Lateran Treaty
Negotiations for the settlement of the Roman Question began in 1926 between the government of Italy and the Holy See, and culminated in the agreements of the Lateran Pacts, signed—the Treaty says—for King Victor Emmanuel III of Italy by Benito Mussolini, Prime Minister and Head of Government, and for Pope Pius XI by Pietro Gasparri, Cardinal Secretary of State, on 11 February 1929. It was ratified on 7 June 1929. The agreements were signed in the Lateran Palace, hence the name by which they are known.
Station days
After the Lateran Treaty of 1929 solved the Roman Question, Pope Pius XI and Pius XII encouraged a return to the ancient tradition by attaching indulgences for visiting the station churches of Lent and Easter. Concrete gestures on the part of Pope John XXIII and Paul VI also began a revival, as John XXIII was the first pope in modern times to celebrate Ash Wednesday at Santa Sabina, and Paul VI visited Sant'Eusebio on its station day in 1967.
