Armand Jean du Plessis, 1st Duke of Richelieu (9 September 1585 – 4 December 1642), commonly known as Cardinal Richelieu, was a French Catholic prelate and statesman who had an outsized influence in civil and religious affairs. He became known as the Red Eminence (French: l'Éminence Rouge), a term derived from the style of Eminence applied to cardinals and their customary red robes.
Consecrated a bishop in 1607, Richelieu was appointed Foreign Secretary in 1616. He continued to rise through the hierarchy of both the Catholic Church and the French government, becoming a cardinal in 1622 and chief minister to King Louis XIII in 1624. He retained that office until his death in 1642, when he was succeeded by Cardinal Jules Mazarin, whose career the cardinal had fostered. Richelieu became engaged in a bitter dispute with Marie de Médici, the king's mother, and formerly his close ally.
Richelieu sought to consolidate royal power and restrained the power of the nobility in order to transform France into a strong centralized state. In foreign policy, his primary objectives were to check the power of the Habsburg dynasty (reigning notably in Spain and Austria) and to ensure French dominance in the Thirty Years' War of 1618–1648 after that conflict engulfed Europe. Despite suppressing the Huguenot rebellions of the 1620s, he supported Protestant states like the Swedish Empire and the Dutch Republic to help him achieve his goals. Although he was a powerful political figure in his own right, events such as the Day of the Dupes (French: Journée des Dupes) in 1630 showed that Richelieu's power still depended on the king's confidence.
An alumnus of the University of Paris and headmaster of the College of Sorbonne, Richelieu renovated and extended the institution. He became famous for his patronage of the arts and founded the Académie Française, the learned society responsible for matters pertaining to the French language. As an advocate for Samuel de Champlain and New France, he founded (1627) the Compagnie des Cent-Associés; he also negotiated the 1632 Treaty of Saint-Germain-en-Laye under which Quebec City returned to French rule after English privateers took it in 1629. He was created Duke of Richelieu in 1629.
Born in Paris on 9 September 1585, Armand du Plessis was the fourth of five children and the last of three sons: he was delicate from childhood and suffered frequent bouts of ill-health throughout his life. His family belonged to the lesser nobility of Poitou: his father, François du Plessis, seigneur de Richelieu, was a soldier and courtier who served as the Grand Provost of France, and his mother, Susanne de La Porte, was the daughter of a famous jurist.
When Richelieu was five years old, his father died of fever in the French Wars of Religion, leaving the family in debt; however, with the aid of royal grants, the family was able to avoid financial difficulties. At age nine, young Richelieu was sent to the College of Navarre in Paris to study philosophy. Thereafter, he began to train for a military career. There, he learned mathematics, fencing, horse riding, dancing skills, courtly manners, and military drill. His private life seems to have been typical for a young officer of the era; in 1605, aged twenty, he was treated by Théodore de Mayerne for gonorrhea.
Henry III had rewarded Richelieu's father for his participation in the Wars of Religion by granting his family the Bishopric of Luçon. The family appropriated most of the revenues of the bishopric for private use; they were, however, challenged by clergymen who desired the funds for ecclesiastical purposes. To protect the important source of revenue, Richelieu's mother proposed to make her second son, Alphonse, the bishop of Luçon. Alphonse, who had no desire to become a bishop, became instead a Carthusian monk. Thus, it became necessary that the younger Richelieu join the clergy. He had strong academic interests and threw himself into studying for his new post.
In 1606, Henry IV nominated Richelieu to become Bishop of Luçon. As Richelieu had not yet reached the canonical minimum age, it was necessary that he journey to Rome for a special dispensation from Pope Paul V. This secured, Richelieu was consecrated bishop in April 1607. Soon after he returned to his diocese in 1608, Richelieu was heralded as a reformer. He became the first bishop in France to implement the institutional reforms prescribed by the Council of Trent between 1545 and 1563.
At about this time, Richelieu became a friend of François Leclerc du Tremblay (better known as "Père Joseph" or "Father Joseph"), a Capuchin friar, who would later become a close confidant. Because of his closeness to Richelieu, and the grey colour of his robes, Father Joseph was nicknamed L'éminence grise (lit. 'the Grey Eminence'). Later, Richelieu often used him as an agent during diplomatic negotiations.
In 1614, the clergymen of Poitou asked Richelieu to be one of their representatives to the Estates-General. There, he was a vigorous advocate of the Catholic Church, arguing that it should be exempt from taxes and that bishops should have more political power. He was the most prominent clergyman to support the adoption of the decrees of the Council of Trent throughout France; the Third Estate (commoners) was his chief opponent in this endeavour. At the end of the assembly, the First Estate (the clergy) chose him to deliver the address enumerating its petitions and decisions. Soon after the dissolution of the Estates-General, Richelieu entered the service of King Louis XIII's wife, Anne of Austria, as her almoner.
Richelieu advanced politically by faithfully serving the queen-mother's favourite, Concino Concini, the most powerful minister in the kingdom. In 1616, Richelieu was made Secretary of State, and was given responsibility for foreign affairs. Like Concini, the Bishop was one of the closest advisors of Louis XIII's mother, Marie de' Medici. The queen had become Regent of France when the nine-year-old Louis ascended the throne; although her son reached the legal age of majority in 1614, she remained the effective ruler of the realm. However, her policies, and those of Concini, proved unpopular with many in France. As a result, both Marie and Concini became the targets of intrigues at court; their most powerful enemy was Charles de Luynes. In April 1617, in a plot arranged by Luynes, Louis XIII ordered that Concini be arrested, and killed should he resist; Concini was consequently assassinated, and Marie de Médici overthrown. His patron having died, Richelieu also lost power; he was dismissed as Secretary of State, and was removed from the court. In 1618, the king, still suspicious of the Bishop of Luçon, banished him to Avignon. There, Richelieu spent most of his time writing; he composed a catechism titled L'Instruction du chrétien.
In 1619, Marie de Médici escaped from her confinement in the Château de Blois, becoming the titular leader of an aristocratic rebellion. The king and the duc de Luynes recalled Richelieu, believing that he would be able to reason with the queen. Richelieu was successful in this endeavour, mediating between her and her son. Complex negotiations bore fruit when the Treaty of Angoulême was ratified; Marie de Médici was given complete freedom, but would remain at peace with the king. The queen-mother was restored to the royal council.
After the death of the king's favourite, the duc de Luynes, in 1621, Richelieu rose to power quickly. The year after, the king nominated Richelieu for a cardinalate, which Pope Gregory XV accordingly granted in September 1622. Crises in France, including a rebellion of the Huguenots, rendered Richelieu a nearly indispensable advisor to the king. After he was appointed to the royal council of ministers on 29 April 1624, he intrigued against the chief minister Charles, duc de La Vieuville. On 12 August of the same year, La Vieuville was arrested on charges of corruption, and Cardinal Richelieu took his place as the king's principal minister the following day, but the Cardinal de la Rochefoucauld nominally remained president of the council (Richelieu was officially appointed president in November 1629).
