Irish Potatoes and British Politics: Interests, Ideology, Heresthetic and the Repeal of the Corn Laws

The Repeal of the Corn Laws in 1846 remains one of the most fascinating events in the history of political economy. A parliament securely controlled by the party of agriculture, which was the main beneficiary of protection, abolished protection. Explanations have included the hegemony of Manchester School economics; class conflict; the effectiveness of the Anti-Corn Law League; the personality of Sir Robert Peel; and evangelical religion. We aim to see why the standard ideas from political economy (Chicago and/or Virginia) seem to fit our case so poorly. We use the Aydelotte dataset on rollcalls in the Parliament of 1841–7, augmented from primary sources, and the letters and memoranda of the principal actors.
