Eight people died after protesters clashed with police using tear gas and water cannons.
In the wake of the protests, Erdogan said social media, which had played a role in coordinating protests and spreading information, was "the worst menace to society."
25 protesters were arrested for using Twitter and for "spreading untrue information."
10 months later, in March 2014, Erdogan banned Twitter for two weeks.
After the protests subsided, Erdogan faced a new problem after a voice recording allegedly showed him ordering his son to dispose of vast amounts of cash. Erdogan said the tapes were fake.
