What led to the collapse of Zimbabwe

Welcome to Zimbabwe! You have entered a country in the middle of Chaos: violence is rampant, the economy has collapsed, and there appears to be no hope. You have been assigned to use your research skills to determine why Zimbabwe is collapsing so that the country may save itself. Over the next five days you will research and review information from five categories that pertain to the collapse:American History (how did the U.S. historically play a role leading to this event), World History (what historical factors lead to this event), Geography (what geographic factors helped the collapse) and Civics ( what role did civics play in the collapse). So you better hurry, you only have five days to save the nation!
