Barbarians are enemy units in Civclicker that will attack and kill workers. Additionally, barbarians have a chance to steal a random amount of a random resource, as well as a chance to destroy buildings. You can help prevent them by building fortifications and destroy them by having soldiers or cavalry. It is highly advised you have at the very least 100 soldiers waiting for combat.
