Civil Protest
If a city descends into Civil Protest, it will stop generating its resource, buildings in it will cease working. If the protest is left unattended, buildings will be destroyed by angry mobs, and the very worst case scenario is that the city will defect to a neighbouring nation (this won't happen for the capital city). To avoid Civil Protest, keep your citizens content, don't overwork them, and build the Stadium and Police Station improvements in cities which you think could be in danger of Civil Protest.
