With more than two decades of hindsight, it has become clear that 1989 marked a key turning point in world history. It is now possible to analyze the momentous events of 1989 in a historical fashion, and also to teach history classes about them. In fall 2010, 19 students in an undergraduate history seminar at Simon Fraser University in British Columbia embarked on a group writing project about the Tiananmen Square protests of 1989. Their original compositions were published at the end of the term as Wikipedia entries, and have already reached an audience of thousands. They are also archived online at the SFU Tiananmen Square Project.
