Ahmedabad is a one of the fastest devloping cities in India with large roads and notable architecture. This city was originally built on the banks of the river Sabarmati, but it has expanded since. In 1487 Mahmud Begada , the grandson of Ahmed Shah, enclosed the city with a fort of six miles in circumference and consisting of 12 gates , 189 bastions and over 6,000 battlements to protect it from outside invaders. Conditions in the city were chaotic by the time of the last Sultan, Muzaffar III, and Gujarat was conquered by the Mughal emperor Akbar in 1573 . During the Mughal reign, Ahmedabad became one of the empire's thriving centres of trade, especially in textiles, which were exported as far as Europe. A famine in 1630 devastated the city. In 1753 , the armies of the Maratha generals Raghunath Rao and Damaji Gaekwad captured the city and ended Mughal rule in Ahmedabad.
