Boundary changes notably occurred after the dissolution of which political entity?

• A. The European Union
• B. The Ottoman Empire
• C. The British Empire
• D. The Soviet Union

Answer: (D)

When a large, multiethnic state breaks apart, the lines that used to separate its internal regions become international borders between new countries. After the Soviet Union dissolved in 1991, it split into 15 independent nations. Those republic borders that had been administrative within one state were now sovereign borders between different countries—Russia, Ukraine, Belarus, the Baltic states, and the Central Asian republics. This dramatically redrew the map across Europe and Asia, as new states established their own boundaries, border controls, and cross-border arrangements. The change wasn’t just about shifting internal lines; it created a whole new set of international frontiers that had to be recognized and managed by neighboring states.
