Pope Pius II
pope of the Catholic Church from 1458 to 1464 (1405–1464)

Pope Pius II (Latin: Pius PP. II, Italian: Pio II), born Enea Silvio Bartolomeo Piccolomini (Latin: Aeneas Silvius Bartholomeus; 18 October 1405 – 14 August 1464), was head of the Catholic Church and ruler of the Papal States from 19 August 1458 to his death in 1464.
Aeneas Silvius was an author, diplomat, and orator, and private secretary of Antipope Felix V and then the Emperor Frederick III, and then Pope Eugenius IV. He participated in the Council of Basel, but left it in 1443 to follow Frederick, whom he reconciled to the Roman obedience. He became Bishop of Trieste in 1447, Bishop of Siena in 1450, and a cardinal in 1456.
He was a Renaissance humanist with an international reputation. Aeneas Silvius' longest and most enduring work is the story of his life, the Commentaries, which was the first autobiography of a pope to have been published. It appeared posthumously, in 1584, 120 years after his death.
Early life
Aeneas was born in Corsignano in Sienese territory of a noble but impoverished family. His father Silvio was a soldier and member of the House of Piccolomini, and his mother was Vittoria Forteguerri, who had eighteen children including several twins, though no more than ten were alive at one time. The plague (iniqua lues) finally left him with only two sisters, Laudamia and Catherina. He worked with his father in the fields for some years.

Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
