The Labour leader told an audience of young supporters that he would like to see the national curriculum re-written to take into account the damaging impacts of British imperialism such as the slave trade.
Imperialism is usually thought of as the exercise of state power, yes? And the impact of British or even English state power upon slavery and the slave trade was to abolish it.
The slave trade most certainly existed before that, done by Brits and English and others as well. But it wasn’t exactly the state exercising its powers to do so really.
The attempt to do that was the South Sea Company which didn’t work out all that well.
Note what I’m saying here: not that slavery was good nor even the truth that everyone at the time was doing it as just about everyone had been doing it since whenever. Rather, just taking Corbyn at his word. We want to discuss the influence of the state upon slavery. Which was pretty good.
