:::::I'm sure that you, like me, have seen the metal hoops at Liverpool's Albert Docks to which slaves were attached while in transit to the US. But I'm not aware that Manchester had any significant involvement in the slave trade, except as others have already pointed out to try and help stamp it out. In reality I think that Britain has a rather honourable place in the history of slavery, and perhaps the Royal Navy's finest hour was in fighting the slave traders, something that no other nation at that time could have done. People also seem to have a very one-dimensional view of slavery, and think it was all about evil white Europeans capturing black Africans, but nothing could be further from the truth; it was black Africans selling other black Africans into slavery. And it wasn't uncommon for Barbary pirates even to raid English towns and villages for slaves. In short, some of the cotton used in Manchesater's cotton mills may well have been produced by slaves, but so fucking what?
