Mary, Queen of Scots: Trial and Execution for Treason

The Trial

Yes, Mary was tried for treason in England, October 1586, at Fotheringhay Castle, Northamptonshire. A special commission of 36 nobles and bishops presided—effectively a tribunal, not a jury of peers.

Charges

• Conspiring to assassinate Queen Elizabeth I
• Seeking foreign invasion (Spain, France, Papacy) to depose Elizabeth
• Corresponding with Anthony Babington and others in the Babington Plot (1586)

Legal Controversies

• Sovereign immunity: Mary claimed as anointed queen, not subject to English law.
• Jurisdiction: Tried under English statute (Act of Association 1584) for plots against Elizabeth.
• Evidence: Walsingham's decrypts of coded letters (Babington correspondence)—Mary's secretaries tortured.
• Defense: Denied authorship; claimed entrapment; demanded audience with Elizabeth (denied).

Outcome

• Verdict: Guilty (October 25, 1586)
• Sentence: Death by beheading
• Elizabeth's hesitation: Signed warrant February 1, 1587; claimed she didn't authorize dispatch.
• Execution: February 8, 1587, Great Hall, Fotheringhay. Age 44. 19 years imprisoned in England.

Historical Impact

Removed Catholic claimant to English throne. Provided casus belli for Spanish Armada (1588). Cemented Elizabeth's security but haunted her reign. Mary's son, James VI/I, succeeded Elizabeth (1603)—uniting crowns.
