Located in the heartland of Central Asia - they are similar yet very different nations. Both nations use the similar colours of green, Turkish Blue, green, red and white. The Azeri and Uzbeki people are both Turkish peoples with different tilts. Azerbaijani are Turks at Europe's twilight while Uzbekistani are Turks at the edge of China's afterglow. During the Cold War they were drafted into the Soviet Union. And 700 years earlier they were annexed into the Mongol Empire. Islam of the domestic Sunni temperament. Nothing like Russia, China, India or Arabia they are the cultural monkeys in the middle.
