which then pushed for laws restricting Finnish autonomy. Russia demanded higher payments and the Senate of Finland was replaced with the admiral-senate or saber-senate. Nicholas II pushed for complete russification and the end of Finnish autonomy in 1914, but this was halted by the beginning of the First World War. The Jäger Movement was formed and sent first 200, and later 1900, Finnish volunteers to Germany to be trained as Jägers (elite light infantry) for armed resistance. The Finnish Jägers formed the 27th Jäger Battalion and were eventually sent to Libau to fight against the Russian Empire. Sibelius composed the Jäger March on lyrics written by Heikki Nurmio, who served in the 27th Battalion. Discussions in 1917 Revolution in Russia 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. Power act The resulting proposal, approved by the Russian Provisional Government, was heavily rewritten in the Finnish Parliament and transformed into the so-called Power Act (Finnish: Valtalaki, Swedish: Maktlagen), whereby the Parliament declared itself to now hold all powers of legislation, except with respect to foreign policy and military issues, and also declared that it could be dissolved only by itself. At the time of the vote it was believed that the Provisional Government would be quickly defeated by the rebellion in Saint Petersburg. The Provisional Government survived, however, and disapproved of the Power Act and dissolved the Finnish Parliament. After new elections and the ultimate defeat of the Provisional Government in the October Revolution, the Finnish Parliament decided to create a three-man regency council, based on Finland's Constitution, and more precisely on §38 of the old Instrument of Government of 1772, which had been enacted by the Estates after Gustav III's bloodless coup. This paragraph provided for the election of a new monarch in case of the extinction of the royal line and was interpreted in Finland as vesting sovereignty in the Estates, later the Parliament, during such an interregnum. The regency council was never elected, however, because of the strong opposition of Finnish socialists and their general strike of 1917
