Augustus Hardin Beaumont has been acknowledged as a fleeting but important figure in British working-class radical literature during the reform agitation of the 1830s. Little consideration has been given, however, to Beaumont’s past as a Jamaican planter and defender of slavery. Formerly a slaveholder, magistrate, and member of the Jamaican Assembly, Beaumont fought in the French and Belgian revolutions of 1830 before organising a militia to put down the 1831−2 Jamaican Slave Revolt. Ostracised for proposing a gradual scheme of emancipation, Beaumont moved to Britain and became a radical abolitionist despite benefiting from the £20 million fund established to compensate former slaveowners. Far from aberrant, the apparent contradictions of Beaumont’s political career and literary output were underpinned by his admiration for America, the country of his birth, and the influence of Jeffersonian republicanism. He is, furthermore, illustrative of the broader ambiguity within British radicalism’s response to emancipation in the 1830s, which, although nominally anti-slavery, incorporated apologias for chattel slavery, especially in the United States.
