I want to know the answer to the following question:
In what year did Pope Sixtus V put a cap on the number of cardinals in the College of Cardinals?
All the background I'm provided with is that "While the number of cardinals was small from the times of the Roman Empire to the Renaissance, and frequently smaller than the number of recognized churches entitled to a cardinal priest, in the 16th century the College expanded markedly.". Is that enough to answer the question?
Answer: no
