Aethelred `the Unready' (more accurately, `the ill-advised'), has a reputation for idleness and cowardice which Ryan Lavelle sets out to challenge. He shows how even a small change in perspective produces a very different picture of a king who reigned for 38 years. It is true that within a year of his death a foreign, Danish dynasty was established on his throne, but to judge Aethelred's reign merely from its outcome is misleading. Dr Lavelle sets Aethelred's reign in the context of his predecessors' achievement, no less than the creation of the kingdom of England, and shows how Aethelred maintained and built upon his inheritance. In the process, Dr Lavelle demonstrates that Aethelred's England, far from being a backwater, was an integral part of European political and social life. The book is lavishly illustrated and equipped with a useful glossary. While it can be read with profit by undergraduates and others on history courses, the clear and readable style, refreshingly free from jargon, makes the book available to anyone with an interest in history. Dr Lavelle is to be congratulated on having produced an excellent survey, not just of the reign of Aethelred, but also of English, and indeed European history at the turn of the first millenium.
