Kay Larson´s insightful account of the contributions made to our nation by Anna Ella Carroll redresses a major inequity in the historiography of nineteenth-century America. Carroll played an important role in Maryland politics and was instrumental in efforts to keep that state in the Union in 1861. As a major force in Maryland politics, Carroll was a close confidante of that state´s leading politicians.
