          Iceland and Norway who, under their leader Rollo, agreed to swear fealty to King Charles III\
          of West Francia. Through generations of assimilation and mixing with the native Frankish and\
          Roman-Gaulish populations, their descendants would gradually merge with the Carolingian-based\
          cultures of West Francia. The distinct cultural and ethnic identity of the Normans emerged initially\
          in the first half of the 10th century, and it continued to evolve over the succeeding centuries."
