A year ago, 26-year-old Mohamed Bouazizi was getting ready to sell fruits and vegetables in the rural town of Sidi Bouzid, Tunisia.
Bouazizi was the breadwinner for his widowed mother and six siblings, but he didn't have a permit to sell the goods. When the police asked Bouazizi to hand over his wooden cart, he refused and a policewoman allegedly slapped him.
Angered after being publicly humiliated, Bouazizi marched in front of a government building and set himself on fire.
