The Ibanag originated in the region around the mouth of the Cagayan River and gradually dispersed southward within the last 200 years, influencing groups like the Itawis, Isinay, and Gaddang. Ibanag is the lingua franca for trade in the area. They were influenced to grow tobacco by the encroaching Ilokano from the west coast.
