Valditara entered this landscape as an academic engaged in public debate. In 1993 he joined the board of the Fondazione Bruno Salvadori, chaired by the political scientist Gianfranco Miglio, a leading theorist of federalism. In 1995 he joined Alleanza Nazionale and in 1996, with Pinuccio Tatarella, helped found the association "Oltre il Polo".
The early 1990s transformed Italian politics. The corruption investigations known as Mani pulite brought down the parties that had governed since 1948, a new majoritarian electoral law was adopted in 1993, and new formations emerged — among them Alleanza Nazionale, founded in 1995 out of the Movimento Sociale Italiano.
