The Senate was headed by the Governor-General of Finland. The Senate was divided into the economic division and the judicial division. In 1822 both divisions were given a Finnish vice-chairman. From 1858 and onwards the members of the senate were formally known as senators. Due to the Civil War in 1918 the Senate was relocated to the town of Vaasa from January 29 to May 3.
In 1918 the economic division became the Cabinet and the judicial division became the Supreme court of the independent Republic of Finland. The vice-chairman of the economic departement became the Prime minister of Finland, and the other senators became ministers.
A senate is a deliberative body, often the upper house or chamber of a legislature.
In the United States, each of its member states has a Senate and a lower chamber, known variously as the House of Representatives, House of Delegates, General Assembly or Assembly, except for the state of Nebraska, where the Senate is the only body of a unicameral legislature.
Until 1919, the Senate of Finland was the executive branch and supreme court.
