DeStijl

Dutch for The Style, Die Stijl was founded in 1917. The artists most recognized with the movement were the painters Theo van Doesburg, who was also a writer and a critic, and Piet Mondrian, along with the architect Gerrit Reitveld. The movement proposed ultimate simplicity and abstraction through which they could express a Utopian idea of harmony and order.
