The history of poker is something that is still debated to this day, with some saying it was based on an 11th Century Domino game, others claim it can be traced back to a 16th Century Persian game called "As Nas". The closest european ancestor to poker is a french game called "Poque" which gained popularity in the 17th Century. Texas Hold 'em is widely considered the first form of poker created within the US, in the 19th Century. Hold 'em went on to become the most popular poker variant and possibly the most popular card game of all time.
