Protecting power

A protecting power is a country that represents another country (the protected power) in a third country where the protected power has no official diplomatic mission. They are chosen when two countries break off diplomatic relations or when war makes direct diplomacy impossible. The protecting power guards the protected power’s diplomatic premises and its citizens in the host country. In war, they also look after prisoners of war and civilians in enemy-held areas.

Origins and rules: The idea began in the Franco-Prussian War (1870–71) and was formalized in the Geneva Convention of 1929. All four Geneva Conventions of 1949 mention protecting powers. The International Committee of the Red Cross can act as a protecting power under Protocol I (1977). In peacetime, the Vienna Convention on Diplomatic Relations (1961) requires the protected power to appoint a protecting power that the host country accepts, and that protecting power must maintain relations with both states. In wartime, the protecting power must be neutral.

What they do: A protecting power can perform many of the protected power’s diplomatic tasks when relations are so broken that there is little or no diplomatic staff in the other country. They protect the protected power’s interests, assist its citizens, and manage matters like prisoner lists, prisoner visits, and sometimes prisoner exchanges. They may run an “interests section” inside their own embassy for the other country’s people. For example, the Cuban Interests Section in Washington was run inside the Swiss Embassy.

Examples and notes: Sometimes more than one protecting power is chosen, and different sides may appoint different protectors if those choices are acceptable to the host country. In practice, protecting powers have included neutral states like Switzerland and Sweden, which have handled many mandates during major conflicts, and the system has adapted with international organizations stepping in when needed. The concept remains a key way to protect people and property when direct diplomacy is not possible.
