Deep State in 17th century france (from Wikipedia):
The Fronde was a series of civil wars in France between 1648 and 1653, occurring in the midst of the Franco-Spanish War, which had begun in 1635. King Louis XIV confronted the combined opposition of the princes, the nobility, the law courts (parlements), and most of the French people, and yet won out in the end.
Satanism among the political elite in 17th century France:
Catherine Monvoisin, or Montvoisin, née Deshayes, known as "La Voisin" (c. 1640 – February 22, 1680), was a French fortune teller, commissioned poisoner, and professional provider of alleged sorcery. She was the head of a network of fortune tellers in Paris providing poison, aphrodisiacs, abortion, purported magical services and the arranging of black masses, with clients among the aristocracy, and became the central figure in the famous affaire des poisons. Her purported organization of commissioned black magic and poison murder was suspected to have killed anywhere between 1000-2500 people. We've been here before.
Nice post on historical parallels!
