This is a list of the client rulers of Ancient Rome, sectioned by the kingdom, giving the years the ruler was on the throne, and separating Kings and Queens.
Rome's foreign clients were called amici populi Romani (friends of the Roman people) and listed on the tabula amicorum (table of friends).
They did not sign treaties or have formal obligations, but entered into alliance (societas) and friendship (amicitia) with Rome, generally in a dependent state.
