The Geomori or Geomoroi (Ancient Greek: γεωμόροι) were one of the three classes into which Theseus is said to have divided the inhabitants of Attica.
It is also not known whether an individual can transcend or be demoted to another class, such as the case of the poorer nobles who might have fallen into the ranks of the geomori.
[3] The term geomori may either signify independent land-owners, or peasants who cultivated the lands of others as tenants.
It seems, however, inconsistent with the state of affairs in Attica, as well as with the manner in which the name geomoroi was used in other Greek states, to suppose that the whole class consisted of the latter only; there were undoubtedly among them a considerable number of freemen who cultivated their own lands, but had by their birth no claims to the rights and privileges of the nobles.
There are sources, however, such as Aristotle whose works indicated that the class divisions by Theseus marked the modification to the constitution in the direction of popular government.
