This collection documents political and violent forms of anti-Catholic prejudice in the United States during the nineteenth century. This collection was artificially created. The bulk of the material dates from the 1844 to 1888. Materials documenting violence against Catholics include an account of the burning of the Ursuline Convent in Charlestown, Massachusetts in 1834; a biography of an Ursuline nun; a student essay on the Ursuline Convent from 1930; and a piece of correspondence giving an account of the anti-Catholic riots in Pennsylvania. In addition, the collection contains material relating to the American Party. This includes party constitutions, records books, membership lists, and meeting minutes.
