The Katyn massacre was a series of mass executions of nearly 22,000 Polish military officers and intelligentsia prisoners of war carried out by the Soviet Union, specifically the NKVD in April and May 1940. Though the killings also occurred in the Kalinin and Kharkiv prisons and elsewhere, the massacre is named after the Katyn forest, where some of the mass graves were first discovered by German Nazi forces.

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.
In Russia, the writer Pyotr Boborykin defined the intelligentsia as both the managers of a society, and as the creators of society's high culture.
