Where was the card game poker invented?

The history of poker is a matter of debate. It closely resembles the Persian game of as nas, and may have been taught to French settlers in New Orleans by Persian sailors. The name of the game likely descended from the French poque, which descended from the German pochen ('to knock'). Yet it is not clear whether the origins of poker itself lie with the games bearing those names. 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.
