"Counterpower" is the single idea which explains why social movements succeed or fail. It has helped win campaigns, secure human rights, stop wars and even bring down governments. Activist, and author, Tim Gee seeks to get to the root of how change happens by taking an in-depth look at the strategies and tactics that have contributed to the success (or otherwise) of some of the most prominent movements for change from Indiaś Independence Movement to the Arab Spring. He concludes that any campaign is winnable in theory, but only if we are aware of our power.
