The 1243 papal election (16 May – 25 June) elected Cardinal Sinibaldo Fieschi of Genoa to succeed Pope Celestine IV. The conclave began after the Holy See had been vacant for 18 months and six days, therefore ca. May 16, 1243. There were nine cardinals present. Six votes were needed, therefore, for a canonical election. It took some five weeks for the cardinals to agree on an acceptable candidate. Fieschi took the name Innocent IV.
