American Impressionism emerged in the late 19th century as artists returned from Europe, blending French techniques with American subjects. This movement celebrated everyday life, capturing fleeting moments of light and color in landscapes, cityscapes, and domestic scenes. Key artists like Mary Cassatt, John Singer Sargent, and Childe Hassam shaped the movement's style. They used bright colors, broken brushstrokes, and plein air techniques to create vibrant, atmospheric works that reflected America's growing prosperity and cultural confidence.
