History
Protectorates are one of the oldest features of international relations, dating back to classical antiquity. The Delian League, Classical Athens's empire, operated as a network of poleis, internally self-governing but surrendering their foreign policy to Athens. Likewise, the Roman Republic had an extensive network of protectorates, known as socii, which provided up to 60% of the Republic's manpower.
