During the post-war period (from 1945 to 1950) Spadolini revised the majority of his old ideas, and became a moderate conservative to liberal. He also rejected his old anti-semitism for Zionism. He studied law at the University of Florence and shortly after graduation was appointed Professor of Contemporary History in the Faculty of Political Science. He also became a political columnist for several newspapers, such as "Il Borghese", "Il Messaggero" and "Il Mondo", becoming editor-in-chief of the Bologna paper "Il Resto del Carlino" in 1955, doubling its circulation during his tenure. In 1968, Spadolini moved to Milan where he took over the editorship of Italy's largest newspaper, "Corriere della Sera", a position he held until leaving journalism to enter politics. In 1972, he was elected as a senator, going on to serve as minister of the environment and then minister of education. Then in 1979, he was appointed secretary of the small but powerful Italian Republican Party (PRI).
