In the year of 1992 the band released the "End of Life" demo. The demo contains only one song which is around 11 minutes. The line up at the time of recording the demo was: Storm - on bass and vocals, Lars Fredrik Bergstrøm - on guitars and Jardar - on drums. The guitars were written by Lars Fredrik Bergstrøm (1974 - 2014). In 1993 the band changed the name to "Strid" which means "Battle" in Norwegian. That same year, Strid re-released their "End of Life" demo under their new name, through the German label "Malicious Records". After releasing the "End of life" demo, Lars Fredrik Bergstrøm left the band and was replaced by Ravn Harjar. Through the years between 1993 and 1995, the band writes and records the self-titled EP which was released through Malicious Records and contains only two songs - "Det hviskes blant sorte vinder" which means "It Is Whispered Amid the Black Winds" in Norwegian and "Nattevandring" which means "Nightwandering" in Norwegian. The music style and sound of this demo is more ambient/atmospheric black metal oriented. Mainly because of this release, the band is commonly recognised as the creators of depressive black metal along with some other bands from the second wave of black metal music. At this time the band line up contains: Ravn Harjar - on guitars, Storm - on bass and vocals and Jardar - on drums. After the releasing of the self-titled EP, there was no any official releases by the band.

In the year of 2007, the Greek label Kyrck Productions & Armour re-released all the previous material released by the band from the past which contains all "Malfeitor/Battle/Strid" material. Somewhere between 2009 and 2010 there was a reunion of the band with old members including Vicotnik (Dødheimsgard, ex-Aphrodisiac, ex-Ved Buens Ende, ex-Manes, ex-Code, ex-Naer Mataron, ex-Endwarfment). Another member that was part of the reunion was Lars Fredrik Bergstrøm - the main composer of the "End of Life" track. In 2014 Lars Fredrik Bergstrøm died. At this time the band line up contains Ravn Harjar - on guitars and vocals, Vicotnik - on bass and Sigmund (ex-Inflabitan, ex-Dødheimsgard) - on guitars. In January 2015, Ravn Harjar wrote a statement on the official Strid Facebook page that in the autumn of the year 2015 the band will start recording their first full-length album which will be titled "Endetid".

R. R. Tolkien's legendarium. The parties to the dispute were band founder Infernus (Roger Tiegs) and members Gaahl (Kristian Espedal) and King ov Hell (Tom Cato Visnes). It began in October 2007, when it was announced that Gaahl and King had decided to part ways with Infernus, although the former two claimed to have "fired" the latter. The dispute was concluded in March 2009 when a court verdict recognising Infernus as the legitimate user of the name was announced, and the outcome of the dispute also established a precedent in Norway for subsequent similar disputes.
