christianity and fall of Rome

in 476 Rome had finally fallen the last emporer was 14 years old and his name was Romulus augustan they liked to call him little disgrace. He was the last bad thing of the Roman Empire before is was completely fallen there was like 5 things that really made it fall and some believe those things are happening now in the us including taxes being to high and division between the people and son other things. We also learned about the rise of christianity and when it really sparked. it sparked when the emperor was married to a Christie but he didn't believe, he was going into battle for the place as emperor and he had a vision before he went. The vision consisted of a cross in the sky and it was also spelling out Christ is greek letters above the cross. He believed God had helped him win the battle so he designated to the Christian God. Most historians actually think it was just this thing called like sun dog or something that occurs every one in a while when the sun and moister and everything is just right. It makes the sky look like a lighten up cross when its actually just the sun in the sky.
