Etymology
The area around Ahmedabad has been inhabited since the 11th century, when it was known as Ashaval. At that time, Karna, the Chaulukya (Solanki) ruler of Anhilwara (modern Patan), waged a successful war against the Bhil king of Ashaval, and established a city called Karnavati on the banks of the Sabarmati.
In 1411, this area came under the control of Muzaffar Shah I's grandson, Sultan Ahmed Shah, who selected the forested area along the banks of the Sabarmati river for a new capital city. He laid the foundation of a new walled city near Karnavati and named it Ahmedabad after himself. According to other versions, he named the city after four Muslim saints in the area who all had the name Ahmedabad.
