On leaving the military hospital in April 1945, he went to Adam Mickiewicz University in Poznań and then to Nicolaus Copernicus University in Toruń, where he earned a degree and a Ph.D. (1950).
Member of the anti-communist Solidarity movement – after the fall of communism in Poland, Kłoczowski was elected Senator and member of the Commission for Foreign Affairs of the Senate, as well as the representative of the Polish Parliament at the Council of Europe.

Jerzy Kłoczowski is a former lecturer at the Collège de France (1977), Merton College (Oxford University, 1980), University of Wisconsin–Madison (1985), Paris-Sorbonne University (1985–1987), Institute for Advanced Study in Princeton (1989–1990), College of Europe in Natolin, Warsaw (from 1997).

He was awarded the Order of the White Eagle, Virtuti Militari, Cross of Merit with Swords and Cross of Valor by the Polish government.
Professor Kłoczowski became a target of a slanderous controversy, resulting from an article published in Najwyższy Czas! magazine on September 11, 2004 (No. 37/747) by Stanisław Michalkiewicz. Michalkiewicz alleged that Kłoczowski could be the same person as the SB security agent pseudonym "Historyk" (Historian) recruited in 1961, and listed in the secret communist archives held by the Institute of National Remembrance.
Michalkiewicz wrote again about Prof. Kłoczowski for the Paris-based La Voix Catholique (The Catholic Voice) on November 7, 2004. His article resulted in a widely publicized official protest printed by Rzeczpospolita on November 13/14, 2004, and signed by 35 academics and prominent politicians such as Tadeusz Mazowiecki, Prof. Władysław Bartoszewski and film director Andrzej Wajda. The letter of protest explained that the slanderous memo (known as "Fałszywka" in Polish) was invented by the security service itself. The public protest was joined by the Catholic University of Lublin. Michalkiewicz was denied access to IPN archives in a decision that spurred further controversy lasting for several years. He was also discharged from La Voix Catholique.
