According to "Gesta Hungarorum", Vlach political formations located in the north and northwest of Transylvania, led by Gelou, Glad, and Menumorut were conquered by the Hungarian tribes at the beginning of the 10th century. During the Menumorut voivodeship, the defense of the salt road was ensured by the fortresses from Ocna Dej and Cuzdrioara and the fortified points from Uriu and Urișor. The extension of the Kingdom of Hungary to the center and south of Transylvania was achieved with the help of Székely and German settlers. The first settlers arrived in the Dej area in the years 1141–1143, entering from Satu Mare to Dej, Bistrița, Cluj, and Reghin. After leaving Holland and Flanders because of the floods of the sea, they settled in this region and founded the city of Dej.
