The city of Bombay came in light in the year 150 A.D. through the geographical work of renowned geographer, Ptolemy. The city, consisting of several islands, was then ruled by Marathikolis and agris.
These natives ruled the islands up to 1345. Thereafter, Mumbai's rulers changed through history until Islamic rulers conquered what is now Maharashtra and conquered some of the islands in 1534. Subsequently, a Muslim sultan of Gujarat took over all the islands, which were then conquered by the Portuguese.
By a Royal Charter under the Regulation XIX of 1827, passed by the British Government, the Collector of Bombay was made the Chief Controlling Authority of the Revenue Administration of Bombay. The Collector of Bombay enjoyed vast authority under the Bombay Land Revenue Act 1876 which was repealed by the Maharashtra Land Revenue Code 1966.
