In the mid to late middle ages a mixture of Franks (basically French - but often a long time wandering around the Mediterranean), Italians - primarily Venetians, Pisans and Genoese - and Catalans all made their historical mark on Greece. However the underlying Greek speaking populace remained pretty constant and these conquerors and rulers have left little trace of their occupation save the medieval castles which dot the hilltops and the extremely rare examples of gothic features in churches. Of Frankish culture it is hard to find any traces whatsoever such was the hold of the Orthodox Church on the imaginative horizons of the population. One caveat - to talk of nation states in the medieval period is to project and impose modern ideologies and cultural and ethnic preconceptions back into a past where they would not be recognised.
