Tunisia was the one that started it all. When Mohammed Bouazizi set himself on fire in December, it's unlikely he intended to spark a regional upheaval. Protests about unemployment, high food prices and other domestic problems continued at a low level for weeks, exploding in mid-January. In a matter of days, then-President Zine al-Abidine Ben Ali fled the country. Tunisia is now trying to cobble together a provisional government to lead the country until it can hold its first free election in years later this year.
