Alexei Navalny was one of the few remaining voices in Russia who gave President Vladimir Putin cause for alarm. One of the Kremlin’s most vocal critics, he was a media-savvy anticorruption activist who managed to breathe life into Russia’s opposition movement, exposing the flaws of Putin’s decadeslong rule on his popular YouTube channel despite never being able to challenge him at the ballot box. The popularity of his videos, usually detailing the corruption of Russia’s elite, set him apart from others in Russia’s fragmented opposition and gave him a nationwide following that he successfully called on to protest in the streets of Moscow and Russia’s other biggest cities.
