Arte Povera (; literally poor art) is a modern art movement. The Arte Povera movement took place between the end of the 1960s and the beginning of the 1970s in major cities throughout Italy: Turin, Milan, Rome, Genoa, Venice, Naples and Bologna. The term was coined by Italian art critic Germano Celant and introduced in Italy during the period of upheaval at the end of the 1960s, when artists were taking a radical stance. Artists began attacking the values of established institutions of government, industry, and culture.
The exhibition "Im Spazio" (The Space of Thoughts), curated by Celant and held at the Galleria La Bertesca in Genoa, Italy, from September through October 1967, is often considered to be the official starting point of Arte Povera. Celant, who became one of Arte Povera's major proponents, organized two exhibitions in 1967 and 1968, followed by an influential book published by Electa in 1985 called Arte Povera Storie e protagonisti/Arte Povera. Histories and Protagonists, promoting the notion of a revolutionary art, free of convention, the power of structure, and the market place.
Although Celant attempted to encompass the radical elements of the entire international scene, the term properly centered on a group of Italian artists who attacked the corporate mentality with an art of unconventional materials and style. Key figures closely associated with the movement are Giovanni Anselmo, Alighiero Boetti, Pier Paolo Calzolari, Luciano Fabro, Jannis Kounellis, Mario Merz, Marisa Merz, Giulio Paolini, Pino Pascali, Giuseppe Penone, Michelangelo Pistoletto, Emilio Prini, and Gilberto Zorio. They often used found objects in their works. Other early exponents of radical change in the visual arts include proto Arte Povera artists: Antoni Tàpies and the Dau al Set movement, Alberto Burri, Piero Manzoni, and Lucio Fontana and Spatialism.
The most diverse public collection of works from the Arte Povera movement is at the Kunstmuseum Liechtenstein.
