What was a significant event that occurred in Tunisia prior to the Arab Spring protests?

The significant event that occurred in Tunisia prior to the Arab Spring protests was the self-immolation of Mohamed Bouazizi. This act of protest, driven by despair over police harassment and the lack of economic opportunities, served as a catalyst for widespread protests against the government. Bouazizi's sacrifice resonated with many Tunisians who shared similar grievances, and it galvanized the population to take to the streets demanding political and social change. This powerful event highlighted the underlying issues of unemployment, corruption, and oppression, which contributed to the broader movement known as the Arab Spring, spreading to other countries in the region.

In contrast, the establishment of a new government, democratic elections, and international sanctions occurred as a response to the protests or in the context of later developments rather than preceding the protests themselves.
