During the Roman Republic, there were watchmen that served as firefighters. They used water buckets to put out fires and axes to tear down buildings near the fire in order to prevent the fire from spreading. The aediles and tresviri nocturni were also employed to fight fires. Roman Emperor Augustus created the Vigiles. The Vigiles were an organization of freedmen that fought fires. They would use buckets and water pumps. Emperor Nero also created "bucket brigades" to help fight fires.
