The history of poker is a matter of some debate. The name of the game likely descended from the French "poque", which descended from the German "pochen" ('to knock'), but it is not clear whether the origins of poker itself lie with the games bearing those names. It closely resembles the Persian game of "as nas", and may have been taught to French settlers in New Orleans by Persian sailors. It is commonly regarded as sharing ancestry with the Renaissance game of "primero" and the French "brelan". The English game "brag" (earlier bragg) clearly descended from "brelan" and incorporated bluffing (though the concept was known in other games by that time). It is quite possible that all of these earlier games influenced the development of poker as it exists now.
