History of Congo Red

Congo red was first synthesized in 1883 and successfully marketed as a textile dye by AGFA of Germany. The name “Congo” is a historical artefact as it was named around the time of the West Africa conference (commonly called the “Congo Conference”) when European powers debated the colonisation of Africa.

Many other dyes were also marketed using the “Congo” name in the following years, including Congo Brown and Congo Blue.
