Transcript of The 1,000-year Legacy of Ibn Sina: Dr. Roy Casagranda

Read the full transcript of historian Dr. Roy Casagranda’s lecture titled “The 1,000-year Legacy of Ibn Sina” for the Museum of the Future’s Lessons from the Past (2025).

Setting the Historical Stage

DR. ROY CASAGRANDA: So the topic tonight is Ibn Sina. And the reason why I wanted to start with Ibn Sina is he wrote his opus magnum, the Canon of Medicine in 1025. So this is the one thousandth anniversary year for that book. And I just felt like we have to start there. To do this though, I have to give you a background.

I can’t just throw you in and then you figure it out. So let’s start with the background. The time period that Ibn Sina lived in is a turbulent time period. There’s enormous political upheaval because the Middle East is actually reshaping itself. But to understand that, I need to put the clock back a little bit.

In 632, the prophet Muhammad dies and when he dies, he’s replaced by Khalifa Abu Bakr. He becomes the leader of what will become the Arab Empire. In 632, his biggest problem is he has to put down the apostates that have popped up and that becomes the Ridda wars. It takes about a year. So by 633, he’s done it.

The amazing thing about that is it means that in 633, for the first time in history, there is a single state that ruled the entire Arabian Peninsula that had never happened before. The Arabian Peninsula parts of it had been conquered, but it had never been conquered as a single entity by anybody. The Romans had the northwest corner, the Persians the northeast corner, and by the way, the southeast corner. At one point, they even grabbed Yemen so they even had the southwest corner, but nobody had ever conquered the whole as a single state.

The Rise of the Arab Empire

The shocking and incredible thing that happens next is Abu Bakr sends a letter to his general Khaled ibn Al Walid who was in Yamama at the time and said, don’t stop.
