The emirate system of administration can be likened to a constitutional monarchy.
The governments of the emirates were completely centralized. The Emirs controlled the Executive Legislative and Judicial powers of the emirates.
The Emirs who were the political, administrative and spiritual leaders appointed a number of officials assigned with specific duties, in the same way Queen of England has a prime minister and ministers for different ministries. For instance Waziri - The Prime Minister of the Emirate.
Sarkin Fada - The spokesman of the Emirate Sarkin Ruwa - Minister in charge of water Resources etc.
