Input: Question: In what locations did the Pope live for longer than 50 years? Passage:With the increasing chaos and disorder leading to the collapse of the Roman Empire in 476, the popes assumed more and more civil authority first in Rome and in the surrounding territories. Rome became the center of the Catholic Church and the capital city of the Papal States; consequently, a great number of churches, convents and other religious buildings were erected in the city, sometimes above the ruins of older pre-Christian sites of worship. Churches proliferated during the Renaissance, when the Rome's most notable churches were built (this includes St. Peter's basilica on the Vatican Hill (the largest church in the world) and the city cathedral of St. John at the Lateran. The Papacy established its residence first in the Lateran Palace, then in the Quirinal Palace. When Rome was annexed by force to the newly unified Kingdom of Italy In 1870, Pope Pius IX retired to the Vatican, proclaiming himself a prisoner of the Savoy monarchy and leading to decades of conflict between the neonate state and the Catholic Church. This was resolved in 1929, when the Lateran Treaty were signed in Rome, establishing the right for the Holy See to govern the Vatican City as an independent, sovereign state. The patron saints of Rome remain Saint Peter and Saint Paul (or, as they are collectively referred to in this context, "the most holy Saints Peter and Paul"), both celebrated on June 29.
