The ideals of the Arab Spring have attracted people from all around the globe.
Some have gone to support a rebellion, others have traveled to countries like Egypt, Libya and Tunisia full of hope.
Hope that in places where revolutions overthrew dictators, society would be different, and democracy would flourish.
The BBC's Shaimaa Khalil went back to Egypt, the country of her birth.
She headed first to her hometown of Alexandria to see what life there is like, two years after Egypt's revolution.
Khalil produced a series of documentaries,"Egypt's Challenge," describing the state of the transformation in the country, in a very personal way.
