It’s been two years since the terror attack on Charlie Hebdo, but it feels more like two hundred.

After two Muslim brothers stormed its offices at 10 Rue Nicolas-Appert in the centre of Paris and massacred 12 people, "Je suis Charlie" became the rallying cry of those who condemned the attack. Over the following days, 40 world leaders travelled to Paris to stand in solidarity with the French government. Across France, more than three million demonstrators took to the streets in a show of unity against those who sought to reap terror. Charlie Hebdo’s following issue sold almost eight million copies.
