German Colonial aspirations in Asia and the Pacific ended with the start of the First World War. Japanese Army forces seized German leased territories in China and the Japanese naval forces occupied the German Pacific colonies. The Treaty of Versailles legitimized Japan���s aggression and the territories were officially mandated to the Japanese government. This collection comprises correspondence, studies and reports, cables, maps, and other kinds of documents related to U.S. consular activities.
