History:
Archaeological evidence suggests that the area around Ahmedabad has been inhabited since the 11th century, when it was known as Ashapalli or Ashaval. At that time, Karandev I, the Solanki ruler of Anhilwara (modern Patan), waged a successful war against the Bhil king of Ashaval and established a city called Karnavati located at the present time area of Maninagar close to the river Sabarmati. Solanki rule lasted until the 13th century, when Gujarat came under the control of the Vaghela dynasty of Dholka and Karnavati was conquered by the Sultanate of Delhi. In 1411, the rule of the Muzaffarid dynasty was established in Gujarat. According to legend, Sultan Ahmed Shah, while camping on the banks of the River Sabarmati, saw a hare chasing a dog. Impressed by this act of bravery, the Sultan, who had been looking for a place to build his new capital, decided to locate the capital at this forest area close by to Karnavati right on the river bank and christened it Ahmedabad.
The incident is popularly described in a one liner saying "Jab kutte pe sassa aaya, tab Badshah ne shaher basaya". When the hare chased the dog, seeing that act of bravery then the Emperor built the City.
Ahmedabad became the capital of the new state of Gujarat after the bifurcation of the State of Bombay  on 1 May 1960. During that period, a large number of educational and research institutions were founded in the city, making it a major center of  higher education, science and technology. Ahmedabad's economic base was diversified with the establishment of heavy  and  chemical industries  in its vicinity around the same period. But the growth in the next two decades was punctuated by political events in and around the city. In 1974, Ahmedabad occupied the centre stage in national politics with the launch of the  Nav Nirman  agitation — a protest against a 20% hike in the hostel food fees at the  L.D. College of Engineering  that snowballed into a mass agitation against general corruption to remove Chimanbhai Patel, then-chief minister of Gujarat. In the 1980s, a reservation policy was introduced in the country, which led to anti-reservation protests in 1981 and 1985. The protests witnessed violent clashes between people belonging to various  castes. On 26 January 2001 a devastating earthquake  struck the city, centred near Bhuj, measuring 6.9 on the Richter scale. As many as 50 multistory buildings collapsed, killing 752 people and devastating the city's infrastructure. The following year, Gurajat violence  between Hindus and Muslims spread to Ahmedabad, paralysing the city for more than a month. The crisis resulted in the deaths of an estimated 1,044 people across the state. The displacement of thousands of Muslims led to the erection of refugee camps around the city. On 26 July 2008 a series of seventeen bomb blasts  rocked the city, killing and injuring several people.
