So, I'd imagine many of us have sung this as a child, perhaps making the actions of marching up and down hills along with it as is dictated in many a playground... but who was the Grand Old Duke of York, and why did he do all this marching?
Firstly, in case you don't know it, here's the rhyme.
In looking into the origins of this rhyme, I was expecting to stumble over a theory or two about who this Duke of York might be, and in truth that much is true - there are quite a few! However, what I also found was a list of variations which seem to be older than the Duke of York version, the oldest of which (according once again to our friend James Halliwell-Phillips) actually spoke of "The King of France with forty thousand men," who "came upon a hill and so came downe againe"This is quoted in the satire "Pigges Coranto, or Newes from the north" which was written in 1640. The song which includes it is labelled "Old Tarlton's Song.Tarlton, from what I can discover, was a "Clown" or comedic writer from the mid-fifteen hundreds although Halliwell-Phillips claims that he didn't actually write some of the tracts he is known for. He was, however, very well esteemed and considered a great wit!
Another version of this rhyme is that which includes the Dutch commander Maurice of Orange. It loosely translates to :
From here on in, the answer seems to come down to speculation. Could it be an early reference to Richard, Duke of York (1411–1460) who died during the war of the roses atop the Bailey of a Motte and Bailey castle with 8000 men? This theory seems unlikely due to the fact that this song was likely not written for another hundred or so years, and the details of the early versions don't match up.
More likely, this rhyme speaks of a battle during the French revolutionary wars. After the French Revolution, war broke out all over Europe with France, under it's revolutionary government. This conflict is perhaps too much to go into here, but suffice to say that during this skirmish, England launched what was to be known as the Flanders campaign. Flanders, in northern France, is well-known for being a very flat country, but with the exception of Cassel, a small town built up on a Hill. The leader of this campaign was Prince Frederick (d. 1827) who was Duke of York at the time, and whose campaign ended in defeat and the humiliation of being recalled to England. In this case then, the term "grand old Duke" could have been satirical or sarcastically spoken, rather than respectfully and with reverence. As stated above, however, this is mere speculation, and this modern version of the rhyme could in fact be one of many Dukes of York.Sources:
