International peacekeepers

We think these are a fairly modern invention - but they have been around for millenia. According to the Notitia Dignitatum [a Roman document from about 400AD], the Romans had auxilliaries from places as far apart as Iraq, Batavia, Algeria and Syria based at forts along Hadrian's Wall. Ironic though, that we have peacekeepers in Iraq now, whereas 2000 years ago, it was the Iraqis keeping the peace against the incursions of the Picts on the boundary of the Roman Empire.
