Türkiye

From Neolithic Çatalhöyük and the Hittites through Byzantium and the Ottomans to Atatürk's republic.

The land of modern Türkiye carries one of the world's deepest human pasts: the Neolithic town of Çatalhöyük, the Bronze Age Hittite empire centred on Hattusa, and the legendary city of Troy. Greek, Roman and then Byzantine Anatolia made Constantinople a Christian imperial capital for a thousand years, until the Seljuk victory at Manzikert (1071) opened the peninsula to Turkic settlement. From a frontier principality founded around 1299, the Ottoman dynasty rose to take Constantinople in 1453 and to rule a vast empire that peaked under Süleyman the Magnificent. The empire's long decline ended in the catastrophe of the First World War, the Armenian Genocide of 1915–16, and partition — out of which Mustafa Kemal Atatürk forged a national movement that won the War of Independence and proclaimed the Republic of Turkey on 29 October 1923.

Proclamation of the Republic of Turkey

29 October 1923

Modern Türkiye dates its political founding to 29 October 1923, when the Grand National Assembly in Ankara proclaimed the Republic of Turkey and elected Mustafa Kemal — later surnamed Atatürk, 'Father of the Turks' — as its first president. The republic rose on an Anatolian land of extraordinary depth: the Neolithic settlement of Çatalhöyük (occupied c. 7100–5700 BCE), the Hittite empire at Hattusa, and the city of Troy of Homer's Iliad. Greek and Roman Anatolia gave way to Byzantine Constantinople, the Christian imperial capital refounded by Constantine in 330 CE. After the Seljuk Turks broke Byzantine power at Manzikert in 1071, a frontier emirate founded around 1299 by Osman I grew into the Ottoman Empire, which took Constantinople in 1453 and endured until its collapse after the First World War.

Ancient Anatolia: Çatalhöyük, the Hittites and Troy

Anatolia holds some of humanity's earliest towns and one of the great Bronze Age empires, alongside the city immortalised by Homer.

Few landscapes preserve as deep a human record as Anatolia. On the Konya plain, the Neolithic settlement of Çatalhöyük was inhabited for some 1,400 years, roughly between 7100 and 5700 BCE. Its densely packed mudbrick houses, entered through the roof, and its wall paintings, reliefs and figurines document the transition from village life to a proto-urban world; the site was inscribed by UNESCO as a World Heritage Site in 2012.

In the Bronze Age, central Anatolia became the heartland of the Hittites, an Indo-European people who built an empire from their capital Hattusa (near modern Boğazkale). Hattusilis I made Hattusa his seat in the 17th century BCE, and under rulers such as Suppiluliuma I the Hittites rivalled Egypt, clashing with the pharaohs at the Battle of Kadesh and producing some of the earliest known international treaties.

On the Aegean coast at the mound of Hisarlık stood Troy, the city of Homer's Iliad. Excavations begun by Heinrich Schliemann in 1870 revealed not one city but a sequence of settlements spanning some four thousand years; the level known as Troy VI–VII is the likeliest candidate for the Troy of legend. The Hittite world and the wider eastern Mediterranean were swept away around 1200 BCE in the Bronze Age collapse.

Chapter 02 · c. 1180 BCE – 1071 CE

Greek, Roman and Byzantine Anatolia

Greek colonists, then Roman and Byzantine emperors, made Anatolia a Hellenic and Christian heartland centred on Constantinople.

After the Bronze Age collapse, Greek settlers colonised the Aegean coast, founding cities such as Ephesus, Miletus and Smyrna, while inland kingdoms — Phrygia, Lydia and others — rose and fell. Lydia, under kings like Croesus, is credited with minting some of the world's first coins. The region passed under Persian rule before Alexander the Great's conquests spread Hellenistic culture across Anatolia in the late 4th century BCE.

Rome absorbed Anatolia from the 2nd century BCE, and the peninsula — 'Asia Minor' — became one of the wealthiest, most urbanised parts of the empire. It was also a cradle of early Christianity: Paul of Tarsus was an Anatolian, the seven churches of Revelation lay in the west, and the great ecumenical councils of Nicaea (325) and Chalcedon (451) met on Anatolian soil.

In 330 CE Constantine the Great refounded the Greek town of Byzantium as Constantinople, a 'New Rome' guarding the Bosporus. As the western empire fell, the Greek-speaking Christian state of the eastern Romans — the Byzantine Empire — endured for over a thousand years, reaching a high point under Justinian I, who built the Hagia Sophia in the 530s. Repeated wars with Persians and Arabs strained the empire, and in 1071 the Seljuk Turks shattered the Byzantine army at Manzikert, opening Anatolia to Turkic settlement.

Constantine dedicated his 'New Rome' on the Bosporus in 330, anchoring a Christian empire that would last more than a thousand years.

Chapter 03 · 1071 – 1453

The Rise of the Seljuks and Ottomans

Turkic peoples settled Anatolia, and from a small frontier emirate the Ottoman dynasty rose to take Constantinople.

In the wake of Manzikert, Turkic tribes spread across Anatolia. The Seljuks of Rûm established a sultanate centred on Konya, presiding over a flourishing of Islamic art, architecture and learning — the era of the poet and mystic Rumi. The Mongol invasions of the 13th century fragmented Seljuk power into a patchwork of Turkish principalities, or beyliks, competing on the Byzantine frontier.

Out of one such frontier emirate in north-western Anatolia rose the Ottomans. Tradition dates the dynasty's foundation to around 1299, under Osman I, whose name the dynasty bears. His successors expanded rapidly: Bursa fell in 1326 and became an early capital, and by crossing into Europe the Ottomans took Adrianople (Edirne) and won the Battle of Kosovo in 1389, encircling a shrinking Byzantium.

A shattering setback came in 1402, when the conqueror Timur (Tamerlane) defeated and captured Sultan Bayezid I at the Battle of Ankara, throwing the empire into a civil war known as the Interregnum. The dynasty recovered, and in 1453 the young sultan Mehmed II besieged and stormed Constantinople, ending the Byzantine Empire and making the city — increasingly called Istanbul — the Ottoman capital.

After a 53-day siege the Byzantine Empire — nearly 1,500 years of Roman continuity — came to an end at Constantinople in 1453.

Chapter 04 · 1453 – 1914

The Ottoman Empire: Height and Decline

Under Süleyman the Magnificent the empire reached its zenith, before centuries of contraction earned it the name 'the sick man of Europe'.

The 16th century was the Ottoman golden age. Süleyman I, called 'the Magnificent' in Europe and 'the Lawgiver' (Kanuni) at home, reigned from 1520 to 1566 over an empire spanning the Middle East, North Africa and south-eastern Europe. His armies took Belgrade and Rhodes, won at Mohács in 1526, and besieged Vienna in 1529; his court patronised a flourishing of architecture under the master builder Sinan and codified Ottoman law.

The empire remained a great power into the 17th century, but its second siege of Vienna in 1683 failed, and the Treaty of Karlowitz in 1699 forced major territorial losses for the first time. Over the following centuries the Ottomans steadily lost ground to Russia, Austria and rising nationalist movements in the Balkans, while struggling to reform their military and administration.

Reform efforts known as the Tanzimat (from 1839) sought to modernise law, the army and the state, and a short-lived constitution was granted in 1876. In 1908 the Young Turk Revolution restored constitutional rule, but successive wars — in Libya, the Balkans and beyond — stripped away most remaining European and African territories. By 1914 the much-diminished empire, often called 'the sick man of Europe', stood on the brink of a final, catastrophic war.

Süleyman the Magnificent ruled an empire of some 25 million people, from the gates of Vienna to the deserts of Arabia.

Chapter 05 · 1914 – 1923

World War I, the Armenian Genocide and the War of Independence

The empire's entry into the First World War brought the Armenian Genocide, defeat and partition — and then a national resistance that forged the republic.

The Ottoman Empire entered the First World War in late 1914 on the side of Germany and Austria-Hungary. Its forces repelled the Allied landings at Gallipoli in 1915–16, where a young officer named Mustafa Kemal distinguished himself, but the war elsewhere went badly, with defeats in the Caucasus, Mesopotamia and the Arab provinces.

Against this backdrop, in 1915–16 the ruling Committee of Union and Progress carried out the systematic deportation and mass killing of the empire's Armenian population. Beginning with the arrest of Armenian leaders in Constantinople on 24 April 1915, the regime drove Armenians on death marches into the Syrian desert amid massacres, starvation and exposure. Most historians regard these events as genocide — the first genocide of the 20th century — with estimates of the dead generally ranging from around 600,000 to as many as 1.5 million.

Ottoman defeat in 1918 was followed by Allied occupation and the punitive Treaty of Sèvres (1920), which would have dismembered Anatolia. Rejecting the treaty, Mustafa Kemal organised a nationalist resistance and a rival Grand National Assembly in Ankara in 1920. The ensuing War of Independence (1919–1922) defeated Greek, Armenian and French forces and expelled the occupiers.

Victory was sealed by the Treaty of Lausanne on 24 July 1923, which recognised the sovereignty of the new Turkish state within roughly its modern borders. The sultanate had already been abolished in November 1922, ending more than six centuries of Ottoman rule and clearing the way for a republic.

Most historians have concluded that the deportations and massacres of 1915–16 meet the definition of genocide — the intentional destruction of an ethnic or religious group.

The Republic and Modern Türkiye

Atatürk's secular republic modernised radically, moved to multiparty democracy, joined NATO, and became a pivotal regional power.

On 29 October 1923 the Grand National Assembly proclaimed the Republic of Turkey and elected Mustafa Kemal its first president. Over the following years Atatürk drove a sweeping programme of reform: the caliphate was abolished in 1924, religion was separated from the state, the legal system was secularised on European models, the Latin alphabet replaced the Arabic script in 1928, and women gained the vote in national elections by 1934. Ankara became the capital in place of Istanbul.

Atatürk died in 1938 and was succeeded by İsmet İnönü. After the Second World War, in which Turkey remained largely neutral, the country moved to multiparty politics: the 1950 election brought the opposition Democrat Party to power in the first peaceful transfer of government. Turkey joined NATO in 1952, anchoring it firmly in the Western alliance during the Cold War, though its politics were repeatedly interrupted by military coups in 1960, 1971 and 1980.

Turkey was recognised as a candidate for European Union membership in 1999, and the early 2000s brought rapid economic growth under Recep Tayyip Erdoğan and the AK Party. Constitutional changes approved by referendum in 2017 and enacted in 2018 transformed the parliamentary system into a powerful executive presidency. In June 2022 the country registered its official name at the United Nations as 'Türkiye'.

Modern Türkiye is a populous, strategically pivotal state bridging Europe and Asia, a member of NATO and the G20, custodian of an extraordinary archaeological heritage, and a country still debating the balance between secular and religious identity that has run through its republican century.

In a single republican generation, Türkiye abolished the caliphate, adopted the Latin alphabet, enfranchised women and reoriented itself toward Europe.
