When was the first time remembrance day was celebrated?

The first Remembrance Day was celebrated on November 11, 1919, one year after the end of World War I. Originally called Armistice Day, it was established to honor the soldiers who died in the war. The day was marked by a moment of silence at 11 a.m., the time when the armistice took effect in 1918. Over time, it evolved to commemorate all military personnel who have died in service.
