Konstantinos Tsatsos: The Philosopher Who Drafted the Modern Greek Constitution

Ideas & Philosophy · Published 3 October 2026 Swipe more like this →

In short: Before serving as the second President of the Third Hellenic Republic, Konstantinos Tsatsos was a distinguished professor of legal philosophy. His career bridged the gap between abstract jurisprudence and the practical realities of statecraft, culminating in his leadership of the commission that drafted Greece's new constitution in 1974.

Born in Athens in 1899, Konstantinos Tsatsos pursued an academic path that took him to Heidelberg, Germany, for doctoral studies between 1924 and 1928. Upon his return to Greece, he became a professor of law in 1933, a position he held until 1946. His intellectual output was prolific, spanning textbooks on legal theory, essays on the philosophy of law, and translations of ancient Greek and Roman classics. His scholarly work, including titles like 'The Problem of the Sources of Law' and 'Studies on the Philosophy of Law', established him as a significant voice in legal science.

Tsatsos's life was deeply intertwined with the turbulent political history of 20th-century Greece. He was exiled in 1940 for opposing the 4th of August Regime and later participated in the Greek Resistance during the Axis occupation. Despite his ideological roots as a centrist-liberal, he became a key colleague of Constantine Karamanlis and a member of the National Radical Union in 1955. His political career included various ministerial roles, most notably as Minister for Culture following the 1974 Metapolitefsi.

Perhaps his most enduring legacy is his contribution to the institutional foundation of contemporary Greece. In 1974, he presided over the parliamentary commission responsible for the first draft of the new constitution. This work preceded his election as President of the Republic in 1975, a role he held for a five-year term. Beyond his political and legal achievements, he was a member of the Academy of Athens and maintained a lifelong engagement with literature and poetry, famously engaging in a published dialogue with his brother-in-law, the Nobel laureate George Seferis.
