William Blake's Songs of Innocence and Experience includes 'Tyger Tyger' (in the 'Experience' section), which has been reckoned a commentary on the French Revolution. Blake used to wear a red cap to show sympathy for the revolutionary cause, until 'The Terror' started, and he became aware just what a ghastly, bloodthirsty business it was.

One can see how the French republic and Boney would have become romantic rallying points for the Brit commoners, stuck under the yoke of an idle, corrupt, self-interested monarchy, and whose struggles towards self-emancipation eg the Tolpuddle Martyrs had been dealt with cruelly. The fact that Napoleon himself was a tyrant and warmonger would have been conveniently overlooked, just as the modern British left have lionised Castro and Trotsky while refusing to 'fess up to their police state methods.

So, plus ca change, plus la meme chose. Except they arguably got better songs out of it in the old days.
