Personalism is an intellectual stance that emphasizes the importance of human persons. Personalism exists in many different versions, and this makes it somewhat difficult to define as a philosophical and theological movement. Friedrich Schleiermacher first used the term personalism in print in 1799. One can trace the concept back to earlier thinkers in various parts of the world.

Nikolai Alexandrovich Berdyaev was a Russian philosopher, theologian, and Christian existentialist who emphasized the existential spiritual significance of human freedom and the human person. Alternative historical spellings of his surname in English include "Berdiaev" and "Berdiaeff", and of his given name "Nicolas" and "Nicholas".
