As the Littoral Croatian Duchy became a Kingdom after 925, its capitals were in Dalmatia: Biaći, Nin, Split, Knin, Solin and elsewhere. Also, the Croatian noble tribes, who had a right to choose Croatian duke (later the king), were from Dalmatia: Karinjani and Lapčani, Polečići, Tugomirići, Kukari, Snačići, Gusići, Šubići (from which later developed very powerful noble family Zrinski), Mogorovići, Lačničići, Jamometići and Kačići. Within the borders of ancient Roman Dalmatia, the Croatian nobles of Krk, or Krčki (from which later developed very powerful noble family Frankopan) were from Dalmatia as well.
