The Islamic Golden Age – Dr. Roy Casagranda | Museum of the Future: Lessons from the Past

Video Overview & Insights

The Islamic Golden Age is Dr. Roy's seventh lecture for the Museum of the Future's Lessons from the Past (2025). This collaboration between the Museum of the Future and Dr. Roy aims to explore 10 topics ranging from the life of the father of modern medicine to examples of great leadership to the birth of the Most Serene Republic of Venice.

India, persian, turkic and arab countries interacted for millennia. Indo Arabic numerals came about that way

Why did the Islamic Golden Age happen — and why did knowledge not only survive but thrive? In this lecture, Dr. Roy Casagranda shows how ideas passed from Egypt, Mesopotamia, Greece, Rome, and Persia into the Arab empires, where they were protected, studied, and expanded. Unlike civilizations that allowed libraries to burn and wisdom to fade, the Abbasid world cultivated learning as a foundation of power and progress.

Through compelling stories, Dr. Roy explains how scholars like Ibn al-Haytham and Ibn Sina advanced science and medicine, while the preservation of Plato and Aristotle ensured that ancient wisdom lived on to inspire the European Renaissance. This is a history of how cultures that valued knowledge carried it forward — and how that appreciation shaped the course of civilization.

Can someone drop a link of the first video of Dr. Roy on Islamic golden age that he mentioned in the beginning of this video?

Dr. I respect your opinion but is it possible to say Islam was not a part of the reasons for the golden age when learning is a part of the Islamic culture. It's true it may have dropped off but the Qur'an utilises a lot of what may be considered Socratic dialogue and starts many conversations and encourages curiosity in people. It criticises those who don't think for themselves. Early on also, literacy improved greatly in the muslim lands in order to spread the Qur'an, Hadith, Arabic, Grammar etc. Naturally these may have passed through trends and certain topics may have been more popular at different times. Perhaps the focus simply shifted from traditional sciences etc and was interrupted by the lack of peace?
Early on the Muslims showed great tolerance to different traditions such as Jews and Christians which naturally translated to tolerance and engagement with intellectual traditions. Arguably this is part of the natural Muslim culture.
And just as Shahpur was necessary for Muslims to come into contact with texts, perhaps the Muslims were also necessary for Shahpur's legacy to remain intact?

00:13:16 Rome’s Decline & Persian Ascendancy

More people from the Islamic Golden Age should be talked about — like Al Khwarizmi, Ibn Sina, Ibn Al-Haytham and others. 


The contributions they made to society — and how humanity may still be benefiting from them today — is honestly mind blowing.


People need to know more about real Islamic history, because it can encourage us to return to knowledge, discipline, and beneficial learning. The flourishing of Muslim civilisation was deeply connected to Islam’s emphasis on knowledge and strong attachment to the Qur’an and Sunnah.


It’s amazing to think that even the word “algorithm” comes from Al-Khwarizmi, yet many people barely hear about him today.


If we want honour again, then we should reconnect ourselves to the teachings of the Qur’an and the authentic Sunnah of Prophet Muhammad ﷺ while also pursuing beneficial worldly education and knowledge. By the permission of Allah, that combination can help bring strength and honour back to the Ummah.


May Allah Azzawajal grant us beneficial knowledge, sincerity, and righteous action. Allahumma Ameen.

00:23:39 Fall of the Great Library of Alexandria

When I moved 18 years ago to Granada, Andalucia, I was astounded to learn that this European country had been ruled by Muslims for 800 years, and that my Dutch education had failed to teach me anything about it, while simultaneously feeding me Zionism in a secular school. That said a lot about the bias of the west. I'm so grateful to Dr Roy to fill in the many gaps. Thank you, Dr Roy.

Dr. Casagranda: thank you very much for your education of the public. I love your videos. However, I’m a bit puzzled about your lack of mentioning of the Medes, today’s Kurds in the Caucasus and Anatolia. Kurds/Medes created the Persian empire and ruled it for a very long time in. This was done by king Diokes (Diako) descendents. Furthermore, the Sassanids were Kurds and only spoke Kurdish. The same is true for Achaemenids. Kurds have their history stolen by Turks and Persians since the building of nation states and centralised instructions around them started in the 19th century. They are 60 million people, more than Persians and Turks. Yet. They have lived in northern Mesopotamia, Anatolia and the Caucasus for thousands of years. Yet, they are treated as non existent humans by historians like yourself. I would be grateful if you could be kind to take a look at this unfortunate error very much fuels and sponsored by Iran and Turkey for political and nationalistic reasons. Thank you in advance.

I see you are very careful about how Egypt was already GREAT before the Arab invasion. You are very political,the original Egyptians are dark skinned people around the Nile and they are trying to drive them away from the Nile. History can never be rewritten,you are too political.

@KasaliOlalekan
@

Although i may disagree with the way you insert personal modern politics into history, you do an excellent job of conveying that history and making it clear when you are adding your personal take on whatever historical situation. Better than all the "AI" trash and your Arabic pronounciation is excellent in most cases.

@EricHusayn420
@

Well he got one thing wrong.

Islam has to do with the fact that Arabs did not destroy the libraries in Persia.

Their attitude towards other people is the result of our Creed and Shari'a laws.

The greatest proof of that is that the entire Empire doesn't exist long time ago but Islam is still there.

What you've just said is one of the most insanely idiotic things I have ever heard. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone who clicked on this video is now dumber for having listened to it. I award you no points, and may God have mercy on your soul.

5:49 Why the pasta-noodle thing nobody knows where they came from leave it for future generations to figure out

@Demcatszzzzs
@

Before Islam the Arab tribes were mostly fighting interminible blood feuds. There was no way there could ever be an Arab state. Islam brougt them together under the Prophet Muhammad (s), who taught that we are all one family, that love, tolerance, knowledge and humility were essential; that forgiveness was better than revenge. When the Muslims went out to fight they didn't refer to themselves as Arabs, Abu Bakr (r) and Umar (r) didn't send Arab armies, they sent Muslim armies. They referred to themselves as Muslim. If they refer to themselves as Muslim, why call them Arab? It wasn't their arabness that lead to their cohesion or success....it's a kind of nationalism seeping in that wasn't the motivation for the initial conquests. The teachings of Islam, to which the majority adhered, were what guided their decisions. Of course tribal, personal and political motivations didn't just disappear, and this was far more the background of the first fitnah, than the historical warring between Romans and Persians.

There is no such thing as an Islamic golden age - modern historians need to stop preaching and start presenting facts again. But the pasta being imported from China is enough myth and bs for me to just stop - this is not a lecture, it's prop and misinformation.

Dr. Roy asks why Shapur II was called 'The Great' (a later historiographical label by Roman, Syriac and Islamic historians) and not his father Shapur I? It's because historians felt Shapur II earned the title by longevity, recovery and results. Don't get them wrong, Shapur I was extraordinary as he defeated three Roman emperors, even capturing the emperor Valerian alive, and expanded Iran's influence in the west. But his gains in Roman territory were not permanent and the empire didn't fully stabilize after his death. His successors ruled short, unstable reigns. Shapur II inherited a collapsing empire and this is crucial to understand why he is called the great one. He was crowned before birth and inherited Arab raids in the south, Roman pressure in west, nomadic threats in east and weak central authority. Many empires would not recover from these conditions. But he reigned for 70 years (longest sassanian reign), allowed institutional continuity, trained multiple generations of administrators and generals and created longer-term stability. Longevity matters in imperial history. Shapur II reclaimed Mesopotamia, took Amida (359) which was a major Roman catastrophe and forced Rome into favorable treaties (363, after Julian's death). As a result, the borders of Iran stabilized on more favorable terms for decades. He also defeated southern Arab tribes, built defensive lines and fortifications and ended large scale Arab raids into Iran. This secured Mesopotamia, Fars and Khuzestan. He also reasserted control in the East by defeating Chionites/Huns, secured Sogdiana and Tokharistan, and reestablished sassanid authority deep into central asia. This restored Archaemenid-like reach, something Shapur I never achieved. He also standardized Zoroastrian orthodoxy, strengthened clergy state alliance and integrated religious law into governance which led to ideological unity and increased state durability. In short, he saved an empire from collapse, left it stronger than they found it and shaped it for generations. Shapur I is often ranked higher because of the Roman humiliation, Valerian's capture and monumental art (in Kermanshah province, the Naqsh-e-Rostam and Taq-e-Bostan).

Islamic golden age is the biggest lie ever told. Islam never created anything positive, it was only those nations that already had science and philosophy after the Islamic grip was loose, they were able to create advance science and nearly ALL of those scientists were labeled as infidels and persecuted acct to Islamic principles.

Correction*. Islam is not a new religion

@deanblack4957

I respect Dr Roy Casagranda but saying there is no religious component to the Abbasid Golden Age is too much of an orientalist take for me (11:29).

Furthermore, who defines the 'Islamic Golden Age' and is it only tied to worldly advancement?

For Muslims, the 'Islamic Golden Age' would be defined by the period of the Noble Messenger Muhammad ﷺ and his Companions (Allah be pleased with them).

The Spanish did not pull or raze anything to the ground. Mayan and Aztec temples and pyramids were left alone and intact. Templo Mayor and Chichén Itzá’s El Castillo, for example, are frequent tourist attraction and proof the Spanish were never brutes and lowbrow barbarians razing conquered cities to the ground. If that were the case, if the Spanish were inherently that barbaric then they would be right now all in helping the anglo-saxon zionists commit their genocide in Palestine. Please stop lumping Spain into the same category of the Germans, British and French when it comes to sacking, pillaging and genocides, respectfully and thank you.

Starting at 42:39, I have a question. Brilliant as the Arab Agricultural Revolution was - how exactly did they figure out "shipping with ice" when all of their port cities ESPECIALLY ones shipping food to India would have been in warm climates?

In other words, we must thank the Persians who have preserved all our knowledge for us, and in other words, it is not really the Islamic Golden Age, but the Persian Golden Age!?

@siaser123

from 240 surviving books from Ibn Sina, only two are in Persian, so how do you claim he wrote frequently in Persian 😅

Persian was never a dominant language for science but for literature 😅

Khwarezmi was not Persian, he was actually Turkic from Uzbekistan

Gondiee shahpour in Kurdish means city of shahpour ... because sassanides were a Kurdish tribe like all other Iranian dynasties before islam.
Maybe you could do a video about Kurds and prov that all Iranians before Arab invasion and ultimately Saljuc Turks did not speak Farsi in Iran.
You can prove all that genetically and linguisticly.
Farsi started in Tajikistan and Afganîstan ( Greater Khorasan). 😊
