The intelligentsia is a status class composed of the university-educated people of a society who engage in the complex mental labours by which they critique, shape, and lead in the politics, policies, and culture of their society; as such, the intelligentsia consists of scholars, academics, teachers, journalists, and literary writers.
Conceptually, the intelligentsia status class arose in the late 18th century, during the Partitions of Poland (1772–1795). Etymologically, the 19th-century Polish intellectual Bronisław Trentowski coined the term inteligencja (intellectuals) to identify and describe the university-educated and professionally active social stratum of the patriotic bourgeoisie; men and women whose intellectualism would provide moral and political leadership to Poland in opposing the cultural hegemony of the Russian Empire.
Before the Russian Revolution, the term intelligentsiya (интеллигенция) identified and described the status class of university-educated people whose cultural capital (schooling, education, and intellectual enlightenment) allowed them to assume the moral initiative and the practical leadership required in Russian national, regional, and local politics.
In practice, the status and social function of the intelligentsia varied by society. In Eastern Europe, the intellectuals were at the periphery of their societies and thus were deprived of political influence and access to the effective levers of political power and of economic development. In Western Europe, the intellectuals were in the mainstream of their societies and thus exercised cultural and political influence that granted access to the power of government office, such as the Bildungsbürgertum, the cultured bourgeoisie of Germany, as well as the professionals of Great Britain.
In a society, the intelligentsia is a status class of intellectuals whose social functions, politics, and national interests are (ostensibly) distinct from the functions of government, commerce, and the military.
