The creeping crisis of confidence in Empire had its roots in the crippling price Britain had paid for its victory over Germany in the First World War… - Niall Ferguson

The rulers of western Africa prior to the European empires were not running some kind of scout camp. They were engaged in the slave trade. They showed zero sign of developing the country's economic resources. Did ultimately benefit from French rule? Yes, it's clear. And the counterfactual idea that somehow the indigenous rulers would have been more successful in economic development doesn't have any credibility at all.

‘Amazing Grace’ is the supreme hymn of Evangelical redemption….It is therefore tempting to imagine John Newton suddenly seeing the light about slavery and turning away from his wicked profession to dedicate himself to God. But the timing of Newton’s conversion is all wrong. In fact, it was after his religious awakening that Newton became the first mate and then the captain of a succession of slave ships, and only much later that he began to question the morality of buying and selling his fellow men and women.

The First World War was at once piteous, in the poet's sense, and 'a pity'. It was something worse than a tragedy, which is ultimately something we are taught by the theatre to regard as unavoidable. It was nothing less than the greatest error of modern history.
