It was exactly 75 years ago, when Yalta — a seaside resort on Russia's Black Sea Crimean coast — became the scene of a memorable summit between the "Big Three" Allied leaders: Winston Churchill, Franklin D. Roosevelt and Joseph Stalin. Held between Feb. 4-11, 1945, the conference helped devise the final strategy of the war against Nazi Germany and Japan.

Ultimately, the summit would find a controversial place in 20th-century history, when the World War II "allies of convenience" drew the lines of Europe's future map, which became the effective borders of the Cold War world.
