Mäntsälä rebellion in the context of "Lapua Movement"

Pehr Evind Svinhufvud af Qvalstad (Finland Swedish: [ˈpæːr ˈeːʋin(d) ˈsviːnhʉːʋʉd ɑːv kʋɑːlstɑːd], 15 December 1861 – 29 February 1944) was the 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.

From December 1917, Svinhufvud was the first head of government of independent Finland as Chairman of the Senate. He led the White government during the Finnish Civil War while Mannerheim led their armies. After the war, he served as Finland's first temporary head of state with the title of Regent during the project to establish a German-aligned monarchy in the country, until late 1918 when he stepped down in favour of Mannerheim. He later served as Prime Minister from 1930 to 1931, before being elected to the presidency. As president, he was notable for putting an end to the Mäntsälä rebellion.
