Originally formed under the name Devastator. The current band name is short for 'The Obliteration of Humanity'.

Schizoid did the vocals on the demo cassettes.

!T.O.O.H.! disbanded shortly after putting the finishing touches on the Ràd a Trest (Order & Punishment) album due to financial issues (caused in no small part by Elitist Records (an imprint of Earache) being abandoned by Earache, who took the album out of print only two months after its release).

The band recorded a 3 track-demo, titled Z terária do Kolumbária in 2004, but it was never released.
