Finland's decision to initiate peace negotiations on February 29, 1940, marked a significant turning point in the Winter War, which had erupted on November 30, 1939, when the Soviet Union invaded Finland. The conflict stemmed from Soviet demands for territorial concessions, which Finland rejected. Over the course of three months, Finnish troops engaged in a fierce defense characterized by guerrilla tactics and superior knowledge of the terrain, prompting initial success against an invading army that was both larger and better equipped. Despite these efforts, by early 1940, the weight of Soviet military resources began to wear down the Finnish defenses. The situation became increasingly dire for Finland, with heavy casualties and a rapidly deteriorating economic landscape.As the Winter War progressed, Finland found itself in a precarious position. International support was limited, with many nations watching the conflict but hesitating to intervene directly. In light of these developments and the significant losses suffered, Finnish leadership recognized the necessity of seeking a diplomatic resolution. Thus, the initiation of peace talks was a strategic move reflecting both the need to preserve the state and the desire to conclude the conflict on terms that would minimize further territorial losses and suffering among its populace. The negotiations would lead to a ceasefire in March 1940, though Finland ultimately had to cede significant territories, including parts of Karelia and the important city of Viipuri, to the Soviet Union.
