Molse School, translated as "School of Mol", is a common term for some international paint artists or a specific genre of paintings in late 19th and early 20th century. The paintings typically show picturesque and rustic places, farms, ... of the Belgian municipality Mol, which is located in the Campine. The most famous painters of the Molse School were Jakob Smits and Dirk Baksteen who lived in Achterbos, a hamlet of Mol.
Based upon the Barbizon school the municipality Mol organized an international art exhibition in 1907 and invited painters from all over the world. Most of these artists had not met before and their only connection was their stay in a local hotel during the exhibition. These artists were not tied by a fine art society, neither was there a common style. In total 68 artists participated at this event, showing 212 works. This exhibition was also an attempt to show the artists the beauty of Mol, its heath, the white sand flats and how the inhabitants (mostly farmers) lived. This attempt succeeded.
Upon their return home, the artists showed their paintings to their colleagues. This resulted in those colleagues also coming over to Mol making painting en plein air popular.
