks on bass, Uziah "Sticky" Thompson on percussion, Ansel Collins on keyboards and Earl 'Wire' Lindo on synthesizer. Errol Thompson and Joe Gibbs were their engineer and mixer, and Robinson the record producer.

Dodd and Studio One also released Studio One Presenting the Gladiators, (1978) a compilation of some early Gladiators records released 1968 - 1974. The Gladiators next two albums on Virgins were Naturality (1978) and Sweet So Till (1979). The group's next album Gladiators was recorded at Coach House Studios in the UK with local producer Eddy Grant. It was the first Gladiators album on which no member of the group played any of the instruments, as a few members of the band Aswad were brought in. The album did worse than their previous work, and they were subsequently dropped from their contract with Virgin. Virgin would subsequently release two compilation albums Vital Selection in 1981 and Dreadlocks The Time Is Now in 1983.

At the time, roots reggae was declining. A new type of reggae – based on drum machine, sampler, synthesizers and organ – occurred in the 1980s; ragga. One of the reasons for ragga's swift propagation is that it is generally easier, and less expensive to produce, than reggae performed on traditional musical instruments. Nevertheless the Gladiators released eleven studio albums in the 1980s. They soon found a home at U.S.-based Nighthawk Records and released Symbol of Reality in late 1982 followed by Serious Thing in 1984. One year later the Gladiators would change labels again, this time moving to Heartbeat Records, where they would release albums throughout the latter half of the decade. In 1987 Fearon left the group after eighteen years, but Griffiths and Sutherland have continued to release albums on various labels since then.

With the advent of dancehall in the 1990s, the Gladiators only released three studio albums during that decade. Eventually, the Gladiators, Mighty Diamonds, Bunny Wailer, Heptones and Burning Spear got a renaissance. The dancehall artists had to change their profile and baptized their new showmanship as conscious dancehall.

In 2005, the Gladiators released Fathers and Sons which has been regarded as Albert Griffiths farewell, with his sons, Alan and Anthony, joining the group.
