The Ottoman Empire, one of history’s most powerful and long-lasting empires, is often remembered for its military might and territorial expansion. However, one of its most remarkable aspects was its approach to religious diversity. The Ottomans, as Muslims, considered Jews and Christians as “People of the Book,” recognizing their shared Abrahamic roots. This recognition led to a unique system of religious coexistence that lasted for centuries and left a lasting impact on the regions under Ottoman rule.
The People of the Book
The concept of “People of the Book” (Ahl al-Kitab in Arabic) is rooted in Islamic theology. It refers to followers of monotheistic religions that predate Islam, primarily Jews and Christians. The Quran acknowledges these faiths as having received divine revelation through their prophets and scriptures.
As an Islamic state, the Ottoman Empire adopted this concept and applied it to its governance, allowing for a level of religious tolerance that was uncommon in many other parts of the world at the time.
The Millet System
The Ottoman Empire had a special way of dealing with different religious groups, which they called the “Millet System.” It was like having mini-communities within the big empire. Each religious group that the Ottomans recognized was called a “millet.”
These millets had a lot of freedom to run their own affairs. It’s like they had their own little governments within the empire. They could make decisions about family matters and personal issues using their own religious laws. For example, if there were a dispute about a marriage or inheritance, they would solve it their own way.
The millets also had some other important jobs. They collected taxes from their own people and gave them to the Ottoman government. They took care of their churches, synagogues, or other religious buildings. They even ran their own schools, teaching their children about their faith and culture.
Now, it wasn’t all perfect. Non-Muslims had some rules they had to follow, including paying a special tax called “jizya.” But even with these rules, they could still practice their religion freely, wear their traditional clothes, speak their own languages, and keep their cultural traditions alive.
The Millet System system helped different religious groups live side by side in the Ottoman Empire for many years. It wasn’t exactly equal to how Muslims were treated, but for its time, it was quite tolerant compared to many other places in the world.
The Patriarchate of Constantinople
One of the most striking examples of Ottoman religious tolerance was their treatment of the Ecumenical Patriarchate of Constantinople, the spiritual leader of Eastern Orthodox Christianity. When Sultan Mehmed II conquered Constantinople in 1453, he allowed the Patriarchate to continue functioning.
In fact, Mehmed II went a step further. He not only preserved the existing Greek Orthodox Patriarchate but also established the Armenian Patriarchate of Constantinople in 1461, which was particularly significant because the Byzantines, who ruled before the Ottomans, had considered the Armenian Church heretical and did not allow it to operate within Constantinople’s walls.
The Patriarchate’s continued presence in Istanbul (formerly Constantinople) to this day is a testament to this policy of religious tolerance. It remains one of the fourteen autocephalous Eastern Orthodox churches and is considered “first among equals” in the Eastern Orthodox communion.
Atheism: A Modern Concept
While the Ottoman Empire showed remarkable tolerance towards different faiths, the concept of atheism as we understand it today was largely absent. In the Ottoman worldview, and indeed in much of the world until the 19th century, the existence of God was considered self-evident.
The idea that someone might not believe in any god at all was so foreign that such a person might be considered insane rather than heretical, a perspective that wasn’t unique to the Ottoman Empire but was common across Europe and the Near East.
In Turkey, the modern successor state to the Ottoman Empire, atheism remained extremely rare until quite recently. Even as late as two decades ago, the number of self-proclaimed atheists in Turkey was negligible, which cannot be attributed solely to social pressure, as Turkey has had many openly atheist writers and artists, some of whom are considered national treasures.
However, times are changing. Today, atheists make up about 3% of the Turkish population, with many more having left organized religion without necessarily identifying as atheists.
The Historical View of God’s Existence
Until the 19th century, the prevailing wisdom in Europe and the Near East was that our very existence was irrefutable proof of God’s existence. In this worldview, saying “there is no God” was considered as irrational as saying “I don’t exist.”
This perspective helps explain why atheism, as we understand it today, was such a foreign concept in the Ottoman Empire and other societies of the time. The idea that the universe could exist without a divine creator was simply not part of the intellectual landscape.
Legacy and Modern Implications
The Ottoman approach to religious diversity left a lasting impact on the regions it once ruled. Many Balkan and Middle Eastern countries still have diverse religious populations, a legacy of the empire’s policies.
However, it’s important to note that while the Ottoman system was progressive for its time, it wasn’t perfect by modern standards. Non-Muslims still faced certain restrictions and were not considered fully equal to Muslims under the law.
Today, Turkey, as the successor state to the Ottoman Empire, continues to grapple with issues of religious freedom and secularism. While its constitution provides for freedom of religion, and Turkey is a party to the European Convention on Human Rights, there have been concerns about religious freedom violations, particularly for some non-Muslim citizens.
The Takeaway
The Ottoman Empire’s approach to religious diversity, rooted in the Islamic concept of “People of the Book,” created a remarkable system of coexistence. The continued presence of the Ecumenical Patriarchate in Istanbul stands as the living legacy of the Ottoman Empire.
While the challenges we face today differ, the Ottoman example reminds us that diversity and faith can coexist, even in the most powerful empires.
