Change can and does happen. But why is it that some campaigns succeed while others fail? In “Counterpower: Making Change Happen,” British author and activist Tim Gee takes a look at the strategies and tactics that have contributed to the success (or otherwise) of some of the most prominent movements for change of the past 300 years, and finds some lessons for campaigners today. “Counterpower” was nominated for the Bread and Roses Prize for radical nonfiction.
