Alexei Navalny was Russia's most prominent and effective opposition leader, an anti-corruption crusader and democratic politician who entered public life as a provocative blogger around the same time his future persecutor, Vladimir Putin, became Russia's president. Navalny died inside an Arctic penal colony on Feb. 16. He was 47. He leaves a legacy, setting an example of how to challenge the regime even while under constant state persecution. In this episode, Miriam Lanskoy of the National Endowment for Democracy explains who Navalny was, why his opposition movement was so effective, and what his death says about late Putinism.
