Wegner explained on his trip that he wanted to strengthen and deepen the city partnership with Windhoek. "Both cities are linked by a wide range of cooperation in the areas of culture, education, business, research, sport and the promotion of democracy - but also by our historical responsibility in commemorating the German colonial era." In the colony of German South West Africa, now known as Namibia, soldiers of the German Empire brutally crushed resistance by the Herero and Nama from 1904 to 1905. Tens of thousands of people were killed. Historians see this as genocide.
