The star has some resemblance to the image of the sun on the Argentine flag, but I don’t know if that is intentional.
But that star kind of escaped me at first, but lo and behold I've already gone over the dispute between King Philip I/II ~ former husband of Queen Mary ~ and all the other Catholic authorities over sending missionaries to the Americas, particularly North America. The Jesuits seemed to have gotten a monopoly! That was withdrawn ~ and by 1604 the Spanish were carving up North America and giving away part of it to the Russian Orthodox and the European Protestant movement.
