Commissariat in the context of "Reichskommissariat Ukraine"

Reichskommissariat (English: Realm Commissariat) is a German word for a type of administrative entity headed by a government official known as a Reichskommissar (English: Realm Commissioner). Although many offices existed, primarily throughout the Imperial German and Nazi periods in a number of fields (ranging from public infrastructure and spatial planning to ethnic cleansing), it is most commonly used to refer to the quasi-colonial administrative territorial entity established by Nazi Germany in several occupied countries during World War II. While officially located outside the German Reich in a legal sense, these entities were directly controlled by their supreme civil authorities (the Reichskommissars), who ruled their territories as German governors on behalf of and as representatives of Adolf Hitler.

The introduction of these territorial administrations served a number of purposes. Those established or planned to be established in Western and Northern Europe were in general envisioned as the transitional phases for the incorporation of Germanic countries outside pre-war Germany into an expanded Nazi state. Their eastern counterparts served primarily colonialist and imperialist purposes, as sources of Lebensraum for German settlement and the exploitation of natural resources.

The War Office has referred to several British government organisations throughout history, all relating to the army. It was a department of the British Government responsible for the administration of the British Army between 1857 and 1964, at which point its functions were transferred to the new Ministry of Defence (MoD). It was equivalent to the Admiralty at that time, which was responsible for the Royal Navy (RN), and (much later) the Air Ministry, which oversaw the Royal Air Force (RAF). The name 'Old War Office' is also given to the former home of the department, located at the junction of Horse Guards Avenue and Whitehall in central London. The landmark building was sold on 1 March 2016 by HM Government for more than £350 million, on a 250-year lease for conversion into a luxury hotel and residential apartments.

Prior to 1855, 'War Office' signified the office of the Secretary at War. In the 17th and 18th centuries, a number of independent offices and individuals were responsible for various aspects of Army administration. The most important were the Commander-in-Chief of the Forces, the Secretary at War, and the twin Secretaries of State; most of whose military responsibilities were passed to a new Secretary of State for War in 1794. Others who performed specialist functions were the controller of army accounts, the Army Medical Board, the Commissariat Department, the Board of General Officers, the Judge Advocate General of the Armed Forces, the Commissary General of Muster, the Paymaster General of the forces, and (particularly with regard to the Militia) the Home Office.
