This is an innovative new history of famine relief and humanitarianism. The authors apply a moral economy approach to shed new light on the forces and ideas that motivated and shaped humanitarian aid during the Great Irish Famine, the famine of 1921-1922 in Soviet Russia and the Ukraine, and the 1980s Ethiopian famine. They place these episodes within a distinctive periodisation of humanitarianism which emphasises the correlations with politico-economic regimes: the time of elitist laissez-faire liberalism in the nineteenth century as one of ad hoc humanitarianism; that of Taylorism and mass society from c.1900-1970 as one of organised humanitarianism; and the blend of individualised post-material lifestyles and neoliberal public management since 1970 as one of expressive humanitarianism.
