Event- Execution of Thomas Seymour

Year- 1549

Location- Tower Hill, London

Thomas Seymour was executed on Tower Hill in London for high treason on 33 different counts. He was already being watched as he was considered untrustworthy and was openly envious of his brother, the Protector Somerset.

In January 1549 it was alleged that Seymour intended to kidnap his nephew, the young king Edward VI. On 16 January 1549 Seymour broke into the king’s apartments at Hampton Court and shot the king’s spaniel after it barked at him. It has also been suggested that Seymour wrote letters to Princesses Mary and Elizabeth encouraging them to rise up against his brother, the Protector.

The warrant was delayed in its signing, as both Protector Somerset (Seymour’s brother) and King Edward VI (Seymour’s uncle) were reluctant to sign it. Many people couldn’t believe the cruelty of Somerset and the King in signing the death warrant of a man of their own blood.

Possibly the most famous line on Seymour’s death was that uttered by Princess Elizabeth (later Elizabeth I): “this day died a man of much wit and very little judgement”. This wasn’t an exaggeration as Seymour had a way with words from all sources, and wrote poetry, but he doesn’t seem to have understood government, which is possibly why Henry VIII didn’t include him in the regency council for his son.
