An art movement is a tendency or style in art with a specific art philosophy or goal, followed by a group of artists during a specific period of time, (usually a few months, years or decades) or, at least, with the heyday of the movement defined within a number of years. Art movements were especially important in modern art, when each consecutive movement was considered a new avant-garde movement. Western art had been, from the Renaissance up to the middle of the 19th century, underpinned by the logic of perspective and an attempt to reproduce an illusion of visible reality (figurative art). By the end of the 19th century many artists felt a need to create a new style which would encompass the fundamental changes taking place in technology, science and philosophy (abstract art).
