January 25, 2012 marks the one-year anniversary of the start of the revolution in Egypt that eventually toppled President Hosni Mubarak's regime. The hotbed of the revolution, Tahrir Square, became the focal point of worldwide attention, and became the highest-profile event in the entire Arab Spring.
