The aim of the study was to point the importance of the Hlohovec branch of the Aba family. It owned and created not only the castle lordship of Hlohovec, but also Dobrá Voda or Branč. Therefore, it is important for knowledge of this region in the second half of the 13th and beginning of the 14th centuries. The study also devotes attention to the architectural monuments and archaeological finds of this period from Hlohovec. It describes the domain of the Aba family not only in the immediate surroundings of Hlohovec, but also in the Galanta district. It traces the fate of Hlohovec, closely connected with the Aba family in the period 1276–1316. Finally, it considers the property exchange between the Aba family and Abraham Rufus in 1297 and the granting of a second settlement to Abraham Rufus of Červeník in 1294 and his military achievements.
