historical significance. The opening of the book sets the stage for a detailed exploration of the invasions, describing the historical context in which France faced continuous threats from a foreign people, the Sarrazins. It addresses questions regarding the nature of these invasions, including the composition of the invading forces and their motivations. Reinaud acknowledges the challenges presented by the existing records—eastern and western—and proposes to synthesize various historical accounts to clarify the often-confusing narratives surrounding these invasions. This section establishes a framework that suggests the author will analyze the events chronologically to contribute further knowledge to this complex period of history.
