The history of the European continent is mind-blowing complicated. That’s why the borders of many European countries often unpredictable have changed many times.
Below are maps illustrating the most radical changes in state borders in European history.
Medieval Europe (5th-15th century)
Medieval Period began with the collapse of the Western Roman Empire. Numerous Germanic peoples created new kingdoms in what remained of the Western Roman Empire.
Rome’s direct sequel, the still-substantial Byzantine Empire, remained in the Eastern Mediterranean and persisted a significant power.

Early modern Europe (late 15th century – late 18th century)
Early modern Europe is a period of European history starting with the Ottoman conquering of Constantinople in 1453, the Renaissance period in Europe, and the end of the Reconquista. Feudalism waned.
Europe, 1500 A.D.
In Europe sparked the fierce Thirty Years’ War and ended with the founding of the contemporary international system in the Peace of Westphalia.
This treaty had a significant impact on Germany by confirming the territorial sovereignty of Germany’s many political bodies, the Treaty of Westphalia increased and perpetuated german division and political weakness. Austria and Brandenburg-Prussia, however, gained international significance during the age of the treaty.
During this time distinctive nation-states firmly established the competitive nationalism of the modern world.

As the winds of the democratic revolution swept across Eastern Europe, Communist control breaks in the nation after nation.
The fall of the Berlin Wall in 1989 was the first sign of destroying the post-war borders. Then the USSR and Yugoslavia collapsed in 1991. Belarus, Ukraine, Moldova, Estonia, Lithuania, Latvia, Croatia, Slovenia, Bosnia, and Macedonia are added to Europe’s map. By the end of 1992, Czechoslovakia was divided into the Czech Republic and Slovakia. There are now 22 new nations in Europe.
