Many similarities exist between the new movements against austerity that have emerged since 2011, ranging from Taksim Square in Turkey to the Chilean student protests, and from Greece to NYC. One of them is their return to the principles of direct democracy and their organization around popular assemblies. These ideas are hardly new – Murray Bookchin, who is one of the leading anarchist thinkers of the twentieth century, has been elaborating ideas about popular assemblies for several decades that have influenced thinkers such as David Harvey. The Next Revolution brings together Bookchin’s writings on popular assemblies for the first time, just as his ideas are rekindling the radical imagination worldwide.
