There is another anniversary, more significant than any of those posted recently in my opinion, as important as they are for historical study, and one that is not OT – despite the inaugural event in 1518.

As Schroeder reminds us that, in terms of the British parliament, just “one major reform measure dates from this period [the Napoleonic Wars], the abolition of the slave trade in 1807”

I would only say that if you imagine that slavery, its continued existence or its abolition has nothing to do with “our period’, or the enmity of Britain and France – let alone the origins of the Peninsular War, you are sadly mistaken and need to read a little more widely.
