芬蘭大公
The February and October Revolutions in 1917 ignited hope in the Grand Duchy of Finland. After the abdication of Tsar Nicholas II on 2 March (15 March N.S.) 1917, the personal union between Russia and Finland lost its legal base – at least according to the view in Helsinki – as he was the Grand Duke of Finland. Negotiations began between the Russian Provisional Government and Finnish authorities.
