While the UK changed the name of Armistice day some 23 years earlier, the U.S. didn't get around to expanding the meaning of the holiday until 1954 when it changed it to Veterans Day to honor all who served, regardless of war or if they made "the last full measure of devotion."
On this day, Armistice Day officially became Remembrance Day as it was the first time it had been celebrated under that name. Many countries, including those not part of the Commonwealth, still hold this day.
Though it was called Armistice Day then, Remembrance Day was first celebrated by King George V in honor of those who fell during the First World War.
Great Britain declares war on Germany. This brings Canada into the war (because of the country’s legal status as a British dominion) and leaves its foreign policy to the whims of the British parliament — 3,300 miles away. Still, Canadians of British descent offer widespread support.
