World War 2 Events by Country - Finland


Listing of all day-by-day events of the Second World War related to the nation of Finland.

World War 2 spanned across language barriers, cultures, and borders as it wreaked havoc around the globe. The conflict was made up of several major theaters - spanning nearly all oceans and continents - which contained many individual campaigns and, within these, key battles and events on both the military and political spectrums. The war was fought with equal fervor and verocity across the land, on the sea (and under it), and in the air as millions of men and women answered the call of their respective flags - or happened to find themselves in the war's path with no option but to fight. In the end, the fractured world opened its eyes to a new order - one that would usher in a whole new trial in the Cold War and lead to the establishment of dozens of independent countries heading towards the end of the century.
