Constantine and the Legalization of Christianity

In this lesson, you’ll explore one of the most important turning points in Roman history: when Emperor Constantine changed the future of Christianity forever. For hundreds of years, Christians had been punished for their beliefs. But after a powerful vision before battle, Constantine made a bold decision that would impact the empire and the world.

As you read, pay attention to these key questions:

  • Who was Constantine, and what happened before the Battle of the Milvian Bridge?

  • What was the Edict of Milan, and how did it change the lives of Christians?

  • Why was the legalization of Christianity such a big deal for Roman society?

By the end of this lesson, you’ll understand how one emperor’s choice helped Christianity grow from a hidden faith into a powerful force in the Roman Empire and beyond.

Talk Show Script Planner Introduction

In this activity, you’ll step into the shoes of people living during one of the most important turning points in Roman history: the moment when Emperor Constantine legalized Christianity. You and your group will create a talk show panel where each person represents a different point of view from that time.

Your job is to work together to plan what your characters will say, using facts and ideas from Lesson 2: Constantine and the Legalization of Christianity. You’ll explore how this big decision affected different people and explain why it was such a major change for the Roman Empire. Use this planner to organize your questions, script your answers, and get ready to bring history to life!
