The Importance of French Impressionism
There are lots of "isms" in the art world, and Impressionism is one of the more important art movements in regard to the influence it has had on other forms of art since it's inception.
"Impressionism is a 19th-century art movement that originated with a group of Paris-based artists. Their independent exhibitions brought them to prominence during the 1870s and 1880s, in spite of harsh opposition from the conventional art community in France. The name of the style derives from the title of a Claude Monet work, Impression, soleil levant (Impression, Sunrise), which provoked the critic Louis Leroy to coin the term in a satirical review published in the Parisian newspaper Le Charivari." - Wilipedia
