historians have interpreted the conclave to choose his successor as facing a choice between a diplomatic or a spiritual candidate, and they view Pacelli's diplomatic experience, especially with Germany, as one of the deciding factors in his election on 2 March 1939, his 63rd birthday, after only one day of deliberation and three ballots. He was the first cardinal Secretary of State to be elected pope since Clement IX in 1667. He was one of only two men known to have served as Camerlengo immediately prior to being elected as pope (the other being Pope Leo XIII). According to rumours, he asked for another ballot to be taken to ensure the validity of his election. After his election was indeed confirmed, he chose the name Pius XII in honour of his immediate predecessor. His coronation took place on 12 March 1939. Upon being elected pope he was also formally the Grand Master of the Equestrian Order of the Holy Sepulchre of Jerusalem, prefect of the Supreme Sacred Congregation of the Holy Office, prefect of the Sacred Congregation for the Oriental Churches and prefect of the Sacred Consistorial Congregation. There was however a Cardinal-Secretary to run these bodies on a day-to-day basis. Pacelli took the same papal name as his predecessor, a title used exclusively by Italian Popes. He was quoted as saying "I call myself Pius; my whole life was under Popes with this name, but especially as a sign of gratitude towards Pius XI." On 15 December 1937, during his last consistory, Pius XI strongly hinted to the cardinals that he expected Pacelli to be his successor, saying "He is in your midst." He had previously been quoted as saying: "When today the Pope dies, you'll get another one tomorrow, because the Church continues. It would be a much bigger tragedy, if Cardinal Pacelli dies, because there is only one. I pray every day, God may send another one into one of our seminaries, but as of today, there is only one in this world." Appointments After his election, he made Luigi Maglione his successor as Cardinal Secretary of State. Cardinal Maglione, a seasoned Vatican diplomat, had reestablished diplomatic relations with Switzerland and was for many years nuncio in Paris. Yet, Maglione did not exercise the influence of his predecessor Pacelli, who as Pope continued his close relation with Giovanni Battista Montini (later Pope Paul VI) and Domenico Tardini.
