Punjab grew out of the settlements along the five rivers, which served as an important route to the Near East as early as the ancient Indus Valley civilization, dating back to 3000 BCE, followed by migrations of the Indo-Aryan peoples. Agriculture has been the chief economic feature of the Punjab and formed the foundation of Punjabi culture. The Punjab emerged as an important agricultural region, especially following the Green Revolution during the mid-1960s to the mid-1970s, and has been described as the "breadbasket of both India and Pakistan."
