As the capital of Italy, Rome hosts all the principal institutions of the nation, including the Presidency of the Republic, the government (and its single ''Ministeri''), the Parliament, the main judicial Courts, and the diplomatic representatives of all the countries for the states of Italy and Vatican City. Many international institutions are located in Rome, notably cultural and scientific ones, such as the American Institute, the British School, the French Academy, the Scandinavian Institutes, and the German Archaeological Institute. There are also specialised agencies of the United Nations, such as the FAO. Rome also hosts major international and worldwide political and cultural organisations, such as the International Fund for Agricultural Development (IFAD), World Food Programme (WFP), the NATO Defense College and the International Centre for the Study of the Preservation and Restoration of Cultural Property (ICCROM).
