The article analyzes the historical aspects of the emergence and formation of higher education in the countries of the Romano-Germanic legal family. It has been found that the traditions of higher education are laid down in the University of Bologna, which became the first famous secular scientific and educational institution, whose professors and graduates enriched science and education with new ideas, thanks to which a new humanistic worldview was formed: law should be a measure of freedom and justice in the state and society. It is substantiated that the development of education has a civilizational significance in the state-building process, but the civilizational «growth» of the state requires professional human capital. An important source of information for acquiring a system of knowledge in medieval Europe was Roman private law, which was universal in application to new economic and other conditions, regardless of their complexity. The merit of the Roman jurists is that they formalized the customary law and supplemented and developed it according to social needs. It has been proven that Roman law was «safe» for medieval rulers and in fact indispensable for the maintenance of various types of private legal relations, so there was no reason to oppose its introduction into the educational process. It was concluded that the study of Roman law in the medieval universities of Europe led to the assimilation of the formation of the legal system in a number of European states and the formation of the Romano-Germanic legal family, because the principles and norms of Roman law formed the basis of European codifications. It is important that the law of the Romans was used as an active law even in those states that did not have a legal mechanism for solving controversial issues, especially in interstate relations, because this law is saturated with classic examples of solving various life situations. Addressing them contributed to the development of the student’s skills not only in legal analysis and thinking, but also in the practical selection and application of normative material in order to solve life’s legal problems.
