The Oberkommando der Marine (OKM) was the high command of the German Navy during World War II. Established in 1935, it was responsible for naval strategy, operations, and administration. The OKM played a crucial role in coordinating naval forces and planning maritime operations against the Allies. The organization was led by notable figures such as Erich Raeder and later Karl Dönitz. The OKM oversaw various naval units, including submarines and surface fleets, and was instrumental in implementing Germany's naval warfare strategies throughout the conflict.
