Today most of Europe is inhabited by Indoeuropean people, with a few exceptions
Four of them are Turkey, Hungary, Estonia and Finland. These four nations have populations and languages that come from Central Asia
In the case of the Hungarians and the Turks we understand fairly well the history of the migrations and wars that brought them there, but what about Estonia and Finland?
Even more, were Estonia and Finland settled during the same migration?. They have similar languages after all
I've tried researching this on my own but most of the information I find starts around the Middle Ages with both countries already settled by people speaking Uralic languages
Information about the Iron and Bronze ages is extremely limited, but presumably that's when this migration happened
Recent genetic studies have ruled out any large mass migrations into Estonia over the last 20-25 centuries (except the most recent soviet colonisation). And regardless of the timing, finnic language arrived to Estonia from south (via Prussia or via Smolensk along the river Väina / Daugava), not from east nor from north.
Uralic peoples are native to northern europe, uralics didn't arrive from central asia.
Uralics have always been to the north of indo-europeans. And the most populous uralics have always been at the southern sphere of uralics - at the hemiboreal and forest-steppe zones. Most of the finnics lived to the south of the Bay of Finland until the Livonian War. And at the start of the local iron age at least 50% of the Baltics was still finnic.
Genetic autosomal WHG component (West Eurasian Hunter-gatherers) peaks among finnic estonians (Lazaridis et al, 2014). The continuous small scale immigration during bronze and early iron ages happened as part of bronze age viking trade along Väina / Daugava with the volga finnics - about 1-10 persons annually.
There have never been a compact proto-estonian language, no compact proto-finnic language, no compact proto-finno-samic, no compact proto-western finno-ugric nor compact proto-finno-ugric nor compact proto-uralic language - all those have always been sprachbunds.
