Maximiliano Etchepare Guerra is currently pursuing a master’s degree in History at the School of Arts and Humanities of the University of Lisbon, where he earned his bachelor's degree in History in 2025. His master's dissertation, supervised by Professor Hermenegildo Fernandes, investigates the deposition of King Sancho II of Portugal and its broader significance within the politics of Latin Christendom. As an undergraduate, he was awarded a scholarship to work in the ARANHIS project under the supervision of Professors Covadonga Valdaliso and Rodrigo Furtado. His main research interests include palaeography, diplomatics, and the political and intellectual history of the thirteenth century. He has recently published a book chapter on the role of Vincentius Hispanus as bishop of Guarda and royal chancellor. Maximiliano was elected to the pedagogical council of the School of Arts and Humanities for the 2026–2028 term. In scientific outreach, he has promoted historiography and historical knowledge by directing and co-directing several social media pages, such as brasil_antigamente and portugal.antigamente.
