During the early 1900s, the world was subjected to depressions, wars, and revolutions, killing millions of people and bringing poverty and oppression to much of the world. Art movements during this period reflected the chaotic world around them and the revolt of artists against the standards and norms of the past. The artists experimented with materials, forms, images, colors, and whatever was available to bring the new and innovative ideas of art to the world. Throughout history, the female form was painted or sculpted as a popular format. In the early 1900s, the radical, new styles of multiple movements portrayed the female in various methods, from bold, brash use of color to exaggerated features, geometric shapes, and minimalistic objects. The sights and scenes of the vast continent of North America created a broad set of images for artists. Science, technology, mechanization, and industry were common themes to depict the workers' isolation, poverty, working conditions, or plight.
