The earliest known use of the term “Merry Christmas,” dates back to 1535 when Bishop John Fisher used it in a letter to Thomas Cromwell, King Henry VIII’s chief minister. Not long after that the English song, “We Wish You a Merry Christmas” was written, and the older term, “Happy Christmas,” was all but forgotten, except by the British Royal Family.
