What a difference a year makes. It's hard to believe that this time in 2011, the world was abuzz over the Arab Spring. Flying in the face of the "death of history" narrative, the Arab Spring shocked the world by overturning some of its most entrenched authoritarian governments. Soon after, Occupy Wall Street became the American protest movement, both inspired by actions in the Arab world, as well as urging young Arabs on to further action. It seems pretty safe to say that the 21st century will definitely be interesting times; the protest movements have little sign of letting up any time soon. Revolutions and uprisings spread like wildfire once they reach critical mass. Here are five places to look for social unrest, mass protests and perhaps even another Bastille Day.
