Lieutenant General Lothar von Trotha Commander-in-Chief of the Imperial Protection Force for German South-West Africa from 1904 to 1905 in the fight against the OvaHerero, Nama, and Orrlam is rightly considered to be the main party responsible for the first genocide of the twentieth century in colonial Namibia. This critical edition gives the public access to central sources and Lothar von Trotha's diary and photo album for the first time.
