Arab Spring refers to the democratic uprisings that arose independently and spread across the Arab world in 2011. The movement originated in Tunisia in December 2010 and quickly took hold in Egypt, Libya, Syria, Yemen, Bahrain, Saudi Arabia, and Jordan.

On 15 October 2011, the subsidiary Occupy and Indignants movements inspired protests in 950 cities in 82 countries.he rebellion and coup have been described as fallout from the Arab Spring, as the success of the Tuareg rebellion where it had failed in previous efforts throughout the 20th century has been attributed largely to heavy weaponry carted out of Libya by Tuareg fighters on either side of the Libyan Civil War in 2011.
