Arthur Weststeijn is assistant professor in political history at Utrecht University. He studies the relationship between politics and intellectual culture, with a specific focus on republicanism and ideas and ideologies of empire. He is specialized in the history of the seventeenth-century Dutch Republic and its colonial empire, the history of Spain and colonial Spanish America, and Italian history and contemporary politics.

His current research concerns the intellectual history of early-modern (Dutch) colonialism, the history of anticolonial thought, and memory cultures in (post)colonial Latin America. With archeologists and classicists in Rome and Groningen, he investigates the connections between ancient and modern forms of settler colonialism. Recently he also participated in collective research projects on the history of slavery in the Dutch empire and the representation of republican statehood in Venice, Genoa, and the Dutch Republic. Earlier he published extensively on early modern republicanism, the political uses of classical heritage, and the making of modern Italy, including the monographs Commercial Republicanism in the Dutch Golden Age (2012), Termini: Cornerstone of Modern Rome (with Frederick Whitling, 2017), and Het Italiaanse experiment (with Pepijn Corduwener, 2020). He has also published Dutch translations of modern Italian philosophy, including work of Antonio Gramsci and Mario Perniola.
