Catherine De Medici – Queen Of France Supported Nostradamus, Was Suspected Of Poisoning And Blamed For Horrible Massacre

Ellen Lloyd - - If you are a Queen or King, you’re expected to set a good example for the rest of the population, something many historical rulers seem to have forgotten about, or simply ignored. On the other hand, ancient Kings and Queens were also expected to deal with problems that gave rise to a serious threat to their nation’s political and religious stability.

This could be especially difficult to accomplish during the reign of Catherine de Medici when religious conflicts were on the rise in Europe.

Catherine de Medici, (1519 – 1589) has been called the most powerful woman in sixteenth-century Europe and some historians say she did not hesitate to exploit her authority as Queen of France. Did Catherine de Medici only do what was necessary when she responded to crisis brought on by the Protestant Reformation, or was she too dominant and added fuel to the escalating religious violence in France?

Was Catherine de Medici guilty of murdering an enemy with poisoned gloves? Why was she blamed for the horrible St. Bartholomew's Day massacre of 1572? Was she ruthless and evil or simply just desperate to keep the Valois monarchy on the throne at all costs? Were the witch accusations against Catherine de Medici pure fantasies or did she practice dark arts?

Catherine de Medici’s Early Years

As the descendant of one of the most powerful Italian families, the House of Medici, it’s no surprise that Catherine should one day become an influential person, but her early years were by no means a dance on roses.

Born on 13 April 1519 in Florence, Italy Catherine was the only child of the daughter of Duke Urbino, Lorenzo II of Medici, and Madeleine de la Tour. Catherine could never enjoy the company of her parents because they both died within a month of her birth.  However, she soon became of interest to the Vatican. Two of Catherine's uncles were popes, Pope Leo and Pope Clement VII.

Pope Leo died when Catherine was only two-year-old, but when Pope Clement VII was elected in 1523, she ended up in the Palazzo Medici Riccardi in Florence. Catherine was important to Pope Clement VII because she could improve the Vatican's contacts with France.

Catherine de Medici Marries King Henry II Who Is In Love With Diane de Poitiers

When Catherine was 14-year-old she became the wife of King Henry II, who was the same age.

Catherine and Henry's marriage was not a love affair, and everyone was aware that the king had many mistresses. During her marriage with King Henry, Catherine had no political influence as queen. Henry’s great love and chief mistress, Diane de Poitiers received the Château of Chenonceau, in the Loire Valley and she was more powerful than Catherine.

Of course, the fact that Catherine did not give birth to any children for the first 10 years of their marriage did not exactly improve the situation. Catherine was under pressure to produce an heir. Finally, in 1544 she gave birth to a son who was given the name Francis.

After conceiving once, it seemed no longer a problem to produce children. Catherine gave birth to 10 children and seven of them survived to adulthood, and three became kings.

However, her ability to give birth did not improve her marriage. King Henry was deeply in love with his beautiful, 20-year older mistress Diane de Poitiers.

Unexpected Death Of Catherine's Husband Henry II

Henry loved tournaments. On 30 June 1559, a tournament was held near Place des Vosges to celebrate the Peace of Cateau-Cambrésis with his longtime enemies, the Habsburgs of Austria, and to celebrate the marriage of his daughter Elisabeth of Valois to King Philip II of Spain.

Henry did not expect such a fatal end of his life. During a jousting match, Henry was fatally wounded in the eye by a fragment of the splintered lance of Gabriel Montgomery, captain of the King's Scottish Guard. During his life's last tournament, the king's lance wore the colors of Diane de Poitiers (1499 - 1566), his long-lived mistress rather than his wife's.

His life couldn't be saved. King Henry died ten years later, on 10 July 1559, at the age of 40.

Catherine de Medici As A King Mother

When King Henry passed away it was time for his 15-year-old son Francis II to ascend the throne.  King Francis II married Maria, the Queen of Scots, but his reign did not last long because he died of an ear infection in 1560.

Eventually, the throne was taken over by his younger brother Charles IX  who ruled as King of France for 14 years. However, King Charles IX was not very long-lived either and died at the age of 24. The next king became Henry III, who was Catherine’s favorite son.

Suspicions Of Murder With Poisoned Gloves

Catherine de Medici and her sons lived in difficult times, marked by the rising of religious tensions between Protestants (Huguenots) and French Catholics. In an attempt to solve their doctrinal differences, Catherine summoned church leaders from both sides, but she was unsuccessful and couldn’t reach an agreement that suited both parties.

The Huguenots, French Protestants who followed the teachings of John Calvin suffered severe persecution for their faith, but they were nevertheless gaining power and support from members of the nobility. The Huguenots retreated to the fortified stronghold of La Rochelle where they were joined by Jeanne d'Albret, the Protestant queen regnant of Navarre, and her son, Henry of Bourbon.

In a letter to the Queen of France, Jeanne d'Albret wrote: “We have come to the determination to die, all of us, rather than abandon our God, and our religion.”

Catherine de Medici declared Jeanne d'Albret, the most shameless woman in the world, but she tried to persuade her to come to the Royal Court, something Jeanne d'Albret refused to do.

However, finally, Jeanne d'Albret agreed and it was decided that her son and Margaret, a daughter of Catherine would marry, but only under the condition that Henry could remain a Huguenot.

When Jeanne arrived in Paris to buy clothes for the wedding, she was taken ill and died on 9 June 1572, aged forty-three. Huguenot writers later accused Catherine of murdering her with poisoned gloves. Still, Catherine de Medici’s guilt has never been proven.

Catherine de Medici Was Blamed For St. Bartholomew's Day Massacre

Catherine de Medici became hated and blamed for the horrible St. Bartholomew's Day Massacre in 1572. The massacre took place just some days after the wedding of Henry III of Navarre and Margaret. The bloody slaughter of the Huguenot happened on the night of 23–24 August.

Who was the initiator of this brutal massacre?  Officially, it was King Charles IX who permitted it, but he did so under the pressure of his Catholic mother.

There are no exact numbers of how many people died, but it’s estimated that between 5,000 – 30,000 were killed in the massacre that lasted several weeks. The St. Bartholomew’s Day massacre also marked a turning point in the French Wars of Religion, the second deadliest religious war in European history that cost about 3 million people their lives.

Catherine de Medici's Support For Nostradamus And Interest In Art And Occult Knowledge

Catherine de Medici shared her family’s great love for art. She was also interested in astronomy, astrology, architecture and there were rumors she was fascinated with occult knowledge.

Since Catherine believed in prophecies, it’s no wonder that she became one of Nostradamus’ greatest supporters and admirers. Catherine de Medici made Nostradamus Counselor and Physician-in-Ordinary to King Henri's court. Nostradamus made many predictions that concerned Catherine de Medici and her family. Some of them turned out to be true and she valued his advice. It is even said that Nostradamus made a talisman for her.

During her reign, Catherine de Medici was also accused of practicing dark arts that she taught her son Henry II. According to rumors, Catherine de Medici showed great interest in the occult. Her acquaintance with Cosimo Ruggeri, an Italian astrologer was one of the reasons why the Queen of France was suspected of dealing with dark, evil powers. Catherine gave patronage to the Ruggeri brothers and Cosimo was believed to be Catherine's own "trusted necromancer, and specialist in the dark arts". During his lifetime, Cosimo Ruggeri became well-known as a master of the occult, black magic, and witchcraft.

During the Renaissance the distinction between 'magician' and 'witch' was unclear and many queens and ordinary women were accused of witchcraft. There are very few historical documents that could shed light on the truthfulness of these rumors, though.

What we do know with certainty is that Catherine de Medici died on 5 January 1569, aged 69. She was always a strong-willed woman and without her, it’s unlikely that her sons would have remained in power.
