Muin-ul-Mulk, known as Mir Mannu, was the son of the Mughal wazir Qamar-ud-din Khan. He commanded at the battle of Manupur in 1748, where the Mughals defeated Ahmad Shah Abdali's first invasion, and was rewarded with the governorship of Lahore.
In the following years he submitted to Abdali and ruled as his governor. He carried out the harshest persecution of the Sikhs in the eighteenth century, sending columns to hunt them in the forests and paying for Sikh heads. Sikh women and children were imprisoned in Lahore and forced to grind heavy millstones while their infants were cut to pieces before them; the women's endurance is recalled in the Ardas.
The Sikhs had a saying: 'Mannu is our sickle, we are his grass; the more he cuts, the more we grow.' He died in 1753 after a fall from his horse.
