[2] Ahmed Shah I laid the foundation of Bhadra Fort starting from Manek Burj, the first bastion of the city in 1411 which was completed in 1413.
His grandson Mahmud Begada transferred capital from Ahmedabad to Muhammadabad from 1484 to 1535 but carried out second fortification of the city.
In 1817, Ahmedabad fell under British Company rule which stabilized the city politically and improved the trade.
[4] The old city continued to be the centre of political activities during the Indian independence movement under Mahatma Gandhi.
Square in form, enclosing an area of about forty-three acres, the Bhadra fort had eight gates, three large, two in the east and one in the south-west corner; three middle-sized, two in the north and one in the south; and two small, in the west.
So the second fortification was carried out by Mahmud Begada in 1486, the grandson of Ahmed Shah, with an outer wall 10 km (6.2 mi) in circumference and consisting of 12 gates, 189 bastions and over 6,000 battlements as described in Mirat-i-Ahmadi.
Bhadra fort had eight gates, three large, two in the east and one in the south-west corner; three middle-sized, two in the north and one in the south; and two small, in the west.
This form of housing was established during a time of divided rule from 1738-1753 due to religious tension between Hindu and Muslims.
It signifies contributions to arts and crafts, traditions, and structure design, and is reflective of the city's occupants.
This is evident in the city being home to institutions belonging to several religions including Hinduism, Islam, Christianity, and Judaism.
