Interesting point. I didn't know that about the extent that was a British priority in the Congress of Vienna, though I certainly knew the importance of it, like I said it's probably the single most successful thing the British did, moreso than the blockade.Excellent article. One point not mentioned here (which I also wasn't aware of before reading Zamoyski's book on the subject) was just how strident Britain was about getting universal abolition of the slave trade passed at the Congress of Vienna in 1815. One can certainly argue that the best justification of national pride that year was not Waterloo but how Castlereagh, otherwise obviously very conservative, insisted on this to the point that the other representatives thought he was some weirdo with a randomly specific cause (shades of the Blackadder election sketch), especially the Spanish representative, the Marquis of Labrador. It is striking to see the gulf of attitudes described, especially when abolition had been such a controversially-fought issue not so many years before in Britain - and perhaps indicative of how much attitudes had diverged from the continent in the years of the Continental System on this as well as other matters such as fashion.
