The traditional Roman-centric view confines the Migration Period to between 300 and 700 AD and between the Danube-Rhine frontier and the Atlantic coast of Europe, but in fact, this cataclysm defies both temporal and spatial perimeters. This book attempts to provide a wider view of this phenomenon to include both a broader geographical picture and its precursors and aftermath. It aims to identify the root causes of major migration flows and determine their routes based on recent advances in science - archaeology, genetics and climatology in particular. The book is a continuation to Maelstrom.
