The exact timeline of the Indo-European migrations and their arrival in the Aegean is a subject of ongoing research and scholarly debate. However, based on the current understanding, the first Indo-Europeans likely appeared in the Aegean region around the late 4th millennium BCE or the early 3rd millennium BCE.
During this period, there was a significant movement of people across different regions, and it is believed that speakers of the Proto-Indo-European language began to migrate from their homeland, possibly located in the Pontic-Caspian steppe region (present-day Ukraine and southern Russia). These migrations led to the spread of Indo-European languages and cultures across a vast area, including the Aegean.
The arrival of Indo-European speakers in the Aegean is associated with significant cultural changes in the region, including the introduction of new languages, technology, and social structures. This period also marks the transition from the Neolithic to the Bronze Age in the Aegean, which brought about the rise of complex societies such as the Minoans and Mycenaeans.
It's important to note that the timeline and specific details of these migrations are still subjects of ongoing research, and new discoveries and interpretations may provide further insights into the early Indo-European presence in the Aegean
