Afro-Germans () or Black Germans () are people of Sub-Saharan African descent who are citizens or residents of Germany. Cities such as Hamburg and Frankfurt, which were formerly centres of occupation forces following World War II and more recent immigration, have substantial Afro-German communities. With modern trade and migration, communities such as Frankfurt, Berlin, Munich, and Cologne have an increasing number of Afro-Germans. , in a country with a population of 83,000,000 people, there were an estimated 1,000,000 Afro-Germans. History African and German interaction 1600 to late 1800s During the 1720s, Ghana-born Anton Wilhelm Amo was sponsored by a German duke to become the first African to attend a European university; after completing his studies, he taught and wrote in philosophy. Later, Africans were brought as slaves from the western coast of Africa where a number of German estates were established, primarily on the Gold Coast. After King Friedrich Wilhelm I of Prussia sold his Ghana Groß Friedrichsburg estates in Africa in 1717, from which up to 30,000 people had been sold to the Dutch East India Company, the new owners were bound by contract to "send 12 negro boys, six of them decorated with golden chains," to the king. The enslaved children were brought to Potsdam and Berlin. Africans and German interaction between 1884 and 1945 At the 1884 Berlin Congo conference, attended by all major powers of the day, European states divided Africa into areas of influence which they would control. Germany controlled colonies in the African Great Lakes region and West Africa, from which numerous Africans migrated to Germany for the first time. Germany appointed indigenous specialists for the colonial administration and economy, and many young Africans went to Germany to be educated. Some received higher education at German schools and universities, but the majority were trained at mission training and colonial training centers as officers or domestic mission teachers. Africans frequently served as interpreters for African languages at German-Africa research centers, and with the colonial administration. Others migrated to Germany as former members of the German protection troops, the Askari. The Afrikanisches Viertel in Berlin is also a legacy of the colonial period, with a number of streets and squares named after countries and locations tied to the German colonial empire. It is now home to a substantial portion of Berlin's residents of African heritage. Interracial couples in the colonies were subjected to strong pressure in
