The Wehrmacht (, lit. "defence force") was the unified armed forces of Nazi Germany from 1935 to 1946. It consisted of the Heer (army), the Kriegsmarine (navy) and the Luftwaffe (air force). The designation Wehrmacht for Nazi Germany's military replaced the previously used term, Reichswehr (1919–35), and constituted the Third Reich’s efforts to rearm the nation to a greater extent than the Treaty of Versailles permitted.
