Why might you suspect that the borders of the countries in central and Eastern Europe have often changed as political changes occur?

The borders of countries in Central and Eastern Europe have frequently changed due to historical factors such as the dissolution of empires, the aftermath of wars, and shifts in political ideologies. Events like World War I and II, the fall of the Iron Curtain, and the subsequent rise and fall of various regimes led to redrawing boundaries to reflect new political realities or national identities. Additionally, ethnic tensions and desires for self-determination have often fueled demands for territorial changes. This dynamic interplay of history, politics, and ethnicity has made the region particularly susceptible to border changes.
