"Mughal Painting reached its zenith during the reign of Jahangir" explain this.

Mughal painting, also known as Indo-Persian painting, is a style of painting that developed in the Mughal Empire in India. The Mughal Empire was founded in 1526 by the Chaghatai Turkic prince Babur, who was a descendant of Timur, the Turco-Mongol conqueror. Babur established the Mughal Empire in India after defeating the Sultan of Delhi, Ibrahim Lodi, in the Battle of Panipat.

Under the reign of Babur's son, Humayun, Mughal painting began to develop and flourish. Humayun brought several Persian artists with him to India, and they introduced the Mughal court to the styles and techniques of Persian painting. These artists also trained local Indian artists in the Mughal style of painting.

During the reign of Humayun's son, Akbar, Mughal painting reached new heights of excellence. Akbar was an avid patron of the arts, and he encouraged the development of Mughal painting by establishing a large atelier of painters at his court. Akbar also commissioned many paintings, and these works were characterized by their finely detailed and realistic style.

Mughal painting reached its zenith, or peak, during the reign of Akbar's son, Jahangir. Jahangir was a passionate collector of paintings, and he also commissioned many paintings himself. The paintings produced during Jahangir's reign are known for their finely detailed and realistic style, as well as their vibrant colors and compositions. Many of the paintings produced during this period depict court scenes, portraits of the royal family, and scenes from daily life.

Overall, Mughal painting developed and progressed significantly under the earlier Mughal rulers, with each ruler contributing to the development and refinement of the style. It reached its peak during the reign of Jahangir, and his reign is often considered the golden age of Mughal painting.
