Why were German submarines prohibited by the Treaty of Versailles?

The Treaty of Versailles prohibited Germany from possessing submarines as part of a broader effort by the Allied powers to ensure that Germany would not revive as a military power following World War I.12

During the war, German U-boats had caused significant destruction to Allied and neutral shipping, nearly cutting off Britain's Atlantic lifeline. To prevent a resurgence of this threat and to dismantle Germany's capacity for future aggression, the treaty imposed strict disarmament measures. These included limiting the German navy to a small number of surface ships and personnel, while explicitly banning the construction or possession of submarines. These restrictions were intended to be the first step in a worldwide process of disarmament, though they were deeply resented in Germany and eventually repudiated by Adolf Hitler in 1935.312
