The Wehrmacht was the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the Heer (army), the Kriegsmarine (navy) and the Luftwaffe (air force). The designation "Wehrmacht" replaced the previously used term Reichswehr, and was the manifestation of the Nazi regime's efforts to rearm Germany to a greater extent than the Treaty of Versailles permitted.

After the Nazi rise to power in 1933, one of Adolf Hitler's most overt and audacious moves was to establish the Wehrmacht, a modern offensively-capable armed force, fulfilling the Nazi regime's long-term goals of regaining lost territory as well as gaining new territory and dominating its neighbors. This required the reinstatement of conscription, and massive investment and defense spending on the arms industry.
