The book was written and published in early Victorian era Britain when it was experiencing a nostalgic interest in its forgotten Christmas traditions, and at the time when new customs such as the Christmas tree and greeting cards were being introduced. Dickens' sources for the tale appear to be many and varied but are principally the humiliating experiences of his childhood, his sympathy for the poor, and various Christmas stories and fairy tales.
The tale has been viewed by critics like T.A. Jackson and Paul Benjamin Davis as an indictment of 19th-century industrial capitalism. It has been credited with restoring the holiday to one of merriment and festivity in Britain and America after a period of sobriety and sombreness. A Christmas Carol remains popular, has never been out of print, and has been adapted to film, stage, opera, and other media.
