And Gene Sharp, a lifelong advocate of nonviolent resistance, has died at the age of 90. Sharp was most famous for his extensive writings on nonviolent struggle, which include the influential book “From Dictatorship to Democracy: A Conceptual Framework for Liberation.” He was also the founder of the Albert Einstein Institution, which is dedicated to advancing the study of nonviolent action. This is Gene Sharp accepting the Right Livelihood Award in 2012.

Gene Sharp: “Nonviolent struggle, or nonviolent action, includes three categories of methods, specific means of acting. One, the methods of nonviolent protest, that are symbolic activities, such as marching down the street or displaying certain colors. But this technique, if it has only that, wouldn’t be worth much. It also includes the much more powerful methods of noncooperation, such as social boycotts, economic boycotts, labor strikes, political boycotts, civil disobedience. And thirdly, the methods of nonviolent intervention and disruption, such as sit-ins, fasts and the creation of new institutions.”

Gene Sharp died Sunday at the age of 90 in his home in Boston.
