Our system of periodization for understanding the market category of free-labour sugar

Historical period	Key features	Corresponding phase in the Arjaliès and Durand (2019) model
Indifference, c. 1600 to 1770s	Per capita sugar consumption rises in Britain. Whether slavery is ethical is a topic that goes undiscussed until the 1760 s when Granville Sharp publishes first anti-slavery pamphlet	“Silencing”/“judgment silence”
1780 to 1790s: attacks on the legitimacy of sugar consumption and appearance of the market category of free-labour sugar	Anti-slavery activists attack the consumption of sugar as an inherently immoral activity. So-called “anti-saccharites” first boycott sugar in 1791 Entrepreneurs in London develop the market category of “free-labour sugar” using raw material imported from India. This sugar becomes the prototype of the market category.	“Turmoil and judgement questioning”
Market category of free-labour sugar is established, 1790s to 1830s	A segment of the British population purchases “free-labour sugar” which is more expensive that slave sugar	“Stability and judgment inclusion” Existence of category with normative attributes
1840s, market category disappearance	Slave-produced sugar floods British market after 1846 tariff changes. No traces of the existence of the market category of free-labour sugar can be found in 1850s and 1860s	Does not correspond to any of the phases in the model developed by Arjaliès and Durand Return to “Silencing”, which we term “(Re)Silencing”
