The band was formed in 1988 in Cali, Colombia by Dagon. The band started as a thrash metal act, and in 1994 evolved into raw black metal.
In 1996, Dagon left Colombia and moved back to the United States to continue Inquisition and search for a new drummer. That same year Dagon met Incubus, who joined the band on drums and the creation of their debut full-length album began. This line-up has remained stable for more than fifteen years and is now seen as the classic Inquisition line-up.
Inquisition's style of black metal involves slow, deep and dark riffing combined with sudden tempo changes to faster sections based around blast beats and high-speed riffing; at times adding melodic solos. The classic Inquisition sound involves the combination of old school thrash metal-influenced riffs with darker and more chaotic black metal, primarily involving fast, tremolo picked minor-key guitar riffs, thus creating the trademark "Inquisition sound".
Dagon is originally from the United States, but had moved to Colombia. Inquisition's early records were first released in Colombia and it was there that they first performed live playing alongside bands such as Reencarnación, among others.
According to an interview with Heavy Metal Home TV, Inquisition had a bass player in 1998 but he was kicked out due to drug-related problems.
Appeared in 1999 on the Compilation "From Colombia with Hate" CD by Sylphorium Records with the song "The Initiation".
