So far, I have been taking 2 history courses [1][2] on coursera.org (which offers over 300 free online courses) and I can certainly recommend both of them. Each course looks like this: about 2 hours of video lectures per week (which you can watch whenever you want), over a period of ~15 weeks. Clearly, following those history courses meant that I do not see the world with the same eyes now. For one, I feel that I am developing a (healthy) reflex to view news events in perspective within a longer period of time, instead of just considering the events in themselves (thus lacking context). Also, drawing parallels with similar events in the past provides insight and offers a wider and more informed framework for devising an appropriate action.
