Teach students about the late Roman Emperors: Commodus, Diocletian, Maximian, and Constantine. Explain how the Roman Empire was split and discuss the persecution of Christians during this time. Show students a map of Byzantium and explain how Constantinople relocated the capital from Rome to Constantinople. Students then practice locating these places on a map and completing the timeline. After this, discuss the polytheistic ancient Roman religion and have students identify the main gods like Juno, Jupiter, Venus, Mars, Apollo, and Mercury. Finally, show students some of the possible causes for the fall of the Roman Empire including overexpansion and invasions.
