German colonial territories were regions outside Europe that were controlled by the German Empire from the late 19th century until the end of World War I. These territories included parts of Africa, the Pacific, and China, and their acquisition was driven by Germany's desire for resources, land, and status as a global power. The loss of these colonies after World War I created unresolved tensions and feelings of resentment in Germany, contributing to the rise of nationalist sentiments in the interwar period.
