Mihailo Marković, born in Belgrade in 1923, was one of the most important Serbian Marxist-humanist philosophers of the twentieth century.

During the 1960s, Marković was one of the organizers of the Korčula Summer School in the 1960s, and was a member of the council of the philosophical magazine Praxis, which had a critical outlook on Yugoslav society. As a representative of this school of philosophy, he indirectly became one of the main critics of Josip Broz Tito and the League of Communists of Yugoslavia. Marković published his first texts in Polja in the spring of 1964. His articles, such as “Political Alienation and Self-management” (Polja, Issue  76, October 1964) and “Dialectics of Social Direction” (Polja, Issue 74, May 1964) dealt mainly with critique and ideas of communist development of communism within Yugoslavia. He worked as a strategist and participated indemonstrations at Belgrade University in 1968. In January 1975, alongside other colleagues from the Praxis, Marković was suspended from the Faculty of Philosophy  and later became one of the most prominent dissidents of the time.

Mihailo Marković lectured at several universities in Europe, Canada, and the United States. He was president of the Yugoslav Association for Philosophy (1960-62) and worked on the editorial boards of many other professional journals.
