Why was Mary Queen of Scots beheaded?
I assume the question is about Mary Stuart. She was beheaded for high treason, at the time she was accused of participating in a plot to eliminate Queen Elizabeth. Mary was the daughter of Princess Margareth, sister of Henry VIII therefore she had a claim on the english throne. Being a fervorous catholic, she was allied with Philip II of Spain a ruthless enemy of her sister in law Queen Elizabeth mainly because she was a protestant. When Mary was executed Philip II sent a mighty navy to invade England ( This became know as the invincible armada ). Only, it wasn’t so invincible after all.
