The Bicholim Conflict of 1640–1641 was a period of armed conflict between the Portuguese rulers of Goa and the Maratha Empire led by Shivaji Bhonsle in the northern regions of Goa, particularly in the Bicholim region. The conflict lasted from mid-1640 to early 1641, when the Maratha Confederacy and the Portuguese signed a treaty by which they would respect the pre-existing Maratha–North Goa boundary. However, the conflict continued to cause tension between the Maratha rulers and the Portuguese in Goa and the islands of Daman and Diu. While the conflict mainly remained localised to Northern Goa, at one point anti-Portuguese uprisings occurred in the neighbouring regions of Pernem and Bardez.
