Multilateral treaties of the German Reich 1871 to 1945 as well as individual older treaties, as far as they kept their validity after the foundation of the Reich 1871. Besides the actual components of the treaties, such as treaty documents, powers of attorney, exchange protocols, announcements and ratification documents, in some cases there is also supplementary archive material, such as conference protocols or maps. In principle, this includes everything that required international regulation: For example, shipping, even on the major rivers, industrial standards such as the Metre Convention or the Radiotelegraph Treaty, treaties in the wake of the First World War (Brest-Litowsk, Versailles, Locarno), but also the final documents of important international conferences such as the Berlin Treaty of 1878.
