2008 Inquisition was formed in 1988 in
Cali, Colombia, by Dagon as a
thrash metal act named Guillotine. The band changed their name to Inquisition in 1989. The name, frontman Dagon later explained, was chosen because it represented humanity's "need to establish dominance, control and order based on a particular period of our world's history." Debandt departed the band shortly after the release of Inquisition's full-length debut,
Into the Infernal Regions of the Ancient Cult, in 1998. As revealed to be in the public record by metal news website
MetalSucks, Dagon pleaded guilty to Unlawful Display of Sexually Explicit Material and Obstructing a Law Enforcement Officer in a plea bargain after the
National Center for Missing & Exploited Children detected an account uploading sexually explicit photographs of "young females in their early teens or pre-teens" to the photo-sharing website
Photobucket in November 2006, the account being traced to Dagon. A subsequent investigation of his computer revealed as many as 2,000 files recovered depicting Inquisition, Dagon and his wife, and more child pornography, involving both young girls and boys. Enough of the latter category existed to fill four DVDs with images and videos. The charges did not require him to register on the Washington Sex Offender Public Registry.
Recent efforts In the aftermath of the resurfaced allegations against Dagon, the band went silent on their social media for the majority of 2018, however in late December of that year the band announced on their Facebook that they had started working on new music. A year later in late December 2019, they announced they had completed recording their next album. On November 11, 2020, the band released a music video for their song "Luciferian Rays" to promote their next album. The band's eighth full-length album
Black Mass for a Mass Grave was released on November 20, 2020, through Agonia Records.{{Cite web|url=http://label.agoniarecords.com/index.php?a=0NhEiQBw88lAHpRQgBf4v%2B6K3alK%2B%2FkGXYXvg9spPM1lEcX87SUnSw%3D%3D == Musical style ==
