Remembrance Day is a memorial day observed in Commonwealth countries to remember the members of their armed forces who have died in the line of duty since World War I. This day, or alternative dates, are also recognized as special days for war remembrances in many non-Commonwealth countries.
The day was specifically dedicated by King George V on 7 November 1919 as a day of remembrance of members of the armed forces who were killed during World War I. This was possibly done upon the suggestion of Edward George Honey to Wellesley Tudor Pole, who established two ceremonial periods of remembrance based on events in 1917.
The red remembrance poppy has become a familiar emblem of Remembrance Day due to the poem "In Flanders Fields". These poppies bloomed across some of the worst battlefields of Flanders in World War I, their brilliant red colour an appropriate symbol for the blood spilled in the war.

*****************************
In Flanders fields the poppies blow
Between the crosses, row on row,
That mark our place; and in the sky
The larks, still bravely singing, fly
Scarce heard amid the guns below.
We are the Dead. Short days ago
We lived, felt dawn, saw sunset glow,
Loved and were loved, and now we lie,
In Flanders fields.
Take up our quarrel with the foe:
To you from failing hands we throw
The torch; be yours to hold it high.
If ye break faith with us who die
We shall not sleep, though poppies grow
In Flanders fields.
