2013 was marked by mass actions in Turkey, Chile, Thailand, Cambodia, the Ukraine and many others. Egypt saw street protests become more divided and conflicting, as politically it began to grapple with what a post-Mubarak society should look like.
Gezi Park was a great example of how mass resistance can arise and turn a small, local dispute into a large scale response to national politics. Sometimes all there needs to be is an outlet, a location to rally around- the passion and anger is already there.
