This paper is not about the Battle of Milvian Bridge as a whole, I am researching how it was caused.

foot/endnotes and bibliography
standard one-inch margins
12-point font, Times (New Roman)

There is a document attached and it has some of the beginnings of what I want to do with 2 scholarly articles to start with.
Add more sources as necessary, preferably from JStor.
