In the 1920s and 1930s the Imperial War Graves Commission (later the Commonwealth War Graves Commission) organised for memorial tablets to be erected in a number of cathedrals in France and Belgium to commemorate the British Empire's sacrifice in the 1914–18 war.
The tablets, which display the Royal Coat of Arms and those of Australia, Canada, India, Newfoundland, New Zealand and South Africa, was designed by H.P. Cart de Lafontaine and made by Reginald Hallward.
The tablets were located in cathedral towns in which troops had been quartered.

The first to be unveiled was that in Amiens, in 1923.
In 1924 The Prince of Wales unveiled the tablet in Notre Dame, Paris and subsequently others were placed in Orléans, Marseilles, Nancy, Beauvais, Nantes, Bayeux, Boulogne, Béthune, Le Mans, Lille, Cambrai, Meaux, Laon, Reims, Rouen, Senlis, Soissons, St Omer, St Quentin, Noyon and Arras.
In Belgium tablets were placed in Brussels, Malines, Mons, Antwerp and Ypres.

Replicas of the Westminster Abbey tablet, paid for out of public funds, were installed in Hamilton, Ontario and Christ Church, Vancouver.
A further replica, paid for privately, was put in St George's Church, Baghdad and replicas of the Amiens and standard French tablets flank the entrance to the main conference room at the Commission's Head Office.
