Is there a fixed rule that decides whether to read a Roman numeral as a cardinal number or an ordinal number?
For Example, WWII, we say World War Two, but Queen Elizabeth II, Queen Elizabeth the Second. Minsk II agreement is also read as Minsk Two agreement.
(Yes, we can say the Second World War and the Second Minsk Agreement as well.)
Again, my question is whether there is a fixed rule that dictates the way Roman numbers are read in title or name (like citation guidelines we used in college), and if so, what would that be.
