America was born in an age of political revolution throughout the Atlantic world, a period when the very definition of ‘nation’ was transforming. Benjamin E. Park traces how Americans imagined novel forms of nationality during the country’s first five decades within the context of European discussions taking place at the same time. Focusing on three case studies - Massachusetts, Pennsylvania, and South Carolina - Park examines the developing practices of nationalism in three specific contexts. He argues for a more elastic connection between nationalism and the nation-state by demonstrating that ideas concerning political and cultural allegiance to a federal body developed in different ways and at different rates throughout the nation. American Nationalisms explores how ideas of nationality permeated political disputes, religious revivals, patriotic festivals, slavery debates, and even literature.
