Hypnos was formed in the Czech town of Staré Město in 1999 by singer and bassist Bronislav "Bruno" Kovařík and drummer Peter "Pegas" Hlaváč, who were both previously in the death metal band Krabathor.

The band's second album, The Revenge Ride, which again included Tomáš Kmeť on keyboards as well as new guitarist David Menšík, came out in 2001 and was produced by Harris Johns (Helloween, Kreator, Voivod, Sodom).

This latest record featured newly inducted guitarist Milan "Butch Mills" Večerka, with Menšík playing on several songs, among other guests.

The album, which included an English cover of the Törr song "Kult ohně" (under the title "Tribe Fire Ritual"),[3] was nominated for an Anděl Award in the Hard and Heavy category.

By late 2011, the band signed with German label Einheit Produktionen and a year later, released the album Heretic Commando / Rise of the New Antikrist, having added Vlastimil "Vlasa" Urbanec on second guitar.
