Queen Victoria's Maharajah: Duleep Singh 1838-93 by Michael Alexander & Sushila Anand

Dethroned from his kingdom and forced to convert to Christianity, Duleep Singh eventually secured a sprawling estate in East Anglia. He gained renown as an accomplished marksman, as well as favor with Queen Victoria who procured for him the renowned Koh-I-Noor Diamond. His lavish lifestyle and the India Office's stinginess led him to declare a holy war against the British Empire.
