Romanization in the province of Asia did not manifest itself in linguistic or cultural changes, but is very visible in a trend towards corporate organization. In the cities of western and southern Phrygia, professional associations developed that were able to gain a prominent position alongside the civic institutions. It is possible to relate this process to incentives provided by Roman law. In the villages surrounding these cities, and especially in the rural areas of northern and eastern Phrygia, the conditions were different, but there are several indications that a new preference for formal organization and its epigraphic representation developed here as well.
