Catherine de' Medici in the context of "St. Bartholomew's Day massacre"

The French Wars of Religion were a series of civil wars between French Catholics and Protestants (called Huguenots) from 1562 to 1598. Between two and four million people died from violence, famine or disease directly caused by the conflict, and it severely damaged the power of the French monarchy. One of its most notorious episodes was the St. Bartholomew's Day massacre in 1572. The fighting ended with a compromise in 1598, when Henry of Navarre, who converted to Catholicism in 1593, was proclaimed King Henry IV of France and issued the Edict of Nantes, which granted substantial rights and freedoms to the Huguenots. However, Catholics continued to disapprove of Protestants and of Henry, and his assassination in 1610 triggered a fresh round of Huguenot rebellions in the 1620s.

Tensions between the two religions had been building since the 1530s, exacerbating existing regional divisions, and quests for power among the nobles. The sudden accidental death of Henry II of France in July 1559 initiated a prolonged struggle for power between his widow Catherine de' Medici and powerful nobles. These included a fervently Catholic faction led by the Guise and Montmorency families, and Protestants headed by the House of Condé and the Navarrese queen, Jeanne d'Albret. Both sides received assistance from external powers, with Spain and Savoy supporting the Catholics, and England and the Dutch Republic backing the Protestants.

The House of Medici (English: /ˈmɛdɪtʃi/ MED-itch-ee, UK also /məˈdiːtʃi/ mə-DEE-chee; Italian: [ˈmɛːditʃi]) was an Italian banking family and political dynasty that first consolidated power in the Republic of Florence under Cosimo de' Medici and his grandson Lorenzo "the Magnificent" during the first half of the 15th century. The family originated in the Mugello region of Tuscany, and prospered gradually in trade until it was able to fund the Medici Bank. This bank was the largest in Europe in the 15th century and facilitated the Medicis' rise to political power in Florence, although they officially remained citizens rather than monarchs until the 16th century.

In 1532, the family acquired the hereditary title Duke of Florence. In 1569, the duchy was elevated to the Grand Duchy of Tuscany after territorial expansion. The Medici ruled the Grand Duchy from its inception under the builder Cosimo I until 1737, with the death of Gian Gastone de' Medici. The Medici produced four popes of the Catholic Church—Pope Leo X (1513–1521), Pope Clement VII (1523–1534), Pope Pius IV (1559–1565) and Pope Leo XI (1605)—and two queens of France—Catherine de' Medici (1547–1559) and Marie de' Medici (1600–1610). The Medici's grand duchy witnessed degrees of economic growth under the early grand dukes, but was bankrupt by the time of Cosimo III de' Medici (r. 1670–1723).

Henry III (French: Henri III, né Alexandre Édouard; Polish: Henryk Walezy; Lithuanian: Henrikas Valua; 19 September 1551 – 2 August 1589) was King of France from 1574 until his assassination in 1589 and, as Henry of Valois, King of Poland and Grand Duke of Lithuania from 1573 to 1575.

As the fourth son of King Henry II of France and Queen Catherine de' Medici, he was not expected to inherit the French throne and thus was a good candidate for the vacant throne of the Polish–Lithuanian Commonwealth, where he was elected monarch in 1573. During his brief rule, he refused to sign the Henrician Articles into law, which would recognise the szlachta's right to freely elect their monarch. The Henrician Articles became, nonetheless, deeply rooted in Poland's politics as all his successors accepted them. Aged 22, Henry abandoned Poland–Lithuania upon inheriting the French throne when his brother, Charles IX, died without issue.

The Tuileries Garden (French: Jardin des Tuileries, IPA: [ʒaʁdɛ̃ de tɥilʁi]) is a public garden between the Louvre and the Place de la Concorde in the 1st arrondissement of Paris, France. Created by Catherine de' Medici as the garden of the Tuileries Palace in 1564, it was opened to the public in 1667 and became a public park after the French Revolution. Since the 19th century, it has been a place for Parisians to celebrate, meet, stroll and relax. During the 2024 Summer Olympics and Paralympics, it was the site of the Olympic and Paralympic cauldron.

French Renaissance literature is, for the purpose of this article, literature written in French (Middle French) from the French invasion of Italy in 1494 to 1600, or roughly the period from the reign of Charles VIII of France to the ascension of Henry IV of France to the throne. The reigns of Francis I (from 1515 to 1547) and his son Henry II (from 1547 to 1559) are generally considered the apex of the French Renaissance. After Henry II's unfortunate death in a joust, the country was ruled by his widow Catherine de' Medici and her sons Francis II, Charles IX and Henry III, and although the Renaissance continued to flourish, the French Wars of Religion between Huguenots and Catholics ravaged the country.

The Tuileries Palace (French: palais des Tuileries, [palɛ de tɥilʁi]) was a palace in Paris which stood on the right bank of the Seine, directly in the west-front of the Louvre Palace. It was the Parisian residence of most French monarchs, from Henri IV to Napoleon III, until it was burned by the Paris Commune in 1871 and demolished in 1883.

Construction began in 1564, originally to serve as a home for Queen Catherine de' Medici, and was gradually extended until it closed off the western end of the courtyard and displayed an immense façade of 266 metres. Since the destruction of the Tuileries, the courtyard has remained open to the west, and the site now overlooks the eastern end of the Tuileries Garden, forming an elevated terrace between the Place du Carrousel and the gardens proper.
