In 1868, the German trading house of Carl Woermann established the first German settlement in Kamerun. This settlement was quickly followed by others, as German merchants raced to establish a presence in the territory before competing British and French agents.  On 14 July 1884, German explorer Dr. Gustav Nachtigal officially raised the German flag over Kamerun and declared it to be under German protection.

On 1 February 1887, a post office was opened at Kamerun, which was then the primary settlement in the territory.  The name of the town would be changed to Duala effective 1 June 1901.  This post office remained open until the early days of World War I, closing on 27 September 1914.
