Perhaps the ultimate responsibility for the development of the colonate may rest upon the attempt of the imperial government to incorporate within the empire vast territories in a comparatively low state of civilization, and upon the fiscal system whereby it was designed that the expenses imposed by this policy should be met. In the West the administration strove to develop a strong class of prosperous peasants as state tenants; in the East its object was to maintain this class which was already in existence. But the financial needs of the state caused such a heavy burden to be laid upon the agricultural population that the ideal of a prosperous free peasantry proved impossible of realization. The ravages of war and plague in the second and third centuries also fell heavily upon the peasants. As a last resource to check the decline of agriculture the government placed the small farmer at the disposal of the rich landlord and made him a serf. The results were oppression, poverty, lack of initiative, a decline in the birth rate, flight and at the end an increase of uncultivated, unproductive land. The transplanting of conquered barbarians within the empire swelled the class of the _coloni_ but proved only a partial palliative to the general shrinkage of the agricultural elements. But the converse to the development of the colonate was the creation of a powerful class of landholders who were the owners of large domains exempt from the control of municipal authorities.
