19th century landscape oil painting in a 9.5×11 frame

The 20th century was a vibrant period for landscape painting, marked by various movements and styles that reflected the changing world. Here are some notable trends and artists associated with original oil landscape paintings from that era:

1. **Impressionism**: Although it began in the late 19th century, Impressionism continued to influence landscape painting into the 20th century. Artists like Claude Monet and Pierre-Auguste Renoir focused on capturing light and atmosphere in their landscapes.

2. **Post-Impressionism**: Artists like Vincent van Gogh and Paul Cézanne explored color and form in new ways. Van Gogh's expressive brushwork and bold colors brought emotional depth to his landscapes.

3. **Fauvism**: This movement, led by artists like Henri Matisse and André Derain, emphasized vivid colors and painterly qualities. Their landscapes often featured non-naturalistic colors that conveyed emotion rather than realism.
