Raf clears the table! (Been practicing billiards lately?)
A) 1605 was the last time- before JP1- that there were 3 different Popes in the same calendar year. It has to coincide with the conclaves agreeing in a few months on the next pope, and a pope dying after a short term in office. So, one pope dies, the conclave selects the next pope quickly, who also dies, and the conclave picks his successor quickly. So, in one calendar year, that happened with JP1 but hadn't happened for the previous 450 or so years.
B) JP1 picked two names- John and Paul, which was unique in papal history. First time ever.
C) JP1 called himself "the First" rather than simply "Pope John Paul", and that also was a first.
D) 3 previous popes had officially been poped and had died shorter into their terms than he did, but since those weren't recent, a lot of conspiracy theories popped up.
