The band was formed in the beginning of 1997 in Ketrzyn (Poland).
The first line-up: Slawek "SZYCHA" Szuszczewicz (guitars, vocals), Jurek Dacko (bass), Jarek "YARO" Paprota (drums), Tomek "ZAKAMAR" Kaczmarczyk (guitars). In such line-up the musicians began to work on their compositions. While working on the debut material DISLOYAL performs at several local events and festivals. Finally in December 1997 the band decides to enter SELANI studio in Olsztyn, where under the guidance of sound-engineers and producers such as Doc (VADER) and Simon (ex-PROPHECY) record their debut called "Desire". This move allowes DISLOYAL to expand their activity and gives the opportunity to present themselves to a wider audience. "Desire" has been very well-received in the underground scene and beyond it, as shown by the excellent reviews and a number of interviews in various metal music magazines, radio presentations, participation on a variety of compilations, like: "Blood to come vol.8" and "Adrenalina cz.5" (THRASH`EM ALL), etc. In one word, the aim, which the musicians put for such material has been achieved and the reaction of audience was unexpectedly good. After launched promotion and playing a few gigs Jurek leaves the band and Tomek "MACABRE" Korzeniewski takes his place. In 1998 DISLOYAL sign the deal with Creativ PRODUCTION from Lublin, which releases „Desire”. In the end of 1998 in the competition for the best band of the Warmia-Mazury region, DISLOYAL take a place alongside such bands as VADER and CHRIST AGONY, which shows the high level of the entire band. In December 1998 DISLOYAL visit SELANI studio again and record their debut LP, which is called "PESSIMISTIC" and also shoot the first video for the song "THE PAIN OF EXISTENCE", where Andy Bomba (SELANI sound producer) appears as a guest on vocals. The CD contains 8 tracks plus intro composed by Andy. The whole record is kept in climates of technical and melodic death metal, which gives a great effect and a new view of XXI century metal. The band signs with DEMONIC RECORDS and in June 1999 sets off on the first tour as a support for the well-known DEVILYN.

During this PAIN DOMINATION TOUR`99, which lasts for 2 weeks, DISLOYAL present themselves to the big audience in the bigest cities in Poland, where they were really positively and warmly received. The band together with DEMONIC RECORDS do its best to promote the debut album in Poland and abroad. In September 1999 DISLOYAL performs at the second edition of METAL MONSTERS FESTIVAL. In June 2000 album „AVENGER” appears in CD version, which contains two remastered previous releases: the demo "Desire" and the album "PESSIMISTIC" as well as few surprises. Also in June, the band records one song in studio "HENDRIX" in Lublin, with the intention to promote new material before its official release. The musicians, however, decided that the new composition is not going to fulfil this mission and will go to the band’s archives. In November 2000 the next line-up change takes place. Guitarists SZYCHA and ZAK are replaced by LUKAS (guitars.,vocals) and TOMASH (guitars), who have previously played in the death metal band PANZERFAUST. In September 2001 the cooperation with DEMONIC RECORDS is broken, due the suspension of its activities. In the end of December 2001 after playing a few gigs, DISLOYAL records a three songs promo "I AM THE PLAGUE" in the studio "HERTZ" in Bialystok, which aim was to show people in the music industry and the fans the current style of the band, as well as to remind about DISLOYAL after quite a long break. In May 2003 musicians enter "HERTZ" again and record the next album "THE KINGDOM OF PLAGUE". These are 10 tracks in the climate of brutal death metal and cover of IMMORTAL as a bonus. In the beginning of 2005 the band signs papers with REDRUM label from Warsaw to release this CD. LUKAS leaves the band and MACABRE takes his place changing the bass for the guitar and vocals. In June 2005 the new bass player RHENAUZ joins DISLOYAL, but after several gigs promoting the album, he also leaves the band. Since March 2007 DISLOYAL’s new session bassist is ARTYOM SERDYUK from the Belarusian technical death metal band DEATHBRINGER, session musician for such bands as: ID:VISION, MEDEA, AMENTIA. In June 2007 the recording session of the new material starts in the band’s home studio and lasts until September 2007. It results in 9 brutal death metal tracks united under the name „PROPHECY”. In the spring of 2008 DISLOYAL signs a single album release contract with a possible extension for another release with the German label NO COLOURS RECORDS, which is followed by the European premiere of "PROPHECY" in April 2008.

After this release MACABRE and TOMASH leave the band. The bassist ARTYOM enters the main line-up but as a guitarist, and starting from 2009 DISLOYAL take a brake in the concert activity and ARTYOM and JARO begin working under the creation of the new material. Thus begins a completely new phase in the band’s history. The musicians have a very thorough and careful approach to the creation of the album and finish working on it only in the beginning of 2012, also because ARTYOM has to devote time to other bands, in which he performs: DEATHBRINGER, THY DISEASE, AMENTIA, WOE UNTO ME. In the beginning of 2012 a new bass player also joins DISLOYAL – KOLYA KISLYI – another musician from Belarus. In August 2012 the band enters MONROE SOUND STUDIO in Stargard Szczecinski and records drums, bass and guitars for the new release, which promises to be very tough, loud, powerful and significant event in the history of DISLOYAL.
