The Finnish Declaration of Independence, adopted by the Parliament of Finland on 6 December 1917, marked the moment when Finland severed its constitutional ties with Russia and proclaimed itself a sovereign republic. The declaration is celebrated each year as Finnish Independence Day, but the road to that moment was neither simple nor swift. It was the culmination of a long and complicated political process that unfolded against the backdrop of revolutionary upheaval in Russia and deep ideological divisions within Finland itself.
The story begins with the collapse of the Russian imperial order. Following the February Revolution and the abdication of Tsar Nicholas II — who also held the title of Grand Duke of Finland — on 2 March 1917 in the old-style calendar, or 15 March in the new style, the personal union that had bound Finland to Russia since 1809 lost its constitutional foundation, at least according to the interpretation advanced in Helsinki. Finnish authorities entered into negotiations with the Russian Provisional Government over the future status of the grand duchy.
Out of those negotiations emerged a proposal that the Finnish Parliament fundamentally transformed. What the Provisional Government had initially approved was heavily rewritten in the Finnish legislature, the Eduskunta, and emerged as the so-called Power Act — Valtalaki in Finnish, Maktlagen in Swedish. The Power Act was a sweeping assertion of parliamentary sovereignty: it declared that the Finnish Parliament now held all legislative powers except in the areas of foreign policy and military matters, and crucially, that the Parliament could only be dissolved by itself, not by any external authority. The vote took place amid a widespread belief that the Provisional Government in Petrograd was about to fall; in the event, the Provisional Government survived, promptly disapproved of the Power Act, and dissolved the Finnish Parliament entirely.
New elections were held. Then, in the October Revolution, the Provisional Government was overthrown by the Bolsheviks. In this new environment, the Finnish Parliament moved to establish a three-man regency council based on the country's existing constitutional framework, drawing specifically on clause 38 of the old Instrument of Government of 1772, which had originally been enacted by the Estates following King Gustav III's bloodless coup of that year. This clause had provided for the election of a new monarch in the event of the royal line's extinction; Finnish jurists now interpreted it as vesting sovereignty in the Parliament during an interregnum. The regency council was never actually formed, however, because Finnish socialists and their allies organised a general strike demanding more radical political change.
The situation shifted decisively on 2 November 1917 in the old calendar, or 15 November in the new style, when the Bolshevik government issued a declaration affirming the right of all peoples of Russia to self-determination, including the right to full secession. On the same day, the Finnish Parliament issued its own declaration assuming all the sovereign powers of the state. The Senate of Finland, the government the Parliament had appointed in November, then drafted both a formal Declaration of Independence and a proposal for a new republican Instrument of Government, signalling that leading Finnish circles had long since abandoned any attachment to monarchism or hereditary nobility and were committed to a republican future.
The Chairman of the Senate — a title equivalent to prime minister — Pehr Evind Svinhufvud, read the Declaration to Parliament on 4 December 1917. Technically, the Declaration was given the form of a preamble attached to the larger legislative proposition, and it was formally adopted by Parliament two days later, on 6 December. The Declaration itself expressed the conviction that the Finnish people could no longer fulfil their national and international obligations without complete sovereignty, stating: "The people of Finland have by this step taken their fate in their own hands; a step both justified and demanded by present conditions."
International recognition came swiftly from an unexpected quarter. On 18 December in the old calendar, or 31 December in the new style, the Soviet Russian government became the first foreign government to recognise Finland's independence, issuing a formal decree. On 22 December old style, or 4 January 1918 new style, that recognition was confirmed by the All-Russian Central Executive Committee, known as the VTsIK. The speed and source of this recognition carried its own historical irony: the same Bolshevik revolution that had swept away the old Russian order had, in its first weeks of power, granted Finland the freedom it had sought for generations.
