The States of the Weimar Republic were the first-level administrative divisions and constituent states of Germany during the Weimar Republic era. The states were established in 1918 following the German Revolution upon the conclusion of World War I, and based on the 21 constituent states of the German Empire that abolished their local monarchies. The new states continued as republics alongside the three pre-existing city-states within the new Weimar Republic, adopting the titles Freistaat ("Free State") or Volksstaat ("People's State").
