A microhistorical inquiry into the life of Furcy, a man held in slavery in the French Indian Ocean colony of Île Bourbon (today Réunion), sheds light on shifting French policies and practices regarding race and slavery from the Old Regime to the general emancipation of 1848. The mobility of two enslaved domestic servants, Furcy and his mother Madeleine, who traveled between Bengal, Île Bourbon, Mauritius, and continental France, challenged French and British understandings of who could be legitimately held as slaves. Furcy's tenacious battle to win recognition of his freedom in multiple jurisdictions is a forgotten precursor to many international disputes over the juridical principle of Free Soil in the age of Emancipation.
