Punjab was the first permanent home of the Aryans when they entered India. The region known as Sapta Sindhu (land of seven rivers) - comprising Punjab and parts of neighboring areas - is described in the Rigveda as the earliest Aryan settlement. The fertile plains of Punjab, with its five rivers (Jhelum, Chenab, Ravi, Beas, and Sutlej), provided ideal conditions for the agricultural Aryans to settle before they expanded eastward.
