Freedom of the seas is a principle in the international law and law of the sea. It stresses freedom to navigate the oceans. It also disapproves of war fought in water. The freedom is to be breached only in a necessary international agreement.
Absolute freedom of navigation upon the seas, outside territorial waters, alike in peace and in war, except as the seas may be closed in whole or in part by international action for the enforcement of international covenants.
The United States' allies Britain and France were opposed to this point, as France was also a considerable naval power at the time. As with Wilson's other points, freedom of the seas was rejected by the German government.
