Four Weeks in Tahrir Square

The Egyptian military cleared Cairo's Tahrir Square of protestors on Tuesday, freeing the plaza for traffic for the first time in weeks after mass demonstrations eventually led to the end of President Hosni Mubarak's regime. Tahrir, which means "Liberation," had been the epicenter of the anti-government protests, with an elaborate occupation camp staffed by volunteers—from doctors and nurses to people running a lost-and-found stand.
