Ceremonies have been held across Europe and around the world to remember soldiers who have died in the line of duty.
The tradition dates back to 1919, and the first anniversary of the end of World War I – the Armistice was signed on the eleventh hour of the eleventh day of the eleventh month.
In Paris, French President Nicolas Sarkozy laid a wreath at the tomb of the unknown soldier.
It was a day, he said, to remember all those who had died for France, not just in the 1914-18 conflict.
British Defence Minister, Philip Hammond, joined troops in Afghanistan where 341 soldiers have been killed in action in the last decade.
The commemoration in Ypres in Belgium was particularly moving with the traditional poppy parade. The flower, the first to grow on the graves of the hundreds of thousands who fell in the Battle of Flanders, has since become the symbol of their sacrifice.
