Ancient & modern

WHAT is it in our interests to do about immigration? The ancient Athenians came up with an interesting answer.

The reason for Athens' control of immigrants (metoikoi, 'those who change their habitation', metics) was suspicion of aliens (war being endemic in the ancient world) and paranoia about the purity of their own citizenship. Any nonAthenian who wanted to take up residence in Athens, temporary or permanent, had to fulfil certain conditions. First, they registered with the state authority; then they registered with the local authority (the 'cleme, roughly 'parish') where they were living. These registers were kept for administrative purposes. They also had to pay a unique monthly tax, and were liable for military service, but they could not own land or take any political role.

But there was another requirement, too: intending metics had to find themselves a citizen sponsor (prostates), both to support their application for metic status in the first place and (possibly) to continue to 'sponsor' them in some way or other when it had been granted. Indeed, a specific case could be brought against any metic thought not to have a prostates, the penalty for which was enslavement.

The purpose of all this was to ensure that metics did not get ideas above themselves. It was a privilege for them to live in Athens, and they were welcome enough, but on strictly subordinate terms. That, however, did not prevent them from coming. Athens was a powerful, flourishing, 'international' city: there was money to be made from being part of it. Since metics could not own land, they started up businesses in Athens and especially its harbour area, Piraeus, a prolific trading centre. Success combined with decent, orderly, law-abiding behaviour reaped its rewards in social mobility. The renowned orator Lysias was a metic who made his money writing speeches for others; his father, Cephalus, a Syracusan by birth, made a huge fortune from arms-manufacture in Athens (Plato's famous dialogue The Republic was set in his house); intellectuals like Protagoras flocked to Athens to make money there as teachers.

The purpose of the ancient state was to protect and advance the interests of its own citizens, not anyone else's. It dealt with aliens purely on the basis of the advantages they could bring, which could be many. The concept of a sponsor, perhaps to go bail for good behaviour, is particularly interesting.
