The cursus publicus, established by the Roman Empire to connect all its conquered territories, may be considered to be the ancestor of all modern post offices. Therefore, mail service networks are part of an organization, dating from Antiquity, which is common to the entire European community.

Second, the development of the system’s ability to deal with increasing traffic (through broader human resources). Thirdly, the diversification of its operations and the development of its technical modernisation.
