can be considered a contemporary example of a war of conquest, taking into account that during the conflict there was, even if illegally in the eyes of international law, the
Russian annexation of Crimea and
parts of four southeast Ukrainian oblasts in 2014 and 2022, respectively. On the Russian precedent, Tanisha Fazal writes,
Norms die slowly. Attempted land grabs as big and brazen as Russia’s in 2022 are likely to remain rare, at least for now. But as aggressors go more or less unpunished, states may increasingly act on territorial claims in murky jurisdictions—those least likely to trigger a significant international response. These small-scale attacks may prove most damaging to the norm against territorial conquest. As violence ticks up, the larger web of rules and institutions that make up the international system could begin to come undone. Although far from inevitable, the norm’s demise would leave the world in dangerous terrain.
Leading to migration
Military conquest has been one of the most persistent causes of human
migrations. There is a significant influence of migration and conquest on political development and state formation. Conquest leading to migration has contributed to race mixture and cultural exchange. The latter points influence on conquest has been of far greater significance in the evolution of society. Conquest brings humans into contact, even though it is a hostile contact.

Subjugation
With subjugation, further class distinctions arise. The conquered people are enslaved; thus the widest possible social classes are produced: the
enslaved and the free. The slaves are put to work to support the upper classes, who regard war as their chief business. The state is in origin a product of war and exists primarily as an enforced peace between conquerors and conquered. From slavery and from conquest, another result of war, sprang differentiation of classes and occupations termed the
