Vatican City - The change of the pope (through death or resignation) is a complex process, with centuries-old rituals involving the transition of leadership to the spiritual heads of the Catholic Church and the Vatican heads of state around the world.

These are the terms to know – some of them in Latin – that helps to get to know the news in the days to come:

There are 252 cardinals around the world, as a body, who are responsible for the affairs of the Popes between the Popes, despite being subject to the limits. Of these, 135 were "cardinal voters" who gathered in the Vatican to choose the new pope. Only 133 people attended the meeting because two were sick. For centuries, they have chosen one of their own. Vatican statistics show that the vast majority of voters (108) are appointed by Pope Francis.

It was a closed-door meeting of cardinal voters to choose the new pope of Sistine Church. Its name is actually "with keys", and was used in the 13th century to describe the process of locking the cardinal until the election is completed. It must not exceed 20 days after the Pope dies or resigns. During this period, voters were quarantined by all outsiders. The last three popes were chosen within a few days.

The current dean is the Italian Cardinal Giovanni Battista Re. He was the principal of the Cardinal College, who once he learned of the Pope's death from Camerlengo and put his other cardinals and ambassadors in the Pope's death. He called a meeting and was sworn in after the voters. Since RE is 91 years old, he cannot vote, so once the meeting begins, he will leave the Sistine Church and the highest-ranking Cardinal Pietro Parolin takes over Cardinal Pietro Parolin.

The 16th-century church was built on the traditional tomb of the Apostle St. Peter. It is one of the largest Catholic cathedrals in the world and is the core of the Vatican city, which is the headquarters of the 1.4 billion Catholic churches. The masterpiece of the Renaissance was built and decorated by the most outstanding architects and artists of the time. Its grottoes contain the remains of the Pope, and its vast, marble interior is home to the Vatican's greatest treasures, including the sculpture of Pieta by Michelangelo and the bronze bald canopy of Gian Lorenzo Bernini on the main altar.

The Vatican hotel was built in 1996, especially with a cardinal during one session, and was used at other times as a hotel for visiting pastors and Vatican officials. Pope Francis never moved out after being elected and chose to live in a 201 apartment instead of the Pope's apartment in the Apostle's Palace. Because there were many voters this time and there was not enough space in the main building, some were placed in adjacent residences.

The master of the Pope's liturgical celebration (currently Italian Archbishop Diego Ravelli), asked all cardinal candidates to leave Sistine Chapel to begin the voting process during the meeting.

This Latin phrase translates to "we have a pope." These are the words announced by Cardinal College’s “Protodeacon” in St. Peter’s Basilica Gallery, saying that a new pope has been elected. Then, he said, the new pope's last name and the name he chose to use as the pope, was also Latin. The current original principle is French Cardinal Dominique Mamberti.

These are the three cardinals selected by the random paintings of voters, who are accused of collecting any votes given to Rome but who were sick during the meeting.

These are three cardinals selected by random paintings of voters, who are accused of reviewing each vote and announcing it to the meeting of the rally after each round of votes. Then they counted the ballots - two-thirds of the ballots were necessary to win the election - they burned the ballots.

This is the Latin word for "vacancies", a period between the death or resignation of the pope and the new election.

This Latin means "the whole flock of the Lord." It is the Vatican Constitution that regulates these procedures from the death of the pope until the election of the new constitution. St. John Paul II released it in 1996 during his Pope during his Roman Pope, which Pope Benedict XVI revised twice, and most importantly, removed John Paul's provision that, about 12 days after the vote, a simple majority could elect a new pope, rather than two-thirds of the pope. If the conclusion lasts so long, the top two voters will enter runoff, with two-thirds of the majority required to win. Neither of the first two candidates voted in runoff.

After the voting meeting at Sistine Church, ballots were burned in a special furnace to show the outcome to the outside world. If the Pope is not selected, the ballot is mixed with a cartridge containing hyperchloropotassium, anthraxone (the component of coal tar) and sulfur to produce black smoke. If there is a winner, the burning ballot is mixed with potassium chlorate, lactose and chloroform resin to produce white smoke. The bells are usually ringed to further send out a new pope.
