Kellogg–Briand Pact
Before and during the events of World War I, the German state was called an "empire" in English and Wilhelm II was titled "His Imperial and Royal Majesty the German Emperor." After the War and the abolition of the monarchy during the German Revolution of 1918–19, however, when Wilhelm was forced to abdicate, the official English name for Germany was the "German Reich": "Reich" was left untranslated and no longer referred to an "empire" but, instead, took on the connotation of "Realm" or "State". "German Reich" was used in legal documents and English-language international treaties—for example, the Kellogg–Briand Pact and the Geneva Conventions.
