　　 In 1904, several dead bodies of the Herero tribe lay on the ground in Namibia, southwest Africa. Herero rebels attacked the Otavi railroad under construction through their region. This was followed by a massacre of Herero railroad construction workers by the German Reich forces.

　 The German Reich's Kaiser Wilhelm II became the distributing power of the colony in the Partition of Africa Agreement of the Berlin Conference of November 15, 1884. A few years earlier, a German tobacco merchant named Adolf Rüderditz arrived in the Nigerian town of Lagos in 1881. He later plundered part of that territory in the town of Angra-Pekena on the Namibian coast. Von Bismarck declared Namibia a German protectorate on August 7, 1884.

　In Namibia in southwestern Africa, Herero chief Samuel Maharero rose in rebellion in 1896. He was followed by the Herero rebellion on January 11, 1904, when he attacked German troops and settlers. As a result, 123 German settlers were killed. The extremely cruel General Lothar von Tolosa was appointed to the German army. The Herero tribe, found on the German-occupied border, declared that they would shoot children and women, with or without rifles and with or without livestock. The endangered Nama people of the south also joined the rebellion. About 14,000 German troops crushed the Herero and Nama rebellion with a massacre. The Herero and Nama were shot, hung from trees, and quantitatively slaughtered in the desert due to hunger and thirst. A concentration camp set up on Shark Island in Lüderitz Bay held about 12,000 of the rebels. About 80% of the Herero population of Namibia was wiped out. After the Herero rebellion, some 60,000 Herero and 10,000 Nama were exterminated and expelled from Namibian lands. After losing World War I, Germany signed the Treaty of Versailles in 1919 and lost all its colonies.

　 The Namibian genocide was the first genocide of the 20th century, when the Imperial German Army brutally oppressed Namibia's indigenous Herero and Nama people between 1904 and 1908.In 2004, the German government officially apologized for the Namibian genocide, and in 2019 the German Parliament called it genocide and described it as genocide.In May 2021, an agreement was signed to repair the damage done to Namibian victims.
