It is not invented, it is has evolved during human history. The oldest cards ever found in Greece, Crete island at Zakros palace, of Minoan empire. Minoan Empire is at least from 3-4th millenium B.C.! Then we find card games in China, and the French discover a card game in Egypt, simillar to today poker. It did not have the Qween and the Ace. It had three kings. The King, the regent, and the "deputy" King. Then French replace the regent with the Qween. After the French revolution the Ace is added, so that not to be the king the higher card, because of Democracy appearence. Also the different "races" spades, hards, diamonds and clubs have a different value. Then this game goes to America and become poker with the simplest rules we know, without the races values!
