Srdja Popovic is the founder and executive director of the Center for Applied Nonviolent Actions and Strategies (CANVAS), a non-profit organization based in Belgrade, Serbia, that aims to teach the use of nonviolence to make a change. 

He was born and raised in Belgrade, Serbia (then part of Yugoslavia), in 1973. Popovic played the guitar in a rock band and graduated from the Faculty of Biology in Belgrade, holding a master's degree (MA) in animal ecology. Since his early 20s, he has focused on activism, democracy, and human rights issues. 

In 1998, Popovic founded the student movement "Otpor!" ("Resistance!"), which played a crucial role in ousting president Slobodan Milosevic, former Serbian dictator accused of war crimes. After Milosevic was defeated in 2000, Popovic was elected to the Serbian parliament, where he served from 2000 until 2004. 

Following his career in the parliament, Popovic went on to found CANVAS, acting as its executive director ever since. CANVAS was created with the intent of teaching people all over the world about how to be successful in nonviolent conflict. So far, the organization has worked with activists from 46 different countries, spreading the knowledge of the nonviolent strategies and tactics used by Otpor! worldwide.
