 Before 1910, there was no codification of the relationship between Finland and Russia in Russian law, so the Finnish Senate and the Finnish Diet in particular were, for a long period of time, spanning from the revival of the Diet of the Estates in 1863 to the threshold of russification in the 1880s, allowed to act as if Finland was a state separate from that of Russia.As a result, the eventual subjugation of the Finnish diet to Russian governmental organs in between 1899 and 1905 and again from 1908 was viewed as unconstitutional in Finland, as was the 1910 codification of Finland's position as an indivisible part of the Russian Empire governed according to a "set of special laws".After the February Revolution in March 1917, the Russian Provisional Government repealed all of the restrictions imposed on Finnish autonomy from February 1899.
