When it comes to the whole genre of Steampunk, the only true constants are that Steampunk should begin at some point around the beginning of the Reign of Queen Victoria and end around the end of the Boer War, with some form of Georgian Punk taking place until the end of the First World War.
Now, I'm no historical scholar, so those who are feel free to correct me if I am wrong.
But I was under the impression that what is colloquially referred to as the 'Georgian' period in history was largely confined to the 18th century, namely, the 1700's, named for King George III of England. The period following the Victorian era, and up to World War I, I believe, is commonly known as the 'Edwardian' era, named for the English monarchs, King Edward VII and (until he abdicated) King Edward VIII.
At least, that is how I have always seen these periods defined when researching period fashion and art.
That being said, while I personally prefer to adhere to a more Victorian-era interpretation of Steampunk, I find interest and artistry in many divergent interpretations of the genre. I may not admire certain participants' efforts as much as I adore the creations of others; but that doesn't mean that those I feel less affinity for ought not have a right to exist. After all, restrictions upon self-expression? Pah! Forget that nonsense!
