a serious famine. Llywelyn denounced the new administration of de Turberville, however he was accused of sedition. Llywelyn the appealed to King Edward II to call off or control his self-interested agent. But Edward ordered Llywelyn to appear before Parliament to face the treason charge. The king stated that if the charges were found true, Llywelyn would be hanged.
