Barbizon School in the context of "Trees and Undergrowth (Van Gogh series)"

The Barbizon school (French: école de Barbizon, pronounced [ekɔl də baʁbizɔ̃]) is the name given to oil painters and others who were part of an art movement advancing Realism in art, which arose in the context of the dominant Romantic Movement of the time. Roughly active from 1830 through 1870, the "school" gained its name from the village of Barbizon, France, on the edge of the Forest of Fontainebleau, where many of the artists gathered. Most of their works were landscape painting, which occasionally included farmworkers, and genre scenes of village life. Some of the most prominent features of this school are its tonal qualities, color, loose brushwork, and softness of form.

The leaders of the Barbizon school were: Théodore Rousseau, Charles-François Daubigny, Jules Dupré, Edouard Manet, Edgar Degas, Constant Troyon, Charles Jacque, and Narcisse Virgilio Díaz. Jean-François Millet lived in Barbizon from 1849, but his interest in figures with a landscape backdrop sets him rather apart from the others. Jean-Baptiste-Camille Corot was the earliest on the scene, first painting in the forest in 1829, but British art historian Harold Osborne suggested that "his work has a poetic and literary quality which sets him somewhat apart". Other artists associated with the school, often pupils of the main group, include: Henri Harpignies, Albert Charpin, François-Louis Français, and Émile van Marcke.
