Karl Dönitz was a German admiral during World War II, best known for his command of the German U-boat fleet and later as the last President of Nazi Germany. He played a pivotal role in the Battle of the Atlantic, where his submarines sought to disrupt Allied shipping. Dönitz succeeded Adolf Hitler as head of state after Hitler’s death in April 1945. He authorized Germany’s unconditional surrender to the Allies in May 1945. At the Nuremberg Trials, Dönitz was convicted of war crimes, particularly for his U-boat warfare tactics, and sentenced to ten years in prison.
