The study analyses the causes of the deposition and beheading of Saint Constantin Brâncoveanu (15 August 1714), based on domestic narrative sources — the chronicles of Radu Popescu, the Anonymous Chronicle, the accounts of Anton-Maria del Chiaro and Dimitrie Cantemir — and the Ottoman documents published by Mihai Maxim, demonstrating that the Cantacuzino family orchestrated the voivode’s downfall through intrigues, forgeries and denunciations, with the aim of seizing the rule of Wallachia.
