Although modern sculpture and architecture are reckoned to have emerged at the end of the 19th century, the beginnings of modern painting can be located earlier. The date perhaps most commonly identified as marking the birth of modern art is 1863. the year that Édouard Manetshowed his painting Le déjeuner sur l'herbe in the Salon des Refusés in Paris. Earlier dates have also been proposed, among them 1855 (the year Gustave Courbet exhibited The Artist's Studio) and 1784 (the year Jacques-Louis David completed his painting The Oath of the Horatii).In the words of art historian H. Harvard Arnason: "Each of these dates has significance for the development of modern art, but none categorically marks a completely new beginning .... A gradual metamorphosis took place in the course of a hundred years.

The strands of thought that eventually led to modern art can be traced back to the Enlightenment, and even to the 17th century. The important modern art critic Clement Greenberg, for instance, called Immanuel Kant "the first real Modernist" but also drew a distinction: "The Enlightenment criticized from the outside ... . Modernism criticizes from the inside. The French Revolution of 1789 uprooted assumptions and institutions that had for centuries been accepted with little question and accustomed the public to vigorous political and social debate. This gave rise to what art historian Ernst Gombrich called a "self-consciousness that made people select the style of their building as one selects the pattern of a wallpaper."

The pioneers of modern art were Romantics, Realists and Impressionists.By the late 19th century, additional movements which were to be influential in modern art had begun to emerge: post-Impressionism as well as Symbolism.

Influences upon these movements were varied: from exposure to Eastern decorative arts, particularly Japanese printmaking, to the coloristic innovations of Turner and Delacroix, to a search for more realism in the depiction of common life, as found in the work of painters such as Jean-François Millet. The advocates of realism stood against the idealismof the tradition-bound academic art that enjoyed public and official favor. The most successful painters of the day worked either through commissions or through large public exhibitions of their own work. There were official, government-sponsored painters' unions, while governments regularly held public exhibitions of new fine and decorative arts.

The Impressionists argued that people do not see objects but only the light which they reflect, and therefore painters should paint in natural light (en plein air) rather than in studios and should capture the effects of light in their work Impressionist artists formed a group, Société Anonyme Coopérative des Artistes Peintres, Sculpteurs, Graveurs ("Association of Painters, Sculptors, and Engravers") which, despite internal tensions, mounted a series of independent exhibitions. The style was adopted by artists in different nations, in preference to a "national" style. These factors established the view that it was a "movement". These traits—establishment of a working method integral to the art, establishment of a movement or visible active core of support, and international adoption—would be repeated by artistic movements in the Modern period in art.
