Drummer Mikko Sipola joined in late 1999, soon followed by the arrival of new vocalist Ville Viljanen in early 2000 when Haukio decided to focus on his guitar work.

[1] One year and two demos later, Mors Principium Est signed a three-album contract with Listenable Records completed by the album Liberation = Termination released in March 2007.

In March 2011, the band stated that members Tomy Laisto and Kalle Aaltonen had parted ways to pursue other ventures.

The band stated "If we still want to continue with Mors Principium Est, we need new guitar players" and proceeded to ask for anyone who could try out around the world to do so.
