Brelan
In England, Brelan eventually developed into the game of Brag, also Bragg, where the possibility of bluffing is an important part of the game. It evidently derived from the game of Brelan and later evolved into Bouillotte, which flourished during the French Revolution. Most experts believe that all these earlier card games played an important part in the formation of modern Poker, the most famous representative of a very ancient and always very popular family of games, all of which can be traced even further back to the old French game of Gilet ("Gillet", "Gile" or "Trionfetti"), which may be considered the most ancient European ancestor of Poker.
