the emperor constantine is significant because
a) he brought the roman republic to an end.
b) the romans fell to the ottomans during this reign.
c) he was the first roman emperor to convert to christianity.
d) the empire of alexander the great was conquered during his rule.

hello! the answer B is incorrect! the correct answer is  C: He was the first Roman Emperor to convert to Christianity!

either b) they were often feared and despised by other native cultures. or

c) their obsession allowed them to coexist with many other native cultures because of their peaceful nature.

when people started to question traditional christian beliefs, they became criminals in the eyes of the church: they were accused of heresy and then, executed. the church held unbelievable power and anyone who tried to defy it or its beliefs, was demonized and persecuted.

mark brainliest and have a stunning day!
