During the 18th century, the Maratha Empire grew quickly, conquering Konkan and much of eastern Gujarat from the Mughal Empire. In western Gujarat, including Kathiawar and Kutch, the weakening Mughal control allowed lots of local rulers to become independent. The first battle between the British and the Marathas was the First Anglo-Maratha War which began in 1774 and resulted in the 1782 treaty of Salbai. The treaty meant that the island of Salsette, next to Bombay island, was given to the British. The British took over Surat in 1800. British territory became bigger in the Second Anglo-Maratha War which ended in 1803.
