Overview
Baron Carl Gustaf Emil Mannerheim (, ; 4 June 1867 – 27 January 1951) was a Finnish military leader and statesman. He served as the military leader of the Whites in the Finnish Civil War (1918), as Regent of Finland (1918–1919), as commander-in-chief of the Finnish Defence Forces during the period of World War II (1939–1945), and as the sixth president of Finland (1944–1946). He became Finland's only field marshal in 1933 and was appointed honorary Marshal of Finland in 1942.
The Russian Empire dominated the Grand Duchy of Finland before 1917, and Mannerheim made a career in the Imperial Russian Army, serving in the Russo-Japanese War and the Eastern Front of World War I and rising by 1917 to the rank of lieutenant general. He had a prominent place in the ceremonies for Emperor Nicholas II's coronation in 1896 and later had several private meetings with the Tsar. After the Bolshevik revolution of November 1917 in Russia, Finland declared its independence (6 December 1917) – but soon became embroiled in the 1918 Finnish Civil War between the pro-Bolshevik "Reds" and the "Whites", who were the troops of the Senate of Finland, supported by troops of the German Empire.
A Finnish delegation appointed Mannerheim as the military chief of the Whites in January 1918, and he led them to victory, holding a triumphal victory parade in Helsinki in May. After spending some time abroad, he was invited back to Finland to serve as the country's second regent, or head of state, from December 1918 to July 1919. Despite being a monarchist, he formally ratified the republican Constitution of Finland. He then ran against K. J. Ståhlberg in the first Finnish presidential elections in 1919 but lost and quit politics. Mannerheim helped found the Mannerheim League for Child Welfare in 1920 and headed the Finnish Red Cross from 1922 to his death. He was restored to a central role in national defence policy when President Svinhufvud appointed him as the Chairman of the Finnish Defence Council in 1931, tasked with making preparations for a potential war with the Soviet Union. It was also agreed that he would temporarily take over as commander-in-chief of the country's armed forces should there be a war.
Accordingly, after the Soviets invaded Finland in November 1939 in what became the Winter War, Mannerheim replaced President Kallio as commander-in-chief, and occupied the post for the next five years.
