Source of the video and information about the terrible treatment RL suffered in France during the Vichy rule, simply click here. The game of RL is still waiting for justice. It's time France faced part of its shameful past France's and did the right thing regarding RL.
One error that is found in the source article above is they are not two codes of the game as mentioned, anymore than American Football is a code of the game. The games of RL, RU and AF have commonality of origin but are all administered totally separately, have their own rules and have very unique styles of play.
