I'm working on an article about fictional engagements with the reign and person of Elizabeth II, who is of course still alive, but I'm curious to know if her illustrious great great grandmother received any such treatment during her similarly lengthy reign. Did she turn up, however briefly, in any of the titanic novels that were one of the chief literary features of her era? Was she "adapted" for the stage?
I'm interested in anything from farce to speculation to the most sober of realistic treatments. -- especially those that attempt, in whatever fashion, to present her as a human being rather than primarily as The Queen.
That's a GREAT question, and I have no answer for you. Would you be interested in fictional works that have a kind of Victoria-ish character, like maybe one that has Britons living under queen Gloriana or something? Not that I know of any offhand, but it's a fascinating subject.
Also, have you tried /r/AskLiteraryStudies ? It's not the busiest sub, but they might be able to help.
Kipling put her into at least one poem. "The Widow at Windsor"
’AVE you ’eard o’ the Widow at Windsor With a hairy gold crown on ’er ’ead? She ’as ships on the foam—she ’as millions at ’ome, An’ she pays us poor beggars in red.
Not sure if it is quite what you are after, however I was watching a documentary on Victoria and it was suggested that the Red Queen in Alice in Wonderland is based off Victoria. I don't have any other sources, the documentary was in Australia called Victoria's Children on SBS
Your question interested me enough to do some research of my own, and while there seem to have been many fictionalised representations of her, for literal representations I could only find George Reynolds' Mysteries of London (a penny dreadful serial).
However, I found some interesting comments on the former type in The Victorian Gothic by Andrew Smith, Remaking Queen Victoria ed. Margaret Homans and Adrienne Munich, Royal Representations by Homans, and Royalties by Gail Turley Houston. Particularly interesting (to me) was Victoria's own adaptation of Maria Edgeworth's Harry and Lucy, writing her own alter-ego in as the main character.
