Impressionism was a 19th-century art movement that began as a loose association of Paris-based artists whose independent exhibitions brought them to prominence in the 1870s and 1880s. The name of the movement is derived from the title of a Claude Monet work, Impression, Sunrise (Impression, soleil levant), which provoked the critic Louis Leroy to coin the term in a satiric review published in Le Charivari.
Impressionism also describes art created in this style, but outside of the late 19th century time period.
Radicals in their time, early Impressionists broke the rules of academic painting. They began by giving colours, freely brushed, primacy over line, drawing inspiration from the work of painters such as Eugène Delacroix. They also took the act of painting out of the studio and into the modern world. Previously, still lifes and portraits as well as landscapes had usually been painted indoors. The Impressionists found that they could capture the momentary and transient effects of sunlight by painting en plein air. Painting realistic scenes of modern life, they portrayed overall visual effects instead of details. They used short "broken" brush strokes of mixed and pure unmixed colour, not smoothly blended or shaded, as was customary, in order to achieve the effect of intense colour vibration.
The public, at first hostile, gradually came to believe that the Impressionists had captured a fresh and original vision, even if it did not receive the approval of the art critics and establishment.
In an atmosphere of change as Emperor Napoleon III rebuilt Paris and waged war, the Académie des Beaux-Arts dominated the French art scene in the middle of the 19th century. The Académie was the upholder of traditional standards for French painting, both in content and style. Historical subjects, religious themes, and portraits were valued (landscape and still life were not), and the Académie preferred carefully finished images which mirrored reality when examined closely. Colour was somber and conservative, and the traces of brush strokes were suppressed, concealing the artist's personality, emotions, and working techniques.
The Académie held an annual, juried art show, the Salon de Paris, and artists whose work displayed in the show won prizes, garnered commissions, and enhanced their prestige. The standards of the juries reflected the values of the Académie, represented by the highly polished works of such artists as Jean-Léon Gérôme and Alexandre Cabanel. Some younger artists painted in a lighter and brighter manner than painters of the preceding generation, extending further the realism of Gustave Courbet and the Barbizon school. They were more interested in painting landscape and contemporary life than in recreating scenes from history. Each year, they submitted their art to the Salon, only to see the juries reject their best efforts in favour of trivial works by artists working in the approved style. A core group of young realists, Claude Monet, Pierre-Auguste Renoir, Alfred Sisley, and Frédéric Bazille, who had studied under Charles Gleyre, became friends and often painted together. They soon were joined by Camille Pissarro, Paul Cézanne, and Armand Guillaumin.
