Explanation
1. The question states that the Mughal School of Painting influenced various schools of Indian miniature art and asks which style was *not* affected by it.
2. Mughal painting, with its emphasis on realism, portraiture, and court scenes, significantly influenced regional painting styles from the 16th century onwards.
3. Pahari painting: Developed in the hills of Punjab and Himachal Pradesh. Early phases showed some Mughal influence, especially in portraiture and refinement, though it retained distinct themes (religious, romantic) and styles.
4. Rajasthani painting: Flourished in Rajput courts. While having indigenous roots, it absorbed Mughal elements in terms of technique, detail, and certain themes, leading to variations across different Rajput states (Mewar, Bundi, Kishangarh etc.).
5. Kangra painting: A major school within the Pahari style, known for its lyricism and delicate naturalism. It refined techniques and aesthetics that showed assimilation of Mughal finesse, although its soul remained rooted in local traditions and Vaishnavite themes.
6. Kalighata painting: Originated in the vicinity of the Kalighat temple in Kolkata in the 19th century. It was a folk style, characterized by bold lines, simple forms, and often satirical or contemporary themes, catering to pilgrims and common people. It developed much later than the peak Mughal influence and maintained a distinct folk character, largely separate from the courtly Mughal or other miniature traditions.
7. Therefore, Kalighata painting was the least affected by the Mughal school compared to the courtly schools of Rajasthan and the Pahari region.
