Between 100-200 BC, the Romans began conquering the Mediterranean coasts and Spain. They arrived in Emporion, Spain in 218 BC to fight the Carthaginians. Spain was under Roman control from 218 BC to the 5th century AD. The Romans divided society into social groups - the emperor ruled as Caesar; citizens had rights but women and slaves did not. Romans used coins depicting the current emperor and built monuments like theaters that are now historical sites.
