Quick Summary

The Porvoo Diet, held in 1809 in the city of Porvoo, was a pivotal event in Finnish history. Following Finland's cession from Sweden to Russia, the Finnish Diet swore allegiance to Tsar Alexander I. In return, Alexander I granted Finland autonomy as a grand duchy under Russian rule. This established Finland as a distinct political entity for the first time.123

From 1809 to 1863, Finland was governed by a bureaucracy appointed by the Russian emperor, with the Senate serving as the highest administrative body. This period is known as the era of bureaucracy. The Tsar, as the grand duke, was not required to convene the Diet regularly, and it did not meet again until 1863.12
