Answer:
#1) Invasions by Barbarian tribes. The most straightforward theory for Western Rome's collapse pins the fall on a string of military losses sustained against outside forces. Rome had tangled with Germanic tribes for centuries, but by the 300s “barbarian” groups like the Goths had encroached beyond the Empire's borders.#2 )One of the many factors that contributed to the fall of the Roman Empire was the rise of a new religion, Christianity. The Christian religion, which was monotheistic ran counter to the traditional Roman religion, which was polytheistic (many gods). Finally, by this time, Romans considered their emperor a god. #3)Christians believe in one God that created heaven, earth, and the universe. The belief in one God originated with the Jewish religion. Christians believe Jesus is the “Messiah” or savior of the world. They also believe that he is the son of God.
