This mod adds Historical Borders to the Game.
In 1.6 “Ironclad” update, Paradox added many new tags and with them, changed the borders of many regions to the post-war or present day borders. This had very negative impact on the borders of Eastern Europe. Update ruined possibilities to re-create iconic WW2 borders such as Molotov-Ribeentrop, patritions of Yugoslavia and many more.
Mod removes post-war borders added in 1.6 and replaces them with pre-1.6 borders which were altered a little bit to better represent borders of European countries during WW2.
This mod also adds 10 new historical regions for better possibilites of recreating historical borders of some countries, such as Kingdom of Hungary or German Empire.
