Established in June 1917 by King George V during the First World War, the MBE honours civilians and servicemen in support roles for their non-combatant contributions to the war effort. The Order comprises five levels; the top two confer knighthood (since 1935, not available to Canadians retaining Canadian citizenship), while the lower three—Commander, Officer, and Member—are available to Canadians. In 1918, it was divided into civil and military divisions and notably included women. The Order can be awarded for gallantry as well as for service. In 1937, the insignia and ribbon colour were changed. There have been 2,726 MBEs awarded to Canadians: 859 civil and 1,867 military.
