She is certainly up there with Jezebel and Theodora.
Imelda comes to mind, as well.
The beginning of “protection racket” governance at least at the national level began with the Clintonistas and continues under Obama. Microsoft big wig Bill Gates was not particularly political till Janet Reno sued him for billions. He learned his lesson and now pays his “protection” and gives “respect” to Godfather.
And María Estela Martínez Cartas de Perón............
Catherine de’ Medici served as regent for her three sons when they held the French throne.
Catherine de Medici has been held partly responsible for starting the French Wars of Religion. When Henry II of France died, she was thrust into being Regent for Francis II, a weak, sickly, and indecisive boy. When Francis was married off to Mary Stuart (Mary, Queen of Scots), this further undermined Catherine’s influence at court.
The nobility, which had been contained under Francis I and Henry II, sensed an opportunity. As a counter move, Catherine booted the Guise family out of the royal court, overall not a good political move, as the Guise family were strongly Catholic, as some 90% of France was then Catholic. Anthony of Bourbon was appointed as Lieutenant-General of France, representing the Calvinist Huguenots, which set the stage for the Wars of Religion, a series of conflicts which ended in the Huguenots being largely evicted from France.
There is a lot more to the story, but you see the effects of somebody getting in WAY over her head.
Don’t forget Semiramis.
