Red, White or Black Russians

Over the years I have been asked if I knew what the difference between a Red, White and Black Russian was. So... I did some digging and found that besides names for very colorful drinks made from vodka. White and Red Russians were nicknames given the armies under the control the Communist and Tsarist groups during the Russian Civil War in 1917. The Communist forces were called the Red Army. The Tsarist forces were called the White Army. So the nicknames of White and Red Russians stuck. The first picture is of the Flag of the Red Army. The second picture is of the flag of the Imperial flag of the Russian Empire. The Black Russian is just a drink... no real historical ties that I could find.
