During the middle ages, how did the catholic religious leaders influence the kings and lords of europe?

a: the church usually had bishops and cardinals made into kings.
b: the church had an army larger then any other feudal army.
c: the church taught that it had authority over every person.
d: the church had control over most of europes food supply.

the three answers (for plato at least) are:

b-condemned sola fida 

d-set rules for establishing seminaries and for educating clerics in the seminaries 

f-recommended moderation in the sale of indulgences and banned the sale of false indulgences 

well this is going to be a long answer lol ok so the visigoths were a branch of the goths who frequently raided rome, uh the hunas attacked the guptas a lot and weakened them, uuhm of course the romans used math and science in there every day lives i mean they had a whole empire to run, and rome was split into east and west by a general named diocletian. hope this you! : )
