The law of war at sea is a regulation of military disputes that was supplemented primarily in the Hague Agreement of 1907, but also (for the wounded, sick, prisoners of war) in the Geneva Convention of 1949 as well as by customary international law . Since the naval war is only a small part of the destruction of the enemy naval forces and is increasingly a trade and economic war (war of blockades), the law of neutrality plays a greater role, i.e. the possibility of preventing supplies to the enemy if the deliveries come from a neutral country or are made on neutral ships. The principles of the right of seizure and removal were laid down in the Paris Declaration of the Law of the Sea of 1856, later completed by the - not ratified - London Declaration of the Law of the Sea of 1909, but were largely abandoned again in the two world wars.
