College of Cardinals, Pre- and Post WWII Pope, Pius XII.
One of this controversial pope’s many foibles was that he appeared not to think that highly of cardinals in general. Though he was pope for nearly 20-years he created but 56 cardinals — in just 2 consistories. Two consistories in 19.6 years! And WW II alone can’t be used as an excuse. Study my Excel spreadsheet above. Intriguing.
