2011 was a year of global tumult, marked by widespread social and political uprisings, economic crises, and a great deal more. We saw the fall of multiple dictators, welcomed a new country (South Sudan), witnessed our planet's population grow to 7 billion, and watched in horror as Japan was struck by a devastating earthquake, a tsunami, and a nuclear disaster. From the Arab Spring to Los Indignados to Occupy Wall Street, citizens around the world took to the streets in massive numbers, protesting against governments and financial institutions, risking arrest, injury, and in some cases their lives. Collected here is Part 3 of a three-part photo summary of the last year, covering 2011's last months. Be sure to also see Part 1, and Part 2, totaling 120 images in all. [40 photos]

Occupy Wall Street protesters march and hold signs in New York City on September 17, 2011.
