An upcoming exhibition at the New York Public Library’s Schomburg Center for Research in Black Culture will feature a portrait of Maharani Bumba Duleep Singh, the wife of Maharaja Duleep Singh, the last recognized Sikh monarch after the British annexed the Sikh empire in 1849. From wikipedia:

Maharani Bamba Duleep Singh born Bamba Müller (July 6, 1848 – September 18, 1887) was the wife of Maharaja Duleep Singh. Brought up by Christian missionaries, she married Duleep Singh and became Maharani Bamba, wife of the last Maharaja of Lahore.^[1] Her transformation from illegitimate girl living in a Cairo mission to a Maharani living a life of luxury with the “Black Prince of Perthshire” has been compared to the “Cinderella” story.^[1]

The exhibition, called Africans in India: From Slaves to Generals and Rulers, is to run from February 1 through May 18, 2013.
