In a three- to five-paragraph essay, explain which of the three periods you think was most important to world history. Your essay should describe the changes that took place during the period, as well as the short- and long-term effects on Europe and the rest of the world, and it should provide historical evidence supporting the period's importance. It should also include one paragraph explaining why the other two events are less important than the one you chose.
