Leading historians of the French, Batavian, Helvetic, Cisalpine and Neapolitan revolutions bridge the gap between the historiographies of the so-called ‘Sister’ Republics. They explore political culture as a set of discourses or political practices. Parliamentary practices, the comparability of ‘universal’ political concepts, late-eighteenth century Republicanism, the relationship between press and politics, and the interaction between the Sister Republics and France are studied from a comparative, transnational perspective.
