Egypt's 'Arab Spring' uprising began one-year-ago Wednesday.
Following the overthrow of Tunisia's dictator, Egyptians took to the streets in the hundreds of thousands. They occupied Tahrir Square in a protest that finally brought down the regime.
Then the unrest spread -- to Libya, Bahrain, Syria, and beyond. And some say the occupation of Tahrir Square inspired the Occupy Wall Street encampments and protests in this country.
