Finland
- The status of the Grand Principality of Finland, ruled from 1809 to 1917 by the czar of Russia as the Grand Prince of Finland, resembled a personal union in some aspects and is sometimes described as such by Finns. In accordance with the Treaty of Fredrikshamn, Finland was legally a part of the Russian Empire that was granted autonomy at the sufferance of the czar; the autonomous status was temporarily repealed later. By the 1860s, with the revival of the diet of the estates, Finns grew to consider Finland a constitutional monarchy in real union with Russia. For a time Finland was in fact allowed to act as though it was a separate state. As a result the codification of Finnish autonomy and subordinance to Russian governmental organs from 1899 onwards was not recognized by the Finns and was condemned as unconstitutional.
