Waves of Democracy [PDF ebook] 
Social Movements and Political Change, Second Edition

The second edition of this classic text covers contemporary democracy movements including the Arab Spring and its aftermath, Occupy, and new nations as well as old issues from the Balkans to Africa, from Latin America to Ukraine. The author has traveled widely around the world to take the pulse of transition and to profile journeys toward democracy and journeys away from democracy, too. At the same time, the book addresses important challenges that have emerged in even well-established democracies. These show up in declining voting rates, diminished membership in political parties, and, in some countries including the United States, negative views of central democratic institutions (like the US Congress).
