release on their newly founded label Spiderleg Records. The group's debut EP, Demolition War, subsequently appeared on Spiderleg in December 1981. Subhumans released two more EPs in 1982, Reasons for Existence and Religious Wars, as well as founding their own record label, Bluurg Records. Although initially focused on releasing cassette recordings, the label produced its first vinyl release with the "Wessex '82" EP, which featured one track each by the Subhumans ("No Thanks"), The Pagans, Organised Chaos and The A-Heads.

The band's first LP, The Day The Country Died was released in 1983 on Spiderleg Records. Generally considered a classic of the anarcho-punk era, it was followed shortly after by the Evolution EP, which was also the band's first record (bar the "Wessex '82" split) to be released on their own label. The band released Time Flies... But Aeroplanes Crash later that same year, a 12" EP consisting of both studio and live tracks - the live tracks taken from an aborted live album. Towards the end of the year, original bassist Grant left the band (shortly before the recording sessions for their second album) and was replaced by Phil of the Pagans. (Bruce Treasure, Andy Gale, Grant Jackson, Trotsky and Phil Bryant all attended Kingdown Comprehensive school in Warminster, England).

The following year, the band released their second album, From the Cradle to the Grave. The release demonstrated a notable musical development for the band, particularly with the title track - a progressive piece that took up the album's entire second side, and ran for almost 17 minutes. It was followed by one last EP, Rats, in January 1985, and the EP-LP release - a compilation album comprising the band's first four EPs.

Subhumans broke up at the end of 1985, after recording their third album Worlds Apart, with musical differences being cited as the main reason for the split. A final 12" record (1986's 29:29 Split Vision) was also recorded and released posthumously, and demonstrated just how far the band's musical leanings had altered from their initial hardcore punk stylings. Lucas subsequently joined Culture Shock in 1986 and then formed the political ska punk band Citizen Fish in 1990. A second Subhumans compilation album was released the same year (Time Flies + Rats), which comprised the two later EPs absent from the EP-LP release.

Subhumans had a brief reunion for a couple of shows in about 1991, and a more comprehensive return in 1998, which included UK and US concerts. This resulted in a semi-permanent return of the band as a touring entity, including at least two major tours of North America in the twenty-first century – the Live in a Dive recording released on Fat Wreck Chords being a product of the second tour recorded at the Showcase Theatre in Corona, CA. The band also recorded and released a new EP, Unfinished Business, in 1998, which consists of previously unreleased songs from the band's original incarnation.

Since then, Subhumans have recorded a new album, Internal Riot, and self-released it on Bluurg Records in September 2007. They toured in Europe throughout 2007, and a month-long U.S. tour began on 24 August that year. They have maintained a live presence ever since. For nearly a decade, Subhumans continued to make multiple live performances across the UK and the US, and on 13 September 2019, Subhumans released a new album titled Crisis Point, which was the band's first album in 12 years. The album covered several modern-day issues while moving back into the anarcho-punk genre, with its messages and general punk tune in the song.
