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.
Provinces of Finland
Between 1634 and 2009, Finland was administered as several provinces (, ). Finland had always been a unitary state: the provincial authorities were part of the central government's executive branch and the provinces had little autonomy. There were never any elected provincial parliaments in continental Finland. The system was initially created in 1634. Its makeup was changed drastically in 1997, when the number of the provinces was reduced from twelve to six. This effectively made them purely administrative units, as linguistic and cultural boundaries no longer followed the borders of the provinces. The provinces were eventually abolished at the end of 2009. Consequently, different ministries may subdivide their areal organization differently. Besides the former provinces, the municipalities of Finland form the fundamental subdivisions of the country. In current use are the regions of Finland, a smaller subdivision where some pre-1997 "lääni"s are split into multiple regions. Åland islands retain their special autonomous status and their own regional parliament.
