Painter Piet Mondrian (1872 - 1944) was a part of what movement?

Piet Mondrian was a part of the Neoplasticism movement because he believed in using abstract forms and primary colors to express a universal harmony and spiritual truth. Neoplasticism, also known as De Stijl, emphasized simplification and geometric abstraction as a way to create a visual language that transcends the material world and reflects the underlying principles of reality. Mondrian's art, characterized by his iconic grid compositions and limited palette of colors, exemplifies the core ideas of Neoplasticism, making him a prominent figure within this artistic movement.
