Vincent van Gogh lived during the Impressionist era. With the development of photography, painters and artists turned to conveying the feeling and ideas behind people, places, and things rather than trying to imitate their physical forms. Impressionist artists did this by emphasizing certain hues, using vigorous brushstrokes, and paying attention to highlighting. Vincent van Gogh implemented this ideology to pursue his goal of depicting his own feelings toward and involvement with his subjects. Van Gogh's portraiture focuses on color and brushstrokes to demonstrate their inner qualities and Van Gogh's own relationship with them. Vincent van Gogh painted portraits throughout his career from 1881 through 1890. The Netherlands and Brussels (1881–1886) Van Gogh was fascinated with making portraits early in his artistic career.

Unlike the character studies, the work was detailed in pencil with watercolor and chalk. At this time it was rare for Van Gogh to use color, as he found it difficult to work with (see early works of Vincent van Gogh). Peasant character studies In November 1882, Van Gogh began drawings of individuals to depict a range of character types from the working class. The "peasant genre" that greatly influenced Van Gogh began in the 1840s with the works of Jean-François Millet, Jules Breton, and others. In 1885, Van Gogh described the painting of peasants as the most essential contribution to modern art. Van Gogh held laborers up to a high standard of how dedicatedly he should approach painting, "One must undertake with confidence, with
