Roman Federation

[Kosmo]

Roman expansion left behind many cities or political entities that after defeat or as allies got the status of federated with Rome. Their obligations and rights varied greatly and Rome was not as centralised as it's usually believed. Some had a status that was later lost (like Tarent)

This structures were integrated in provinces, but kept their feodus. Something like princely states in British India.

What happened with those strucutres? What was the extent of their autonomy (budget, leadership, military, justice)? Was a province divided in federated areas and areas under direct control?

Julian the Apostate wrote to the senate of Athens and to that of Sparta so some existed even that late.
