A spate of large-scale street protests around the world, from Chile and Hong Kong to Lebanon and Barcelona, is fuelling a search for common denominators and collective causes. Are we entering a new age of global revolution? Or is it foolish to try to link anger in India over the price of onions to pro-democracy demonstrations in Russia?
Each country’s protests differ in detail. But recent upheavals do appear to share one key factor: youth. In most cases, younger people are at the forefront of calls for change. The uprising that unexpectedly swept away Sudan’s ancien regime this year was essentially generational in nature.
