A protecting power is a country that represents another sovereign state- the protected power- in a third country where the protected power lacks its own formal diplomatic representation (e.g., lacks an embassy or consulate).[2] It is common for protecting powers to be appointed when two countries break off diplomatic relations with each other. The protecting power is responsible for looking after the protected power's diplomatic property and citizens in the hosting state. If diplomatic relations were broken by the outbreak of war, the protecting power will also inquire into the welfare of prisoners of war and look after the interests of civilians in enemy-occupied territory.
The institution of protecting power dates back to the Franco-Prussian War of 1870 and was formalized in the Geneva Convention of 1929. Protecting powers are authorized in all four of the Geneva Conventions of 1949. In addition to sovereign states being appointed as protecting powers, the International Committee of the Red Cross may be appointed a protecting power under Protocol I (1977). The practice of selecting a protecting power in time of peace was formalized in the Vienna Convention on Diplomatic Relations (1961).[3][4]
