Conti di Segni
The family began with Trasimondo, the father of Lotario Conti, who became Pope Innocent III in 1198. He ruled until 1216. The second Conti pope was Ugolino (1227-1241), as Gregory IX. The third pope to come from the Conti family was Rinaldo, as Alexander IV (r. 1254-1261). Later, in the early modern period, Michelangelo Conti reigned as Pope Innocent XIII from 1721 to 1724.
