Maharani Chand Kaur
Widow of Kharak Singh and the only woman to rule the Sikh Empire, as regent for two months in 1840–41 before Sher Singh took Lahore.
Chand Kaur was born in 1802 at Fatehgarh, daughter of Jaimal Singh Kanhaiya, and married Kharak Singh. After the deaths of her husband and her son Nau Nihal Singh in November 1840, she claimed the throne.
She was proclaimed regent and Malika Muqaddasa, 'Queen Immaculate', with the support of the Sandhawalia chiefs, and ruled the Sikh Empire for about two months, the only woman to do so. But the army and the Dogra minister Dhian Singh favoured Sher Singh, another son of Ranjit Singh. In January 1841 Sher Singh besieged Lahore Fort, and she gave up her claim.
In June 1842 she was beaten to death by her own servants in the fort, allegedly on the orders of Sher Singh or the Dogras.
