The Ottoman Empire’s Legacy in Modern Türkiye

Article Summary

What this article covers: How the Ottoman Empire shaped modern Türkiye’s architecture, religious life, law, food and language, with the sites and neighbourhoods where travellers can see that legacy in person.

Who this is for: Travellers planning a first trip to Türkiye, culture enthusiasts who want the history behind Istanbul’s skyline, and readers researching what the Ottoman Empire actually left behind.

Key takeaway: The Ottoman Empire ended in 1922, but its mosque complexes, coffee houses, food, administrative habits and place names are still the framework of daily life in Türkiye, which makes the country readable in a way few destinations are.

Expert insight: “I climbed to the Süleymaniye terrace on a February afternoon when the muezzins across the Golden Horn all started within a few seconds of one another, and the sound arrived from about six directions at once. Standing there you understand that the Ottomans were not just building mosques, they were laying out the acoustics and sightlines of a whole city. That is the thing I keep coming back to when we film in Istanbul.” , Ciaran Connolly, Founder of ConnollyCove

Quick facts:

• The Ottoman Empire lasted from roughly 1299 to 1922, when the sultanate was abolished; the Republic of Türkiye was proclaimed on 29 October 1923
• Bursa and Cumalıkızık were inscribed on the UNESCO World Heritage List in 2014 under the title “Bursa and Cumalıkızık: the Birth of the Ottoman Empire”
• Turkish coffee culture, a habit that spread from Istanbul’s sixteenth-century coffee houses, was added to UNESCO’s Intangible Cultural Heritage list in 2013

Stand in the courtyard of the Süleymaniye Mosque in Istanbul and you are standing in a piece of civic infrastructure, not just a place of worship. The mosque came with a medical school, a hospital, a primary school, a public bath and a kitchen that fed the poor. That bundling of religion, welfare and education into one walled compound is the clearest single thing the Ottoman Empire handed to modern Türkiye, and once you can recognise it you start seeing it in every Turkish city you visit.

Türkiye is unusually legible for travellers because so much of the imperial fabric is still standing and still in use. The mosques hold prayers, the bazaars sell things, the hammams take bookings. This guide covers what the Ottoman Empire actually left behind, how much of it survived Atatürk’s republican reforms, and where you can go to see each piece of it. ConnollyCove covers cultural heritage across Ireland and worldwide, and Türkiye is one of the places where the gap between a history book and a walk through a neighbourhood is smallest. If you are building a wider itinerary, our guide to visiting Türkiye sets out the practical route options.

What Did The Ottoman Empire Leave Behind?

Three inheritances dominate: the built environment, the religious and communal habits of Turkish public life, and the administrative reflexes of the state. Everything else, the food, the vocabulary, the music, the coffee, sits downstream of those three. The Ottoman Empire ran for roughly six centuries from a small Anatolian principality to a state spanning three continents, and it did not so much vanish in 1922 as get reorganised into a republic that kept the plumbing and changed the plaque.

The Six Centuries in Brief

Osman I founded the beylik that carried his name in north-western Anatolia around 1299. His son Orhan took Bursa in 1326 and made it the capital, and The Ottoman Empire pushed westwards from there into Thrace and the Balkans. Constantinople fell in 1453 to Sultan Mehmed II, which ended the Byzantine Empire and gave the Ottomans a capital positioned between Europe and Asia. The sixteenth century under Selim I and Süleyman I was the territorial peak, with the empire holding the Balkans, Anatolia, the Levant, Egypt, much of North Africa and the Hijaz.

Decline was slow and uneven rather than sudden. The nineteenth-century Tanzimat reforms restructured law, taxation and provincial government while the empire lost territory in the Balkans and the Caucasus. Defeat in the First World War as an ally of Germany and Austria-Hungary ended it. The Treaty of Sèvres in 1920 would have dismembered what remained; it was never ratified, and the Turkish War of Independence produced the Treaty of Lausanne in 1923 instead.

From Empire to Republic

The break was sharper than the continuity, which is worth saying plainly because a lot of writing on this topic pretends the republic simply carried on. Mustafa Kemal Atatürk’s government abolished the sultanate in November 1922, proclaimed the Republic of Türkiye in October 1923, and abolished the caliphate in March 1924. Its official name is the Republic of Türkiye. Over the following decade it replaced Ottoman legal codes with adapted European ones, switched from Arabic to Latin script in 1928, and closed the Sufi lodges.

What survived was structural rather than symbolic. A centralised bureaucracy answerable to the capital, a provincial governor system with recognisably Ottoman shape, state management of religious endowments, and a habit of treating the state as the author of national culture. Those are patterns inherited from The Ottoman Empire, wearing republican clothes.

How The Ottoman Empire Shaped Türkiye’s Cities and Architecture

Ottoman city-building worked outwards from the külliye, a walled complex built around a mosque and funded by a charitable endowment called a vakıf. Neighbourhoods grew around these complexes rather than the other way round, which is why the historic cores of Bursa, Edirne and Istanbul read as clusters of institutions with housing filling the gaps. This is the most visible part of the legacy of The Ottoman Empire and the easiest for a visitor to go and look at.

Mimar Sinan and the Imperial Mosque

Sinan served as chief imperial architect from 1538 until his death in 1588 and is credited with hundreds of buildings across the empire. His work solved a specific problem: how to roof a very large open room with a single dome and make the structure look weightless from outside. The Şehzade Mosque, the Süleymaniye and the Selimiye at Edirne are the sequence people usually cite, and Sinan himself regarded the Selimiye as his best. If you visit only one, make it Edirne rather than Istanbul, because the Selimiye stands more or less alone and you can read the whole geometry at once.

Students of Sinan carried the vocabulary to Mecca, Damascus, Sofia and Budapest, which is why Ottoman mosques in Istanbul and Ottoman mosques in the Balkans share a silhouette. Half-domes stepping down from a central dome, a colonnaded forecourt with a fountain, slim pencil minarets: the grammar is consistent enough that you can date buildings by eye after a few days.

The Külliye as Town Planning

A külliye typically contained a mosque, a madrasa, an imaret serving free meals, a hammam, a hospital or medical school, a library and the founder’s tomb. The vakıf endowment that funded it was often a village, a market building or a bath whose income was assigned in perpetuity. This was the welfare system, and it was privately founded but publicly available. Modern Turkish ministries that manage religious foundations are the direct administrative descendants of that arrangement.

Bursa shows the model at its earliest. UNESCO inscribed Bursa and Cumalıkızık in 2014 precisely because the eight component sites, five sultanic complexes plus the khans district and a surviving vakıf village, illustrate the whole urban and rural system in one place. Read the official UNESCO inscription for Bursa and Cumalıkızık before you go.

Our Bursa city guide covers the practical side of the visit.

Ottoman Buildings Beyond the Mosque

Bridges, aqueducts, caravanserais, covered markets and fortifications belong to the same programme. The Grand Bazaar in Istanbul began as two masonry warehouses under Mehmed II in the 1450s and grew by accretion into the covered maze it is now. Ottoman military engineering left fortifications along both coasts and the interior, and our guide to castles across Türkiye maps the ones worth a detour.

Even the Bosphorus waterfront reads as an Ottoman composition, with imperial pavilions and waterside mansions placed for the view back at the city.

Was The Ottoman Empire Diverse? Religion, Millets and Cultural Blending

Yes, and the diversity was administered rather than incidental. The Ottoman Empire governed Muslims, Greek Orthodox and Armenian Christians, Jews, Alevis, Yazidis, Druze and others across territory stretching from Bosnia to Basra, and it did so by organising non-Muslim subjects into self-governing religious communities. Understanding that system explains both how the empire held together for so long and why it came apart when nationalism arrived.

The Millet System Explained

Non-Muslim communities were recognised as millets, each led by its own religious hierarchy and each running its own courts for marriage, inheritance, education and internal disputes. The Greek Orthodox Patriarch, the Armenian Patriarch and the Chief Rabbi answered to the sultan and were responsible for their communities’ taxes and good behaviour. In exchange, adult non-Muslim men paid the cizye poll tax and accepted a subordinate legal status, including restrictions on dress, building and testimony in Muslim courts.

Two corrections are worth making, because most summaries get this wrong. First, the millet system was not a single coherent code from the beginning; historians including Benjamin Braude have argued that the tidy “classical millet system” is largely a nineteenth-century reconstruction projected backwards onto messier earlier arrangements. Second, the arrangement was tolerance in the specific sense of permitted difference under a hierarchy, not equality. The 1856 reform edict formally declared subjects equal regardless of religion and abolished the cizye, which was the point at which the older model began to break.

Cultural Achievements of The Ottoman Empire

The cultural output of The Ottoman Empire was synthetic by design, drawing Persian poetic form, Arabic scholarship, Byzantine building practice and Central Asian Turkic tradition into something identifiable as Ottoman. Calligraphy became the prestige art because figural representation was constrained in religious contexts, and Ottoman calligraphers developed scripts still taught today; you can see how that fits into wider traditions in our guide to the art of calligraphy. Ottoman court poetry, the divan tradition, used Persian metres and a heavily Persianate vocabulary. Iznik tilework, with its cobalt and coral palette, went from imperial commission to global export.

Music, textiles, shadow puppetry, paper marbling and miniature painting all developed under court patronage funded by the same vakıf and treasury systems that built the mosques. The Whirling Dervishes of Türkiye are the best-known surviving performance tradition, though the Mevlevi lodges were closed in 1925 and what visitors see today is a revived ceremony rather than an unbroken practice.

What Diversity Cost The Empire

The millet structure worked as long as identity was primarily religious. Once romantic nationalism reached the Balkans in the nineteenth century, communities that had been organised by faith reorganised themselves as nations with territorial claims, and The Ottoman Empire had no mechanism for that. Greek independence, Serbian and Bulgarian autonomy and the Balkan Wars of 1912 to 1913 followed in sequence.

The final decade was catastrophic. The Armenian Genocide of 1915, carried out through deportations, massacres and enforced starvation, destroyed the ancient Armenian communities of eastern Anatolia; Assyrian and Ottoman Greek populations suffered mass killing in the same period. The 1923 population exchange codified at Lausanne then moved well over a million Greek Orthodox Christians out of Anatolia and several hundred thousand Muslims out of Greece. Türkiye continues to reject the legal designation of genocide, while the scholarly and human rights consensus outside Türkiye holds that the 1915 killings were systematic. Any honest account of The Ottoman Empire has to include this, and travellers will meet the disagreement in museum labelling and local conversation.

The Ottoman Empire’s Legacy Beyond Türkiye

Roughly thirty modern states sit on former Ottoman territory, and the administrative decisions of The Ottoman Empire are still legible in their borders, their property records and their vocabulary. This matters to travellers because it explains why a market street in Sarajevo, Skopje or Amman feels structurally like one in Bursa.

The Balkans

Rule by The Ottoman Empire in south-eastern Europe lasted five centuries in places, and it left mosques, bridges, bathhouses and the covered market quarter as an urban form. It also left vocabulary: the Turkish word çarşı, meaning market district, survives as čaršija in Bosnian and Serbian, and hundreds of Turkish loanwords for household objects, foods and trades remain in Balkan languages. Conversion to Islam among Slavic and Albanian populations created communities whose descendants are still there, which is one root of the region’s twentieth-century conflicts. Our guide to Ottoman influence in the Balkans covers this in more depth.

One of the more surprising survivals sits in central Budapest at the Tomb of Gül Baba, the burial place of a sixteenth-century dervish.

The Middle East

The provinces of the empire, the vilayets, were bounded with regard to trade routes, tribal territory and river systems. When British and French administrators drew mandate borders after 1920 they inherited those lines and cut across them, separating ports from the interiors they served. Ottoman land registration under the 1858 Land Code also produced the paper trail that many property claims across the Levant still depend on. Our Middle East destination coverage works through the region country by country.

Food, Coffee and the Shared Table

The kitchens of The Ottoman Empire standardised a repertoire across an enormous area, which is why baklava, stuffed vine leaves, minced meat köfte and yoghurt-based sauces turn up under cognate names from Athens to Aleppo. Coffee reached Istanbul in the mid-sixteenth century and the coffee house followed almost immediately, becoming the empire’s forum for gossip, storytelling, backgammon and political complaint, and getting itself banned more than once as a result. Turkish coffee culture went onto UNESCO’s Intangible Cultural Heritage list in 2013. Our wider piece on global coffee rituals traces where the habit travelled next.

Where to See The Ottoman Empire’s Legacy in Türkiye

Istanbul, Bursa and Edirne form the obvious circuit, and they are close enough to combine in a week. Istanbul gives you the capital of The Ottoman Empire at full scale, Bursa gives you the empire before it had money, and Edirne gives you Sinan at his peak without the crowds. All three are straightforward on public transport.

Istanbul in Two Days

Start on the historic peninsula, which UNESCO inscribed in 1985 as the Historic Areas of Istanbul. Day one covers Hagia Sophia, the Blue Mosque, the Hippodrome and the Topkapı Palace, with the Grand Bazaar as a late afternoon. Day two goes to the Süleymaniye and its terrace, then the Golden Horn and Eyüp.

The Topkapı Palace courtyards reward more time than most people give them, since the sequence of gates and gardens is how the empire staged its own authority.

Our list of things to do in Istanbul fills in the gaps around those anchors.

If you are still deciding whether to go at all, ten reasons to visit Istanbul is the shorter read.

Two practical notes. Mosques close to visitors during the five daily prayers and for longer around Friday midday, so check the times rather than arriving hopefully. Women need a headscarf and everyone needs covered knees and shoulders; most large mosques lend scarves at the door.

Bursa, Edirne and Further Out

Bursa is about two and a half hours from Istanbul by bus and ferry combination and rewards a full day for the Green Mosque, the Muradiye complex and the khans district, with Cumalıkızık village as a short onward hop. Edirne sits near the Greek and Bulgarian borders and is a day trip by bus, with the Selimiye as the reason to go.

Beyond the imperial triangle, quarters built under The Ottoman Empire survive across the country, and Antalya has one behind its harbour.

The wider culture of western Asia puts Türkiye in regional context.

If you have come to Türkiye through television rather than history books, the period dramas were filmed in many of these same buildings, and our guide to Turkish TV series locations matches the screen to the site.

Making Sense of What You See

The Ottoman Empire is worth understanding before a trip to Türkiye because it changes what a mosque courtyard, a covered market or a bathhouse actually is. Each one was a piece of a working system for housing, feeding, treating and educating a city, and most of them are still doing some version of that job. Read the külliye rather than the dome and the country opens up.
