The description on its file description page there is shown below.
The factual accuracy of this map or the file name is disputed.
Reason: Unsourced map. Furthermore, there are numerous verifiable errors. For instance, Erivan/Yerevan was gained in 1828 through the Treaty of Turkmenchay (thus not 1826), whereas Baku/most of the Azerbaijan Republic was gained in 1813 through the Treaty of Gulistan (thus not 1806).
The factual accuracy of this map or the file name is disputed.
Reason: 'Eastern Europe' should be: Central Europe. The European part of Russia alone is already 40% of Europe; Europe's midpoints are east of the territories marked on the map as Eastern Europe.
