AFRICANGLOBE - German troops committed the first genocide of the 20th century in Namibia which was then known as German South-West Africa. In 1904, the German general Lothar vonThrotha used an uprising against the colonialists as pretext to slaughter around 70,000 Hereros, which amounted to about 80 percent of its population. The troops also wiped out half of the people of the Nama ethnic group. The UN officially called the killings a genocide as early as 1948. But Germany refuses to do so to this day.
