his political career was very fast. in 1945 he became vice-secretary of democrazia cristiana and on 2 june 1946 was elected to become part of the "costituente" (the political body in charge of drafting the new italian republican constitution), of which he became one of the most active members. exactly he took part of the first subcommission in charge of the "rights and duties of the citizens". in 1946, with amintore fanfani, giorgio la pira and giuseppe lazzati (described, not without a bit of deprecation, as "little professors") he founded the association "civitas humana".
