In 2011, TIME named the Protester as the Person of the Year, in recognition of the twin people-power earthquakes of the Arab Spring and Occupy Wall Street. TIME named the Ebola Fighters as the 2014 Person of the Year, but you could have forgiven if we went back to the Protester. There wasn’t a corner of the planet untouched by protest this year, from the tear-gassed streets of Ferguson, Missouri, to the squares of Mexico City, to the impromptu student camps of Hong Kong. Many of the protests were remarkably peaceful, like Occupy Hong Kong, which was galvanized by public anger over the overreaction of the city’s police. Others turned bloody, like the Euromaidan protests in Kiev, Ukraine, which eventually brought down the government of pro-Russian Ukrainian President Viktor Yanukovych, in turn triggering a war that led to the annexation of Crimea by Russia, the downing of Malaysia Airlines Flight 17 in May and the deaths of thousands of Ukrainians.

Not every protest was as effective as those that began the year in the cold of Kiev. Hong Kongers still don’t have full democratic rights, gay rights are on the retreat in much of east Africa and every day seems to bring news of another questionable police killing in the U.S. But the wave of social action that ended 2014 is unlikely to crest in 2015. The ubiquity of camera phones means no shortage of iconic photographs and videos from any protest, whether in Lima or Los Angeles, and social media gives everyone the means to broadcast. What follows are some of the most powerful images from the global streets in 2014.
