Cardinal electors for the 1903 conclave

The conclave of 1903 was convened to elect a pope, the leader of the Catholic Church, to succeed Pope Leo XIII following his death on 20 July 1903.

Of the 64 members of the College of Cardinals at the time of Leo XIII's death, 62 participated in the subsequent conclave, the largest number to enter a conclave up until that time.^[1][2] Francis Patrick Moran arrived after the new pope had been elected, while Michelangelo Celesia was unable to participate due to ill health.^[2]

Of the 62 attending electors, 6 were cardinal bishops, 48 were cardinal priests, and 8 were cardinal deacons. Only the Dean, Luigi Oreglia di Santo Stefano, was a creation of Pope Pius IX, with the remaining 61 cardinals having been elevated by his successor Pope Leo XIII.

The oldest cardinal elector in the conclave was François-Marie-Benjamin Richard de la Vergne, at the age of 84, and the youngest was Lev Skrbenský z Hříště, at the age of 40.

This was the first conclave to host a representative from North America—James Gibbons, Archbishop of Baltimore—and the first to incorporate a non-European born cardinal since the 1471 papal conclave that featured Cardinal Bessarion of Trebizond.^[3]

The cardinal electors entered the Sistine Chapel to begin the conclave on 31 July 1903. On 4 August, after seven ballots over five days, they elected Cardinal Giuseppe Sarto, the Patriarch of Venice, who took the papal name Pius X.^[4]
