The year 1989 was a tumultuous one around the world, and it say the fall of Communist states in Europe. While not all were gone by the end of the year, Poland, East Germany, Romania, Bulgaria, and Czechoslovakia all were the site of challenges to Communist authority. These events were not lost on many Chinese, who also desired democratic and capitalistic changes. These desires eventually led to what became known as the Tiananmen Square Protests, and eventually led to the massacre of countless protestors at the hands of the Chinese military.</h2>
