first map of lithuania has poor eastern borderaround kursk and rylsk the border ended at those 3 subjects of lithuania, see image:from the sea border followed dnieper, at modern city of Dnipro where samara river branches off the border followed the river, that was said in peace deal between crimean khanate and lithuania, when lithuanians seized yedisan and other surrounding territories, but your border seems to show a PLC border.novgorod side is ok you got the detailsupper oka is shown as being lost first, but it wasnt land owned by lith, it was a bunch of minor states in sphere of influence of either lithuania or muscovy, who influences who switched around with the local politics, who was viewed as agressor, and who had taken the title of grand principality of rus (both muscovy and lith called themselves grand principality, though lith is translated as duchy into english probably to distance from slavs, and both claimed the title of grand duke of ruthenia/russia, and muscovy / lith ceded the title to each other in quite a few peace deals)heres a random map for upper oka, though it seems to show it as part of lith, you have to check the wiki and find all the minor city-state tags, i remember seeing plenty of themin the second map the stick with Wielki was lost somewhen earlier / separately. www.hist-geo.net/media/blogs/b… you actually figured that lith didnt own tauroggen/taurage, but they also had a hole in the country, prussia owned seirijai, though i remember reading on tauroggen how lith got back that stuff during 2nd partitionakniste, the bit that pokes into latvia was a panhandle of lith since 17th century, so it shouldnt appear on first mapi dont know if you knew but lithuanias northern border was different before.apart from akniste, lithuania lost the area that is latvia colored inside lithuanias side of white line, because latvia returned palanga coastline to it, see lehnarus map:bonus history fact: in 1450s lithuania and muscovy agreed to a kind of molotov-ribentrop pact, where muscovy conceded principality of tver to lithuanian sphere of influence and gave a little area to connect lithuania with tver, but they also signed to not intervene in each others wars or war each other, this lasted until 1490s when muscovy attacked lith. muscovy needed this deal to conquer novgorod without lithuania joining, if not this deal muscovy would be defeated and novgorod would be capital of russia prollytver shape www.e-reading.club/illustratio…
