Ranked by the University of Pennsylvania's 2014 Global Go To Think Tanks Index Report as the second most influential think tank in the world (after the Brookings Institution), Chatham House has been contributing to expert thinking on international issues since its founding in 1922. The Social Movement section of the site concentrates its attention on everything from power struggles in Saudi Arabia to tribalism in South Sudan. Readers may scout the site by categories such as Latest, Expert Comment, Research & Publication, Past Events, and Video & Audio. There is a tremendous volume of content here. For instance, there are over 250 (and counting) research papers that are freely accessible, including reviews of democracy in Kuwait, Islam in Russia, and the legacy of France's colonialism as it plays out in Paris's suburbs. For readers fascinated by social movements, and looking for a reliable, informed source for in-depth information, Chatham House provides great resources.
