The book was written at a time when the British were examining and exploring Christmas traditions from the past as well as new customs such as Christmas cards and Christmas trees. Carol singing took a new lease on life during this time. 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. These Christmas Stories in a whimsical kind of masque which the good humour of the season justified, to awaken some loving and forbearing thoughts, never out of season in a Christian land.
