The protests in Hong Kong began as a mass expression of frustration over a contentious bill. They have evolved into a violent fight over the future of this Chinese territory.

Tunnels, bridges and even the airport have been shut down. Campuses have become battlegrounds. Streets have been filled with smoke and tear gas. And thousands have been arrested.

To the protesters and their advocates, it all represents a movement to protect the city’s freedoms and defend democratic ideals.

To the government, the police and their supporters, it is a threat that is damaging the economy and undermining society.

Both camps are made up of individuals. Their motivations and perspectives differ. Their means vary. But they all have the same goal: defending their city.

These are the faces of the unrest.
