What if the Romans had spoken Etruscan instead of Latin?
Etruscan speaking Rome would create very different culture and so history would be unrecognsible. Romans hardly would be OTL Romans if they would speak Etruscan instead Latin. There would be great cultural shift.
How would the other Italic nations develope ? Like the Samnites.What if the Romans had spoken Etruscan instead of Latin?
If we assume that Rome emerges to dominate the Etruscan lands, that is.

Probably not. Late Iron Age Imperialism in the Med does appear not to have cared much for such sort of ethnolinguistic considerations in general (ethnicity was important, but was seen in genealogical, not linguistic, terms). Also, as Falerii being linguistically (almost) Latin and politically Etruscan shows, there is no reason to think that an Etruscan-speaking Rome wouldn't have been involved in a ATL equivalent of the Latin League (Roman and Latin political identities are distinguished in OTL's sources by the way, betraying the mixed nature of Roman citizenry, and, likely, of her culture too). The League was not apparently defined in linguistic terms (I think some members were Oscan-speaking cities, for instance, though I am not sure). Also, if Rome is predominantly Etruscan, the fate of Latin as a language in the rest of Latium may be problematic from an early date.Would the first imperialistic imperative for Rome in this timeline be the uniting of all Etruscans as opposed to Latins?
It is useful to note that whatever really happened when the Tarquinians were expelled from Rome closely parallels what was going on in other Etruscan polities, for the little we know about it (and may be comparable to contemporary upheavals in some Hellenic poleis and later ones in Carthage; we have not enough info on other autonomous Phoenician cities in the Middle and Western Med, but one can suppose the general trend was shared - it may have something to do with the Persian Empire).
What exactly caused the creation of republican regimes in the 6th and 5th century? Within some decades, nearly all Greek cities abolished their archaic monarchies and opted for aristocratic constitutions - in Athens, they even adopted a democratic organization before the end of the century. And even the cities that maintained their monarchical institutions heavily limited the power of their kings. Was this a Greek phenomenon which inspired Rome and Carthage (both cities who also abolished monarchy) - or was it a development affecting all city states, Greek, Etruscan and Phoenician ones?
Another interesting institution of the time is tyranny. While tyranny mainly affected Greek cities, some historians have described the Etruscan kings of Rome as tyrants. Roman and Greek sources credit one of them (Servius Tullius) with the creation of the centuriate and (new) tribal organization. And indeed, Greek tyrants often paved the way for more popular constitutions by weakening the nobility. I wonder if the reign of the Etruscan kings was crucial in shaping Rome's social organization - and if one of the reasons for the abolition of Roman monarchy was that the patricians opposed tyrannic policies favoring the plebeians.
Wait, you post on Roman threads? I thought anything pre-Charlemagne didn't interest you.
