 A major development of this period that would have a profound impact on Kannada literature even into the modern age was the birth of the Haridasa ("servants of Hari or Vishnu") movement.This devotional movement, although reminiscent in some ways of the Veerashaiva movement of the 12th century (which produced Vachana poetry and taught devotion to the god Shiva), was in contrast intimately devoted to the Hindu god Vishnu as the supreme God.The inspiration behind this movement was the philosophy of Madhvacharya of Udupi.
