Jacques-Louis David (French: [ʒaklwi david]; 30 August 1748 – 29 December 1825) was a French painter in the Neoclassical style, considered to be the preeminent painter of the era. In the 1780s, his cerebral brand of history painting marked a change in taste away from Rococo frivolity toward classical austerity, severity, and heightened feeling, which harmonized with the moral climate of the final years of the Ancien Régime.

David later became an active supporter of the French Revolution and friend of Maximilien Robespierre (1758–1794), and was effectively a dictator of the arts under the French Republic. Imprisoned after Robespierre's fall from power, he aligned himself with yet another political regime upon his release: that of Napoleon, the First Consul of France. At this time he developed his Empire style, notable for its use of warm Venetian colours. After Napoleon's fall from Imperial power and the Bourbon revival, David exiled himself to Brussels, then in the United Kingdom of the Netherlands, where he remained until his death. David had many pupils, making him the strongest influence in French art of the early 19th century, especially academic Salon painting.

Jacques-Louis David was born into a prosperous French family in Paris on 30 August 1748. When he was about nine his father was killed in a duel and his mother left him with his well-off architect uncles. They saw to it that he received an excellent education at the Collège des Quatre-Nations, University of Paris, but he was never a good student—he had a facial tumor that impeded his speech, and he was always preoccupied with drawing. He covered his notebooks with drawings, and he once said, "I was always hiding behind the instructor's chair, drawing for the duration of the class". Soon, he desired to be a painter, but his uncles and mother wanted him to be an architect. He overcame the opposition, and went to learn from François Boucher (1703–1770), the leading painter of the time, who was also a distant relative. Boucher was a Rococo painter, but tastes were changing, and the fashion for Rococo was giving way to a more classical style. Boucher decided that instead of taking over David's tutelage, he would send David to his friend, Joseph-Marie Vien (1716–1809), a painter who embraced the classical reaction to Rococo. There, David attended the Royal Academy, based in what is now the Louvre.

Each year the academy awarded an outstanding student the prestigious Prix de Rome, which funded a 3- to 5-year stay in Rome. Since artists were now revisiting classical styles, the trip provided its winners the opportunity to study the remains of classical antiquity and the works of the Italian Renaissance masters at first hand. Called pensionnaire they were housed in the French Academy's Rome outpost, which from the years 1737 to 1793 was the Palazzo Mancini in the Via del Corso. David made three consecutive attempts to win the annual prize, (with Minerva Fighting Mars, Diana and Apollo Killing Niobe's Children and The Death of Seneca) with each failure allegedly contributing to his lifelong grudge against the institution. After his second loss in 1772, David went on a hunger strike, which lasted two and a half days before the faculty encouraged him to continue painting. Confident he now had the support and backing needed to win the prize, he resumed his studies with great zeal—only to fail to win the Prix de Rome again the following year. Finally, in 1774, David was awarded the Prix de Rome on the strength of his painting of Erasistratus Discovering the Cause of Antiochus' Disease, a subject set by the judges. In October 1775 he made the journey to Italy with his mentor, Joseph-Marie Vien, who had just been appointed director of the French Academy at Rome.

While in Italy, David mostly studied the works of 17th-century masters such as Poussin, Caravaggio, and the Carracci. Although he declared, "the Antique will not seduce me, it lacks animation, it does not move", David filled twelve sketchbooks with drawings that he and his studio used as model books for the rest of his life. He was introduced to the painter Raphael Mengs (1728–1779), who opposed the Rococo tendency to sweeten and trivialize ancient subjects, advocating instead the rigorous study of classical sources and close adherence to ancient models. Mengs' principled, historicizing approach to the representation of classical subjects profoundly influenced David's pre-revolutionary painting, such as The Vestal Virgin, probably from the 1780s. Mengs also introduced David to the theoretical writings on ancient sculpture by Johann Joachim Winckelmann (1717–1768), the German scholar held to be the founder of modern art history. As part of the Prix de Rome, David toured the newly excavated ruins of Pompeii in 1779, which deepened his belief that the persistence of classical culture was an index of its eternal conceptual and formal power. During the trip David also assiduously studied the High Renaissance painters, Raphael making a profound and lasting impression on the young French artist.

Although David's fellow students at the academy found him difficult to get along with, they recognized his genius. David's stay at the French Academy in Rome was extended by a year. In July 1780, he returned to Paris. There, he found people ready to use their influence for him, and he was made an official member of the Royal Academy. He sent the academy two paintings, and both were included in the Salon of 1781, a high honor. He was praised by his famous contemporary painters, but the administration of the Royal Academy was very hostile to this young upstart. After the Salon, the King granted David lodging in the Louvre, an ancient and much desired privilege of great artists. When the contractor of the King's buildings, M. Pécoul, was arranging with David, he asked the artist to marry his daughter, Marguerite Charlotte. This marriage brought him money and eventually four children. David had about 50 of his own pupils and was commissioned by the government to paint "Horace defended by his Father", but he soon decided, "Only in Rome can I paint Romans." His father-in-law provided the money he needed for the trip, and David headed for Rome with his wife, Charlotte, and three of his students, one of whom, Jean-Germain Drouais (1763–1788), was the Prix de Rome winner of that year.

In Rome, David painted his famous Oath of the Horatii, 1784. In this piece, the artist references Enlightenment values while alluding to Rousseau's social contract. The republican ideal of the general became the central focus of the painting with all three sons positioned in compliance with the father. The Oath between the characters can be read as an act of unification of men to the binding of the state. The issue of gender roles also becomes apparent in this piece, as the women in Horatii greatly contrast the group of brothers. David depicts the father with his back to the women, shutting them out of the oath. They also appear to be smaller in scale and physically isolated from the male figures. The masculine virility and discipline displayed by the men's rigid and confident stances is also severely contrasted to the slouching, swooning female softness created in the other half of the composition. Here we see the clear division of male-female attributes that confined the sexes to specific roles under Rousseau's popularized doctrine of "separate spheres".

These revolutionary ideals are also apparent in the Distribution of Eagles. While Oath of the Horatii and The Tennis Court Oath stress the importance of masculine self-sacrifice for one's country and patriotism, the Distribution of Eagles would ask for self-sacrifice for one's Emperor (Napoleon) and the importance of battlefield glory.
