The geopolitical reality of the Slavic peoples—historically and geographically wedged between a Greater Germany, Turkey (the Ottoman Empire), and Russia—lies at the heart of the turbulent history of Central and Eastern Europe. 

For centuries, this vulnerable belt of countries and ethnic groups has served as a buffer zone, forced to navigate the great-power ambitions of three expansionist empires. 

Geopolitical fault lines: The Slavic peoples caught in this "sandwich" can broadly be divided into two geographical groups, each subject to distinct imperial pressures: The West Slavs (Poles, Czechs, Slovaks): Situated directly on the North European Plain, squeezed between German expansionism to the east (*Drang nach Osten* / Greater Germany) and the Russian Empire to the west. 

Poland’s history—marked by the partitions of the 18th and 19th centuries and the invasions of World War II—stands as the most striking example of this existential predicament. The South Slavs (Serbs, Bulgarians, Croats, Slovenes, Bosniaks): Located in the Balkans, a region that for centuries served as a battleground between the Austro-German (Habsburg) Empire to the north, the Ottoman Empire (Turkey) to the south, and the Russian Empire, which sought to push southward toward the Black Sea and the Mediterranean under the banner of Pan-Slavic solidarity. 

Historical defense strategies: Intermarium. To withstand the pressure from these colossal neighbors, the Slavic states of Central Europe have repeatedly attempted to organize themselves into alliances. 

The most famous geopolitical doctrine is Intermarium (Latin for "between seas"), originally conceived by the Polish leader Józef Piłsudski after World War I. The concept entailed creating a large federation or coalition of states stretching from the Baltic Sea to the Black Sea (and ideally the Adriatic Sea). The goal was to establish a third power bloc strong enough to collectively repel both German and Russian imperialism.
