This is the long-awaited biography of the great humanist historian of eighteenth-century Ireland. Carlow landlord, writer and political commentator, Lecky achieved fame in his lifetime as the author of monumental works of Irish, English and European history, and saw himself as heir to the great tradition of colonial nationalism vested in Swift, Burke and Grattan. A classic Victorian intellectual, he championed rationalism, loathed bigotry and was an admirer of Daniel O’Connell. In later life he became a ‘revisionist’ of his own earlier work, opposing Parnell and adopting a position of liberal unionism. He represented his alma mater Trinity College, Dublin, from 1895 to his death, campaigning vigorously against Home Rule. This critical account of Lecky’s life, writings and ideals opens up a neglected area of nineteenth-century Irish and continental historiography, and documents the parts he played in the unfolding drama of Anglo-Irish relations and the emergence of Irish nationalism. It makes an invaluable contribution to the history of ideas, and deepens our understanding of the nature of culture and politics in modern Ireland.
