## History of the Jack Card

The Jack card was originally called the Knave in English history.

The Knave represented a courtier or person who was present at the royal court as a servant.  This is why in a deck of cards, the Jack is below the King and Queen in rank and order, and also why the Jack is dressed in royal clothes.

When the playing cards changed to show the pips and numbers at the corners of the cards, it was confusing since the ‘K’ which represented the King was very close to the ‘Kn’ which represented the Knave.

So Knave was changed to Jack.  The word jack was a word used to refer to a man.  But this word Jack stuck and that is what we call the card to this day.  Another word you may see used for Jack is also Bower.
