Vincent van Gogh played a crucial role in the Post-Impressionist movement, known for his emotive use of color and bold brushwork. His dynamic paintings, such as "Starry Night" and "Sunflowers," created vivid impressions of his emotional state and the landscapes around him. Van Gogh's unique style emphasized personal expression and the subjective experience of reality, influencing later art movements. Despite battling mental illness throughout his life and achieving limited recognition during his lifetime, his work gained immense acclaim posthumously, making him one of the most celebrated artists in history.
