The rights, on the contrary, which were secured by the federal treaties to the individual burgess of one of the allied communities in every city belonging to the league, underwent no restriction.
These included, in particular, full equality of rights as to the acquisition of landed property and moveable estate, as to traffic and exchange, marriage and testament, and an unlimited liberty of migration; so that not only was a man who had burgess-rights in a town of the league legally entitled to settle in any other, but whereever he settled, he as a right-sharer (-municeps-) participated in all private and political rights and duties with the exception of eligibility to office, and was even--although in a limited fashion --entitled to vote at least in the -comitia tributa-.(6)
6. Such a --metoikos-- was not like an actual burgess assigned to a specific voting district once for all, but before each particular vote the district in which the μέτοικοι were upon that occasion to vote was fixed by lot. In reality this probably amounted to the concession to the Latins of one vote in the Roman -comitia tributa-. As a place in some tribe was a preliminary condition of the ordinary centuriate suffrage, if the μέτοικοι shared in the voting in the assembly of the centuries-which we do not know-a similar allotment must have been fixed for the latter. In the curies they must have taken part like the plebeians.
