Thesis is dedicated to studying and analyses of the process of transformation of hellenized immigrants into the subjects of Ptolemies, who possessed absolute power over the country, and also to indication of influence of this process on the general historical development of Ptolemaic state. The difficult and longish process of transformation was objectively caused by necessity of overall submission of all residents of Hellenistic Egypt to the King's power – independently from their social or ethnic belonging. The goal of Ptolemies' internal policy was to absolute power over the country, which they saw, in the course of pharaonic tradition, as their own domain. The two main trends of internal policy, since Ptolemy I, were: evening-out hellenized immigrants to the level of Egyptian-type subjects, and defeating obstacles to such levelling. In both cases Ptolemies used the elements of Greek and Macedonian, as well as of local, political traditions. Among the measures, targeted to the levelling of country's population, we should name: inspiring stituation of general lawlessness before the King, creation of obedient, centralized, effective administrative apparatus, monopolization of system of "social amortization", implementation of dynastic cult and the practice of benevolent unintrusion into the process of adaptation of local religion by immigrants. Defeating obstacles to the levelling, which consisted of Hellenic priorities, colonizator's ideology of immigrants, and elements of Macedonian "legacy" (such as military assembly and the Council of King's "Friends"), was realized step-by step by the three first Ptolemies. Immediate results of this phenomena were: the absence of colonial situation nwithin the country, and international political passiveness of Ptolemaic Egypt, which started in the thirtieth of III ct. BC, and in the end became one of the main reasons of the downfall of the State of Ptolemies.
