What art movement does Mondrian belong to?

Piet Mondrian is associated with the De Stijl art movement, which emerged in the early 20th century in the Netherlands. This movement is characterized by a focus on abstraction, simplicity, and a reduction of forms to geometric shapes and primary colors. Mondrian's work emphasized the use of straight lines and a grid structure, aiming to express a universal aesthetic through balance and harmony. His most famous style is known as "neoplasticism," which embodies these principles.
