 Libya's revolution is also considered part of the Arab Spring, beginning February 15, 2011, just a few months after the events in Tunisia.The revolution deposed Muammar Gaddafi, who had been the ruler of Libya for four decades and had united the country under the themes of Pan-Arabism (a form of nationalism), common geography, shared history, and Islam.The revolution was an attempt to replace these forms of legitimacy with democratic legitimacy via the National Transitional Council.
