Peregrinus was the term used during the early
Roman empire, from 30 BC to 212 AD, to denote a free provincial subject of the Empire who was not a
Roman citizen.
Peregrini constituted the vast majority of the Empire's inhabitants in the 1st and 2nd centuries AD. In 212 AD, all free inhabitants of the Empire were granted citizenship by the
constitutio Antoniniana, abolishing the status of
peregrinus.
