I took a BA in History (Medieval Programme) at the University of Trieste (Italy) graduating in 2011 with a final mark of 110 cum laude/110. In 2013 I completed a 2-year-long MA in History at the same University, graduating with a final mark of 110 cum laude/110.
I then attended a school held by the Archivio di Stato di Trieste earning a diploma in Archival Science, Palaeography and Diplomatics in June 2014.
Finally, I started my PhD in Leeds (funded by a School of History/IMS Scholarship) in September 2014.

Research interests

My main research interest is the study of the Byzantine political relations with the West, mostly in the 6th-7th and in the 11th-13th centuries. This has been the common theme of both my BA and MA dissertations, and I am now conducting further research on it during my PhD.

My PhD research project

The aim of my project is to look at the role Venice had in Byzantine-Norman political relations from the beginning of the first Norman expedition in the Balkans (1081) to the end of the twelfth century, when first the death of Henry VI (with the subsequent minority of his son Frederick) and then the Fourth Crusade led to a completely different scenario.

Throughout this period the Byzantines often summoned Venice for help against Norman invasions in the Balkans. Furthermore, the Venetians became more and more involved in the economic life of the Eastern Empire thanks to the significant commercial privileges and concessions that they received.

However, this alliance between Venice and the Byzantines did not last throughout all of this period. For a series of political and economic reasons, some tension arose at different times. The worsening of this relationship culminated in open hostility in 1171, when all the Venetians who were in the Byzantine Empire were arrested and had their goods confiscated by the "Romaioi".
In my research I will also try to explain if these periods of hostility can be linked with (or could have caused the start of) better relations between the rulers of Southern Italy and Venice, or between the former and the Byzantines.
