John Dudley, Duke of Northumberland is an enigmatic character in Tudor history. He makes his appearance during the last days of King Henry VIII and came to great prominence during the reign of King Edward VI. He was largely responsible for the execution of Protector Edward Seymour, Duke of Somerset and for the short reign of Lady Jane Grey.

Christine Hartweg has a fascination for Robert Dudley, Earl of Leicester, the great favorite of Queen Elizabeth I. By extension, she has done meticulous research into Leicester’s father resulting in this biography. There is great detail here on the personal life of John Dudley including his early life and the execution of his father after the death of King Henry VII. It is interesting to note he had a devoted relationship with his wife, Jane Guildford. Her father had been Northumberland’s mentor and the couple had a large and loving family.

Hartweg recounts Northumberland’s rise to power including his clashes with the Duke of Somerset and his close mentoring of King Edward VI. Northumberland was a great proponent of the Protestant religion. This led him to influence King Edward to modify his will and name his cousin Lady Jane Grey as his successor. Northumberland arranged a marriage between Jane Grey and his son Guildford. It is uncertain if he forged this match specifically so his son could be king and he could retain some of his power. This is an intriguing question.

Another intriguing question is whether Northumberland genuinely repudiated his Protestant faith and became a true Catholic. Or was he just trying to save his own skin? The truth is we will never really know. It is clear that Queen Mary I didn’t believe him and Northumberland was unable to avoid execution. There are no definitive answers to these questions but Hartweg does a great job with the historical evidence and gives us all the possibilities. This book is highly recommended for those interested in the career of John Dudley.
