Louis, Duc de Montpensier (10 June 1513 – 23 September 1582) was the second Duke of Montpensier, a French Prince of the Blood, military commander and governor. He began his military career during the Italian Wars, and in 1557 was captured after the disastrous battle of Saint-Quentin. When his liberty was restored, he found himself courted by the new regime as it sought to steady itself and isolate its opponents in the wake of the Conspiracy of Amboise. At this time Montpensier supported liberalising religious reform, as typified by the Edict of Amboise he was present for the creation of.
The Guise administration granted him a large super-governorship centred on the Duchy of Anjou in 1560, a territory he would govern for the next five years before handing it over to his son in 1565. By 1561, he was becoming increasingly alienated from the crown's religious policy and moved into opposition with Anne de Montmorency and François, Duke of Guise. As France fell into the French Wars of Religion the following year, he fought for the crown, heading out at the head of a flying column after the security of Paris was assured, brutally massacring the Protestants of Angers after having subdued the town. In the peace that followed, he allied himself with the Guise in their vendetta with the Montmorency, supporting them through both legal and extra-legal means. In 1565 his brother died, and he become governor of Dauphiné, relinquishing this governorship too in 1567 to his son.
During the second civil war he again fought for the crown, besting Protestants that sought to join the main force besieging Paris. On the death of Montmorency, he guided the young Anjou in his leadership of the army. In the third civil war, he again defeated a Protestant army of the south trying to link up with the main body. He also committed another massacre at Mussidan. When Martigues died during the siege of Saint-Jean-d'Angély, Montpensier took up his governorship of Brittany.
In 1572, he supported the Massacre of Saint Bartholomew, unsuccessfully trying to incubate it in Nantes while succeeding in Saumur and Angers. During the fifth civil war he fought in the west, reducing the towns of Lusignan and Fontenay before being recalled to Paris. With a favourable peace declared for the Protestants, Ligues rose up in opposition to it, with the support of the Guise. Montpensier had by now tired of the militant Catholicism he had held for the past decades, and through his support behind toleration and peace, arguing unsuccessfully that it was the only policy that would save France in front of the Estates General. His realignment brought him benefits, precedence over the Guise in ceremony. In 1581, he was tasked with leading a mission to England to secure a marriage between Elizabeth I of England and Alençon, he proved too ill however and had to send his son in his stead. In 1582, his son conducted an army into the Netherlands in support of Alençon's kingship there. He died that year. Henri who had agreed to let his son inherit his governorship of Brittany reneged and provided the province to the ultra Mercœur.
Louis was the son of Louis, Prince of La Roche-sur-Yon, and of Louise, first Duchess of Montpensier. By his mother, he was the nephew of Charles, Duke of Bourbon, whose lands were confiscated after his treason. As a member of the House of Bourbon, he was a Prince of the Blood. In 1538, Louis married Jacqueline de Longwy, Countess of Bar-sur-Seine, daughter of John IV de Longwy, Baron of Pagny, and Jeanne of Angoulême, illegitimate half-sister of King Francis I. On the occasion of his marriage, the King of France returned the lands of Gilbert, Count of Montpensier, and the Counties of Forez, Beaujeu and Dombes to his mother. After her death in 1561, he re-married on 4 February 1570, to Catherine de Lorraine, sister of Henry I, Duke of Guise and of Charles of Lorraine, Duke of Mayenne. His first marriage afforded him a dowry of 60,000 livres, his second a dowry of 200,000 livres.

Jeanne of Bourbon (1541–1620), Abbess of Jouarre;
François (1542–1592), Duke of Montpensier
Charlotte of Bourbon (1547–1582), Abbess of Jouarre, married in 1571 to William "the Silent" of Nassau, Prince of Orange

Louis took part in a number of wars against Charles V. He fought again at the Battle of St. Quentin (1557) where his horse was killed under him and he was taken prisoner.
After the abrupt death of Henri II his young son François came to the throne. His government was controlled by the Guise family, who faced opposition from several factions to their ascendency. This opposition coalesced into the Conspiracy of Amboise in which an attempt was made to kidnap the king and kill the Guise brothers. During the crisis the Edict of Amboise was published from the castle, offering amnesty to those convicted of heresy under certain conditions, the first step towards toleration the crown had undertaken.
In the immediate aftermath of the attempt on the castle of Amboise, flying columns were sent out under several military leaders to crush subsidiary uprisings in various towns. Montpensier was sent with troops to restore order in Angers. Successfully besting this challenge, the Guise were conscious that Condé was likely involved, and as instability continued to rock France in the following months, they sought to isolate him from the other Princes of the Blood, his cousins Montpensier and La Roche-sur-Yon. To this end two super-governorships were created for the princes. For Montpensier a governorship centred on Anjou was combined with Touraine, Maine, Perche, Vendômois, Blois and Amboise. His brother meanwhile received a governorship centred on the Duchy of Orléans. To support him in administering this super-governorship, the sieur de Savigny was delegated as lieutenant-general for the territories.
With the premature death of François shortly after Condé's arrest, in December 1560, his brother Charles IX ascended to the throne. While the Guise were no longer central in the new administration, the Bourbon-Montpensiers were courted by Catherine as a key part of her regency government.
In July 1561, Montpensier travelled to Touraine, to oversee the burial of his mother. As he travelled through the territory it became apparent to him that many were openly practicing Protestantism in his territory. In response he had over one hundred Protestants imprisoned at Chinon. In response thousands of Protestants assembled and besieged him in one of his residences, he capitulated and released the Protestants he had imprisoned. He was summoned to court, where he was chastised for his arresting of the Protestants. Frustrated at his inability to command respect in his territories Montpensier requested permission from the court to retire to his estates, as his orders were disobeyed and he was unable to satisfy his clients requests.
Increasingly alienated from the crown by their toleration policy, he associated himself with the rapprochement between François, Duke of Guise and Anne de Montmorency in 1561, joining them in their agreement to protect the Catholic faith from 'heresy'.
In his role as governor he held responsibility over the town of Angers, which rose up in rebellion during the first French War of Religion. Upon overseeing the re-taking of the town Montpensier had many of the towns Protestants murdered. Montpensier counselled the town leaders to exclude Protestants from office to avoid a repeat of the coup. He was pleased with their progress in bringing order back to the town, praising the town authorities for the work they had done in 1564. With the rebel momentum dissipating after July 1562, Montpensier and Jacques d'Albon were sent out at the head of flying columns to consolidate the royal hold of the Loire and Poitou.
