Aggressors may deliberately create and maintain unbearable socio-economic conditions (acute land shortage, crushing obligations, destitution) in the historical territories of an Indigenous people. This is done to force the population to flee physical and social ruin. As a result, the people 'voluntarily-compulsorily' join the colonizer's militarized structures (for example, the Cossack host or the regular army) or migrate en masse to dangerous imperial frontiers to settle them. This technique allows the empire to accomplish its military and colonization objectives by proxy, disguising state coercion as the victims' own 'free economic choice.'
