Joan of France (1556)
Joan of France (born and died 24 June 1556) was the twin sister of Victoria of France and the last child born to King Henry II of France and his wife, Catherine de' Medici.
Catherine's confinement for this birth came on 24 June 1556.
Joan did not survive and lay dead in her mother's womb for several hours.
Eventually, her arm had to be broken to extricate her.
Her sister Victoria survived but died a month later.
Because the twins' birth nearly cost their mother her life, the king's physician advised the king that there should be no more children; therefore, the king stopped visiting his wife's bedroom and spent all his time with his longtime mistress, Diane de Poitiers.

Joan of Valois, Countess of Beaumont
Joan of Valois (1304–1363) was the daughter of Charles of Valois and his second wife Catherine I of Courtenay, titular empress of Constantinople.
Half sister to Philip VI of Valois, in around 1320 she married Robert III of Artois, Count of Beaumont-le-Roger and seigneur of Conches.
They had five known children:
Robert III of Artois had attempted to recover the title of count of Artois, which had been taken from him by his aunt Mahaut of Artois, but was condemned and exiled in 1331 for making and presenting forged documents in the process of filing against her.
Joan of Valois and their children were therefore imprisoned by order of her half-brother Philip VI.
Catherine de' Medici
Catherine de' Medici (13 April 1519 – 5 January 1589), was an Italian noblewoman who was queen consort of France from 1547 until 1559, by marriage to King Henry II, and Queen mother of kings Francis II, Charles IX and Henry III from 1559 to 1589.
The years during which her sons reigned have been called "the age of Catherine de' Medici" as she had extensive, if at times varying, influence in the political life of France.
She was born in Florence to Lorenzo de’ Medici, Duke of Urbino and Madeleine de La Tour d'Auvergne.
In 1533, at the age of fourteen, Catherine married Henry, second son of King Francis I and Queen Claude of France.
Catherine's marriage was arranged by her uncle Pope Clement VII.
Henry excluded Catherine from participating in state affairs and instead showered favors on his chief mistress, Diane de Poitiers, who wielded much influence over him.
Henry's death thrust Catherine into the political arena as mother of the frail 15-year-old King Francis II.
When he died in 1560, she became regent on behalf of her 10-year-old son King Charles IX and was granted sweeping powers.
From 1560 to 1563, she ruled France as regent for her son Charles IX, King of France.
After Charles died in 1574, Catherine played a key role in the reign of her third son, Henry III.
He dispensed with her advice only in the last months of her life (he would outlive her by seven months).
Catherine's three sons reigned in an age of almost constant civil and religious war in France.
The problems facing the monarchy were complex and daunting but Catherine was able to keep the monarchy and the state institutions functioning even at a minimum level.
At first, Catherine compromised and made concessions to the rebelling Calvinist Protestants, or Huguenots, as they became known.
She failed, however, to grasp the theological issues that drove their movement.
Later she resorted, in frustration and anger, to hard-line policies against them.
In return, she came to be blamed for the excessive persecutions carried out under her sons' rule, in particular for the St. Bartholomew's Day massacre of 1572, in which thousands of Huguenots were killed in Paris and throughout France.
Some historians have excused Catherine from blame for the worst decisions of the crown, though evidence for her ruthlessness can be found in her letters.
In practice, her authority was always limited by the effects of the civil wars.
Her policies, therefore, may be seen as desperate measures to keep the Valois monarchy on the throne at all costs, and her patronage of the arts as an attempt to glorify a monarchy whose prestige was in steep decline.
Without Catherine, it is unlikely that her sons would have remained in power.
According to Mark Strage, one of her biographers, Catherine was the most powerful woman in 16th-century Europe.
