look at italy south of parma mass immigration and miscegenation happened in italy under the romans just like what's happening now, and the left over mutts then got further muttified by the germanic invaders who pulled them northwards genetically, but not to the same degree as they were before the mass migration when most of italy genetically resembled modern day lombards or catalans i guess like the modern day italians they will larp as their unmixed ancestors but like modern day italians nobody will take them seriously
