P. E. Svinhufvud becomes the chairman of his first senate, technically the first Prime Minister of Finland.

Pehr Evind Svinhufvud af Qvalstad was the third president of Finland from 1931 to 1937. Serving as a lawyer, judge, and politician in the Grand Duchy of Finland, which was at that time an autonomous state under the Russian Empire’s rule, Svinhufvud played a major role in the movement for Finnish independence. He was the one who presented the Declaration of Independence to the Parliament.

Pehr Evind Svinhufvud's first senate was the first Senate and de facto Government of independent Finland. Its term spanned November 27, 1917 – May 27, 1918.

The prime minister of Finland is the leader of the Finnish Government. The prime minister and their cabinet exercise executive authority in the state. The prime minister is formally ranked third in the protocol after the president of Finland and the speaker of the Parliament but is in practice the most powerful office-holder. Finland's first prime minister, Pehr Evind Svinhufvud, was appointed on 27 November 1917, just a few days before the country declared its independence.

November 27 is the 331st day of the year in the Gregorian calendar; 34 days remain until the end of the year.
