The papal conclave, October 1503 elected Giuliano della Rovere as Pope Julius II to succeed Pope Pius III and was only 10 hours long.
Pope Urban chose the name upon his election as pope.
Before the election of Pope Francis there was never a pope from any of the Americas.
He chose the name Leo at the time of his election as pope.
He became pope on April 19th 2005.
Pope Francis is the first jesuit to be elected as pope, the first pope from the America's and the first pope in many centuries who is not from Europe.
When the ballots are burned after the successful election of the new pope, the smoke issuing from the chimney of the Sistine Chapel is white.
No, who the new Pope will be is always unknown until his election by the cardinals.
I am not sure what you are referring to in your question. However, the moment a pope is elected and he accepts the office, he is the pope. A few days after the election a ceremony is held that officially installs him in office. It was formerly called the Papal Coronation. A few days after the installation, the pope goes to St. John Lateran, the official cathedral of the Diocese of Rome, and takes possession of his church as the Bishop of Rome. Besides holding the title of Pope, he is also the Bishop of Rome.
This is not a political election and no one 'runs' for pope. The pope is generally chosen from among the cardinals. They do not campaign for the position.
An antipope is a person who claims or claimed to be the pope as the result of a disputed election, but is not considered to be the real pope.
It is called a conclave.
