In 1868, the German trading house of Carl Woermann established the first German settlement in Kamerun (modern-day Cameroon and surrounding area). 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. Nachtigal officially raised the German flag over Duala and declared Kamerun to be under German protection. The German presence in Kamerun would grown in the period between 1884 and the outbreak of World War I, and post offices would be established in over 50 locations.
As with most of the German Colonies, the Kamerun postage consisted of overprints of German issues, followed by versions of the Yacht Issues.
The collection also features several provisional issues used during periods of postage shortages in Kamerun.
At the outbreak of World War I, English forces quickly captured the coastal areas, and began pushing the small German and Native constabulary force into the interior of the territory. By February 1916, the German forces were low on supplies, so they retreated into neighboring Spanish Rio Muni, where they were interned. The last German station in the territory, Mora, fell on 16 February 1916.
