In The Overseer State: Slavery, Indenture and Governance in the British Empire, 1812-1916, Sascha Auerbach revises the history of colonial labor in the British Empire in the nineteenth century, tracing the development of a broad system of regulation that he calls "the overseer state," which spilled over after emancipation from former plantation colonies worked by enslaved laborers to a much wider network of extractive colonies, from South Africa to the Straits Settlements.Before emancipation, most labor regulation in plantation colonies in the Caribbean and the Indian Ocean devolved to private individuals.Most colonies gave slaveholders the greatest possible personal control over the people whom they claimed to own, and a maximum legal flexibility in civil disputes involving enslaved people.Moreover, until Britain acquired a group of new Crown Colonies, subject to more direct rule from London, during and after the Napoleonic Wars, most colonial legislatures were subject to very little central oversight.However, after the wars, and especially as free trade and free labor became keystones of British imperial policy, plantation agriculture and more intensive mining expanded in an empire turning from mass enslavement to the exploitation of wage laborers.Auerbach shows how emancipation and the era of "apprenticeship" that followed framed a much more centralized and public system of imperial labor regulation, further elaborated in the subsequent era of mass indenture; a geography of legally "free" but highly coerced labor.The book is organized chronologically, beginning with the acquisition of new Crown Colonies by the British Empire during the wars with France.Auerbach follows the construction of the Overseer State from before emancipation, when new legal instruments were imposed on Crown Colonies like Trinidad and British Guiana to "ameliorate" the conditions of enslaved labor to prepare the ground for a gradual emancipation.After emancipation, Auerbach emphasizes,
