Ministry of the interior


An interior ministry (sometimes ministry of internal affairs or ministry of home affairs) is a government ministry typically responsible for policing, emergency management, national security, registration, supervision of local governments, conduct of elections, public administration and immigration matters. The ministry is often headed by a minister of the interior or a minister of home affairs. In some countries, matters relating to the maintenance of law and order and the administration of justice are the responsibility of a separate justice ministry.

In some countries, policing and national security belong to a separate ministry (often titled "ministry of public order", "ministry of security" etc.), with the interior ministry being limited to control over local governments, public administration, elections etc. Notable examples include Greece (ministry of citizen protection) and Israel (ministry of public security).

In countries with a federal constitution, an interior minister will often be found at both the federal and sub-national levels. Similarly, autonomous entities and dependent territories may also have interior ministers.

In certain jurisdictions, similarly named government departments may have other responsibilities. In the United States, the Department of the Interior has radically different functions—primarily the management and conservation of natural resources, and programs and policies dealing with indigenous peoples of the U.S. The functions that fall under what most other countries call an "interior ministry" are under other government departments—mostly the Department of Homeland Security (with functions such as public safety and disaster relief), with some others falling under the Department of Justice (with functions such as handling the national police and the management of prisons).
