What I’m positing is that there were three distinct waves of Indo-European migration (summarised in pp. 296–307 of my book). The first occurred in the post–Ice Age period, when Germanic-Slavic groups moved from the 9th millennium BC onward, as the northern and north-western regions became warmer and more fertile. The second wave involved those who had already settled in Anatolia and the Levant and then crossed the Mediterranean- Italo-Celtic speakers departing from the 7th millennium BC, settling Italy, France, and Iberia (the ancestors of Romance languages), while others continued through the Strait of Gibraltar in the 6th millennium BC and moved up the Atlantic coast to the western British Isles (the east having already been colonised by earlier Germanic speakers). The third and latest wave followed the Sarasvati collapse, bringing groups such as Luwians, Hittites, Mitanni, and others, including those who would become the Greeks. Some centuries later, these “Greek” kingdoms waged the conflict known as the Trojan War, largely for access to the food-rich Black Sea.
The phrase “some centuries” needs clarification, and this raises two key chronological questions. First: when did the Sarasvati dry up? The most convincing estimate - consistent with both Indian and international archaeological chronologies - is approximately 2000-1900 BC, a date that has been “approximately carbon-dated” (Nagarhalli, International Journal of Sanskrit Research, 2013, pp. 60–66). The second question concerns the date of the Trojan War. The conventional chronology offers 1188 or 1177 BC, but an increasing number of historians argue that these dates are flawed because they rely on extrapolations from Egyptological timelines that were never carbon-dated. The result is the notorious “300-year Dark Age” in which supposedly nothing occurred - no kings, no inscriptions, no pottery, no trade. This is not so much a Dark Age as an archaeological black hole, and clearly untenable. New interpretations now range from the 870s BC to the 940s BC. My own view is that the war occurred around 900 BC, for reasons detailed in my book. Interestingly enough, before Egyptologists defined their chronology and by inference the whole Mediterranean, Isaac Newton also thought about 900 BC. This would place it roughly a thousand years after the Sarasvati disaster that precipitated the final Indo-European migration. By the way, this flawed Bronze Age Mediterranean chronology is relevant to Indian history as scholars have used both carbon dating and Mesopotamian dates (dependent on Egyptian) causing much confusion.
As a related note, I have just finished
@subhash_kak's ‘The Sakka Language and Sanskrit’. Although it does not address this migration sequence directly, it is relevant in demonstrating how languages evolved during the final northern expansion. It is a superb piece of scholarship and well worth reading.
🧐 Not sure I understand this theory. Are you positing they were Yavana tribes from India?
