Marietta studied law, history, religion and politics at the universities of Utrecht, Yale and Cambridge. Her book Constitutional Intolerance: The Fashioning of the Other in Europe’s Constitutional Repertoires (CUP 2025) explores the impact of right-wing movements on minority protections in France, the Netherlands, Hungary and Poland. Previously, she was at Oxford as postdoctoral research fellow (Blavatnik School of Government/New College) and College Lecturer in Politics at St Peter’s and Lincoln College, teaching History & Politics and PPE. Before taking up the Landecker Lectureship, she was awarded a Leverhulme Early Career Fellowship at the University of Cambridge. At Cambridge, she is affiliated with the Faculty of Divinity, the Department of Politics and International Relations, and Trinity College.
Her project studies the relationship between space, identity and borders in Russia, Hungary and Serbia, and their relationship with territories that are no longer under their control: Ukraine, Transylvania, and Kosovo.
Through the lens of the political imaginaries of the Russian World, Hungarian World, and Holy Serbia, this project will analyse competing conceptions of the sacred underpinning illiberal accounts of democracy and political authority. The project will engage with Eastern as well as Orthodox conceptual discourses on politics and religion to grasp what is at stake with the rise of hybrid authoritarianism in Europe: the assertion of “sacred geographies” beyond one’s own borders, Russia’s growing sphere of influence through its support for far-right movements and spread of disinformation, as well as democratic stability across the European continent.
