A conclave was held from 14 to 16 June 1846 to elect a new pope to succeed Gregory XVI, who had died in 1 June. Of the 62 eligible cardinal electors, all but twelve attended. On the fourth ballot, the conclave elected Cardinal Giovanni Mastai-Ferretti, the archbishop-bishop of Imola. After accepting his election, he took the name Pius IX. This conclave was the last to elect a ruler of the Papal States, the extensive lands around Rome and Central Italy which the Catholic Church governed until 1870.
