The Ancient Sakas in India had introduced Satrap system of government, along with Parthians, which was quite similar to the Iranian Achaemenid and Seleucid. Under this system, the kingdom was divided into provinces, each under military governor Mahakshatrapa (great satrap). The governors of lower status were called kshatrapas (satraps). These governors had the power to issue their own inscriptions and mint their own coins. According to the modern literature the term 'Satrap' used metaphorically to refer to as world leaders or governors who are heavily influenced by larger world superpowers or hegemonies and act as their surrogates.

As the head of the administration of province, the satrap collected taxes and was the supreme judicial authority; they were responsible for internal security and , raised and maintained an army.
