You may know every word of the musical Hamilton. But how much do you know about the real historical figure behind it?

The documentary Hamilton’s America promises to teach viewers about Alexander Hamilton as well as the story of Lin-Manuel Miranda’s musical. In a video interview released today, Lin-Manuel Miranda says he wants Hamilton fans to know the real Alexander Hamilton’s story. “This is a great way of seeing how Hamilton meets the world,” he says in the video. “Hamilton was a real person, and the founding of our country is an incredible story.”

Adds Daveed Diggs: “I really hope that viewers watching this learn a lot of history, and that helps them feel closer to Hamilton our musical.”

The video also offers a peek at footage from the documentary, including a moment when Miranda and Leslie Odom Jr. pose beside dueling statues of Hamilton and Aaron Burr to reenact their deadly encounter.

The PBS documentary airs on Oct. 21 at 9 p.m. ET.
