Paton looks at an ignored aspect of emancipation. Not in the US, as an American reader might first expect. But in Jamaica, where it occurred in 1838. Unlike the US, there was no uprising by slave owners. An immediate contrast. However, what then ensues has been largely forgotten, relegated to obscure records that Paton dug up. She describes how the legal system then evolved, in order to control the newly freed slaves. The system was dominated by the white educated elite. Machinations then arose, whose net effect was to hold down any unrest. Now described in terms of law and order, with no overt evocation of slavery or serfdom.
I read this from an unusual angle. The science fiction author S M Stirling described an alternate history, where South African whites in the 19th century obtained effective independence from British rule. But were forced to abandon the direct use of slavery. Stirling's story describes how they changed to the use of serfs, slaves in all but name. Reading Paton's narrative of Jamaica suggests in detail how this might have been done.
