Among the Civil War subfields that remain relatively underexplored is trans-Atlantic influences. Niels Eichhorn, an assistant professor at Middle Georgia State University, makes a fine contribution to that subfield with his book Liberty and Slavery, wherein he explores the relationship between southern secessionism and European separatism. He compares the separatist movements against brutal subjection by Poles from Russia, Irish Catholics from Britain, Hungarians from Austria, Germans from Denmark in 1830 or 1848 with the southern slave state secession to form the Confederate States of America in 1861
