This alternate-history map shows the extent of the Empire of Lithuania, around the 18th-19th century.
The timeline changed during the 14th-15th century, with Grand Duke Vytautas achieving victory in the Battle of the Vorskla River, and expanding further into far Ruthenia. As a result, Vytautas continues working on his plans, eventually breaking the Union of Krėva and becoming King of Lithuania.
Over time, the Kingdom of Lithuania expands further and further east through its southern territories, taking over weakened Khanate territories before Russia could, and thus ends up reaching the Pacific Ocean, dominating over northern Asia.
Now, centuries later, the Empire of Lithuania is a great world power. Its primary language is Lithuanian, although various provinces in the west are mostly autonomous and thus use the their own languages ( like, for example, White Ruthenia/Belarus use the Ruthenian language ).
Before anyone decides to point this out, know that I am aware that this map is somewhat implausible. I am also aware that the imperial province/territory names are barely, if at all, readable - it was intentional, since I don't know any alternative far-eastern Russian territory names.
This was made using GIMP v2. I used the MEIOU ( it's an excellent Europa Universalis III mod ) world map as a basemap for the territory and geography shapes.
The fonts used aren't made by me - I found them on DaFont.
