This unit explains centrifugal forces, such as ethnic conflict in the former Yugoslavia and economic disparities in Catalonia, alongside centripetal forces like national iconography and equitable infrastructure that foster unity. Key historical events, including the Berlin Conference and the collapse of the Soviet Union, are analyzed to show how colonial and imperial legacies continue to shape modern borders.
