The conclave that begins May 7 is expected to be the largest in history, with a wide geographical mix of cardinal-electors.
There are 135 cardinals under the age of 80 and eligible to vote in a papal election. By contrast, 115 cardinals took part in the conclaves in 2005 and 2013.
The cardinals represent 72 different countries if one counts the nations where they are serving and not just where they were born. Take the example of three Italians: Cardinals Pierbattista Pizzaballa is the Latin patriarch of Jerusalem; Giorgio Marengo is the apostolic prefect of Ulaanbaatar, Mongolia; and Mario Zenari is the apostolic nuncio to Syria.
