Let alone James VI & I at the age of 19 when his Mom, whom had been imprisoned under house arrest, since he was a 1 year old, had her head lopped off on order of her virgin 1st cousin, the financer of Shakespeare.
This cousin whom of barren womb, didn't have any kids, so ole Jimmy succeeded her onto the throne, effectively following the Protestant Queen that had ordered his own catholic mother's execution. Keeping constitutional Monarchy in the family.
