The Ursuline Convent riots occur on August 11 and 12, 1834, in Charlestown, Massachusetts, near Boston, in what is now Somerville, Massachusetts.
During the riot, a convent of Roman Catholic Ursuline nuns is burned down by a Protestant mob.
The event is triggered by reported abuse of a member of the order, and is fueled by the rebirth of extreme anti-Catholic sentiment in antebellum New England.
