What century is the setting for Mark Twain's novel 'The Prince and the Pauper'?

A common theme which has greater implications. Eg the problem allows ID theft to continue, so many are fooled by appearances, they hired uncredited charlatans who learned the right words to say. Fake Dr & nurses, count (esses), claim of lineage & Ponzi investment schemes. Always get credentials, not just hearsay ..

Mark Twain was a fantastic writer!!
