Examining the transatlantic writings and professional careers of Thomas Carlyle and Ralph Waldo Emerson, this book explores the impact of literary, cultural, political and legal manifestations of authority on nineteenth-century British and American writing, publishing and lecturing. Drawing on primary texts in conjunction with a rich body of archival sources, this study retraces Romantic debates about race and nationhood, analyses the relationship between cultural nationalism and literary historiography and sheds light on Carlyle's and Emerson's professional identities as publishing authors and lecturing celebrities on both sides of the Atlantic.
