Vatican City: Over the past century, no conclave has lasted more than five days and the fastest vote was for Pope Pius XII. Twice prelates from North America missed the vote because they couldn't get to Rome in time, and a Hungarian cardinal sat out two conclaves because he was holed up in the US Embassy in Budapest seeking asylum.
