The Industrial Revolution was a pivotal time in history that changed not only the way people lived, but the way artists perceived the world. Modern Art was their response to this change. There isn't one separate movement from the late 19th century until the advent of Pop Art in the 1960s, which marked the beginning of Contemporary Art, but several major groups formed parts of what we now call Modern Art. Beginning with Impressionism, artists such as Claude Monet, Pierre Auguste Renoir, and Edgar Degas pushed beyond the bounds that restricted art to idealized, commissioned portraits and religious or mythological themes into an impression of the artist's perceptions. Though initially not well received, these artists achieved an important breakthrough, and art lovers today can purchase modern art prints that reflect their work.
