It is the commercial hub of the state of Gujarat, though it is not the state capital, which is its twin city Gandhinagar, 30 km to the north. Although it is not very well known as a 'tourist' place, it is certainly worth a visit. Actually, the fact that there are fewer tourists will often get you a warmer welcome here. Also Gujaratis are known for their hospitality.
The city was founded by King Karandev 1 in the 11th century and originally called "Karnavati". The Hindu kingdom of Karnavati ruled for more than 400 years until 1411 when Sultan Ahmed Shah conquered Gujarat and the city was renamed Ahmedabad after him. The city was built in open and spacious plains to the East of Sabarmati. It was comprised of a little known installation known as Bhadra Fort. The city fort wall was enclosed containing 12 Gates. The city of Ahmedabad went on expanding in every direction by the addition of new areas on the sides of the river, with well laid out beautiful buildings, lakes and mosques. In 1753 the combined armies of Raghunath Rao and Damaji Gaekwad took the fort, which resulted into end of Mughal Rule in Ahmedabad. In 64 years during the rule of Gaekwad and Peshwa, city became cleaner. In 1818 the British annexed Ahmedabad via cunning. During this period the municipality committee was founded and a railway link was established.
