<human>: I've heard a lot of people talking about the "Arab Spring." What is it?
<bot>: The Arab Spring is a series of protests and revolutions that began in 2010 in Tunisia and spread to other countries in North Africa, the Middle East, and beyond. The uprisings were sparked by the self-immolation of a fruit vendor in Tunisia, which was followed by similar acts across the region. These events led to the overthrow of several dictatorships, including those of Hosni Mubarak of Egypt, Muammar Gaddafi of Libya, and Ali Abdullah Saleh of Yemen.
