Edward A. Freeman writes about the comprehensive history of the Norman conquest of England, examining both its long-term causes and its definitive historical results. The work begins with an extensive preliminary history of the English nation, starting from the early Teutonic settlements, the formation of the kingdom of England, and the constitutional developments of the tenth and eleventh centuries. Freeman details the political structures of early England, the evolution of the kingship, the power of the Witenagemót, and the complex relations between the English crown and dependent Celtic kingdoms.
The narrative then shifts to the history of Normandy during the tenth century, detailing the Scandinavian settlements in Gaul under Rolf and the subsequent reigns of William Longsword and Richard the Fearless. The text establishes the parallel histories of England, France, and Normandy to explain the deep-rooted causes that eventually brought the two nations into armed conflict.
A central problem posed in the text is why the Norman Conquest succeeded where earlier Danish invasions resulted in absorption into the English polity. Freeman argues that the conquest was not merely a military victory, but a profound political and social turning point that placed a foreign ruling class over an existing, highly organized English society without entirely erasing its ancient laws and institutions.
The argument develops through meticulous analysis of primary sources, chronicles, and legal documents, contrasting the political sophistication of Anglo-Saxon England with the rising feudal structures of the continent. Freeman covers the main storylines of the Danish conquests under Swegen and Cnut, the reigns of Æthelred and Edward the Confessor, and the ultimate clash at the Battle of Hastings.
The volume concludes by setting the stage for the direct history of the Norman Conquest itself, emphasizing that the event must be understood as an imposition of a new foreign aristocracy upon an enduring native framework rather than the absolute birth of a new nation.
