atherine de Medici (1519-89), queen of
France, was born in Florence. She was married to Henry, Duc dOrléans,
afterward Henry II of France, but played no great part in French
politics till 1559, when the first of her three sons, who ruled
over France, ascended the throne as Francis II. Opposed to her
she found two parties, the Guises and the ultra-Catholics on one
hand, and the Protestants, on the other. She entered into an
alliance with the Protestants against the Guises, until the
Treaty of Amboise (1563) showed that they had become too strong.
She then entered into an alliance with Spain and the Guise party
for the extirpation of heretics, which resulted in the Massacre
of St. Bartholomew. During the reign of her second son, Charles
IX (1560), and still more during the reign of her third son,
Henry III (1574), she was virtual ruler of France. Consult Sichels
