István Bölsei Buday, the former deputy of Bihar, joined Ferenc Rákóczi II immediately after the outbreak of Rákóczi’s War of Independence. The nearly 50-year-old man supported the future prince according to his best talent, and his wife, Erzsébet Melczer, also helped him in this. The research conducted in connection with Rákóczi’s War of Independence focuses more on questions of military, economic and social history. Micro-historical explorations have received more emphasis in recent decades, concentrating on groups and individuals who fell outside the scope of traditional research models. With the help of such an in depth analysis focusing on one person, we aim to bring the wife, mother, family member behind the soldier closer to the reader.
