The Moscow Peace Treaty was signed by Finland and the Soviet Union on March 12, 1940, and the ratifications were exchanged on March 21. It marked the end of the 105-day Winter War. The treaty ceded parts of Finland to the Soviet Union. However, it preserved Finland's independence, ending the Soviet attempt to annex the country. The treaty was signed by Vyacheslav Molotov, Andrey Zhdanov and Aleksandr Vasilevsky for Soviet Union, and Risto Ryti, Juho Kusti Paasikivi, Rudolf Walden and Väinö Voionmaa for Finland.
