On this day in 1955 Disneyland theme park opened in Anaheim, California. Some might have seen it as Walt Disney's scheme to cash in on his animated film empire, but after seeing it first hand I'll have to admit that it is quite possibly the happiest place on earth. Big thunder mountain railroad is pretty badass, and getting your picture taken when you go over that edge on splash mountain is really cool.
On this day in 1918 the deposed Czar Nicholas II and the rest of the Romanov family are killed by Bolsheviks. The Russian revolution was a direct result of WWI and the populous of the largest country in the world were sick and tired of being down trodden. They took to the streets in 1917 and forced the abdication of the Czar. The Bolsheviks felt as long as there was an heir to the the Romanov dynasty alive then there would still be a chance that people would rally behind the Czar. So in the middle of the night they rounded up the entire family and shot them.
On this day in 1945 the Potsdam conference occurred with the final meeting between the leaders of the allied powers of WWII. It was supposed to put a plan in place of how to divide the spoils of Europe, how to rebuild the war torn continent, and what would be done to defeat the Japanese. Stalin came away the big winner when he was able to put forth a plan that would put all of eastern Europe under his control in at least a small way. It was here that Russia decided to also finally attack Japan, despite a non-aggression pact.
