Social movements are behind the most powerful changes in the world – from voting rights to political upheavals to the fight for racial equality. But how do you build a movement that unites millions of people and captures the attention of those in power? This episode of the World Economic Forum’s #ExpertsExplain series delves into the art of creating successful social movements with #HahrieHan, Professor of Political Science at #JohnsHopkinsUniversity. Han is also Inaugural Director of #SNFAgora Institute, using data and research to realise the promise of democracy all over the world, and an award-winning member of the Schwab Foundation for Social Enterpreneurship.
