Perioeci

The perioeci, or perioikoi, were the members of an autonomous group of free but non-citizen inhabitants of Sparta. Concentrated in the beach and highland areas of Laconia, the name περίοικοι derives from περί / peri, "around," and οἶκος / oikos, "dwelling, house." They were the only people allowed to travel to other cities, which the Spartans were not, unless given permission.
