As a condition of his ascension to the Throne, Henry “Beauclerk” I (r. 1100 – 1135) issues the Charter of Liberties (a.k.a. the Coronation Charter).  Articles Two and Eight of which prohibit an inheritance tax and makes bribery in the criminal justice system illegal:

• “If any baron or earl of mine shall die, his heirs shall not be forced to purchase their inheritance, but shall retrieve it through force of law and custom.”
• “If any of my barons commit a crime, he shall not bind himself to the crown with a payment as was done in the time of my father and brother, but shall stand for the crime as was custom and law before the time of my father, and make amends as are appropriate.  Anyone guilty of treachery or other heinous crime shall make proper amends.”
