It came out of a proposal by British Prime Minister David Lloyd George at the Paris Peace Conference in 1919, after World War I, as a compromise to French Marshal Ferdinand Foch's insistence for the French-German border to be pushed back to the Rhine.
)[1] Along with Foch, French Prime Minister Georges Clemenceau had demanded for Germany's western border to be fixed at the Rhine.
Clemenceau relented when the Treaty of Guarantee was proposed, but Foch insisted that the French occupation of the Rhineland was crucial to halt future German aggression.
Foch had stated: "If we do not hold the Rhine permanently there is no neutralization, no disarmament, no written clause of any nature, which can prevent Germany from breaking out across it and gaining the upper hand.
Both houses of the British Parliament approved the Treaty of Guarantee in July 1919 under the condition of its ratification by the United States.
