The Arab Spring began on December 17, 2010, with Mohamed Bouazizi's self-immolation in Tunisia, leading to widespread protests across various Arab nations. Key events include the ousting of Ben Ali in Tunisia, violent clashes in Egypt resulting in Hosni Mubarak's resignation, and ongoing conflicts in Libya, Yemen, and Syria. By April 2013, the Arab Spring is described as ongoing, with significant political upheaval and humanitarian crises throughout the region.
