Prime Minister's Office (Finland)
The Senate of Finland was founded on 18 August 1809 in the Grand Duchy of Finland when Emperor Alexander I of Russia signed a standing order on its establishment at Peterhof Palace. The Senate was initially called the Governing Council until it was renamed as the Senate in 1816. The Senate of Finland was divided into the Economic and Judicial Divisions; the Economic Division was further divided into departments, such as the Office Administrative Department (; ). On 1 October 1892, the Office Administrative Department was disbanded and the modern equivalent position of Prime Minister in the Senate, the Vice-Chairman of the Economic Division, was granted a support office in its place. The new unit was called the Office of the Economic Division (; ). Following Finnish independence in 1917, the unit was renamed as the Prime Minister's Office on 27 November 1918 with the operations and staff remaining intact.
Greater Finland
The Karelo-Finnish Soviet Socialist Republic (KFSSR) was founded by the Soviet Union at the beginning of the Winter War, and was led by the Terijoki government and Otto Wille Kuusinen. This new entity was created with an eye to absorbing a defeated Finland into one greater Finnic (and Soviet) state, and so the official language returned to Finnish. However, the Soviet military was unable to completely defeat Finland, and this idea came to nothing. Despite this, the KFSSR was maintained as a full union republic (on a par with Ukraine or Kazakhstan, for example) until the end of the Stalinist period, and Finnish was at least nominally an official language until 1956. The territory Finland was forced to cede under the Moscow Peace Treaty was incorporated partly into the KFSSR, but also into Leningrad Oblast to the south and Murmansk Oblast to the north.
