Shah Mohammad ( ; ; 1780–1862), was a Punjabi poet who lived during the reign of Maharaja Ranjit Singh (1780 – 1839) and is best known for his book Jangnama (Book of War) written around 1846, which depicts the First Anglo-Sikh War (1845 – 1846) that took place after the death of Maharaja Ranjit Singh in 1839. It is widely believed by historians that Shah Mohammad had gathered his book material from many eye-witness accounts of his relatives employed in Maharaja Ranjit Singh's army. That's how he could piece together a complete picture of the battle between the Punjabis and the British. Therefore, Shah Mohammad's book is considered the most accurate book on the reasons for the fall of Sikh rule in the Punjab.
