Zafer Bayramı (Victory Day): What August 30 Actually Commemorates

From the defeat of the Ottoman Empire to the victory that changed the future of Anatolia

For readers in a hurry: Zafer Bayramı, celebrated every August 30, commemorates the decisive Turkish victory at Dumlupınar in 1922. But understanding why this battle matters requires going back to 1918. The Ottoman Empire had lost the First World War.

Its capital and parts of its remaining territory were occupied, its army was disarmed, and the Treaty of Sèvres proposed a postwar order that would leave much of Anatolia outside Turkish control or under severe foreign influence. The National Struggle led by Mustafa Kemal and his fellow commanders rejected that future. The victory of August 30 broke the Greek army's position in western Anatolia and made a different political settlement possible. İzmir was liberated on September 9, the fighting ended with the Mudanya Armistice, and the Treaty of Lausanne followed in 1923. This is why August 30 is remembered in Türkiye as zafer: victory.

Every year at the end of August, the same word begins appearing across Türkiye: zafer. It hangs from municipal buildings, appears on television, and sits beside photographs of Mustafa Kemal at Kocatepe. Turkish flags become more visible on balconies and streets.

A few days later, another word becomes especially visible in İzmir: kurtuluş, liberation. Then October arrives with cumhuriyet, republic.

These words belong to the same history, but they do not describe the same event. To

understand why August 30 is zafer, the story has to begin with a defeat.

An empire loses a war

The Ottoman Empire entered the First World War in 1914 on the side of the Central Powers. Four years later, that side had lost.

On October 30, 1918, the Ottoman government signed the Armistice of Mudros. The war was over for the empire, but peace had not yet been settled. The Ottoman army was to be demobilized, weapons and ammunition surrendered, and the Allies received broad rights to occupy strategic positions.

The consequences soon became visible.

British, French and Italian forces entered Istanbul. The Allied occupation affected ports, railways and communications as well as military installations. There were foreign soldiers in the capital, censorship and restrictions on movement.

Occupation also spread across other parts of the remaining Ottoman territory. Italian forces were present in southwestern Anatolia and French forces occupied areas in the south. On May 15, 1919, Greek forces landed in İzmir. From there, the Greek occupation expanded further into western Anatolia.

For someone looking at the period only through the borders of modern Türkiye, it is easy to miss how uncertain the future looked in 1919. The Ottoman Empire had not simply lost a war abroad. Its government no longer exercised full authority over much of the territory it still claimed.

This was the world in which Mustafa Kemal arrived in Samsun on May 19, 1919.

Millî Mücadele and Kurtuluş Savaşı

The years that followed have two names that learners of Turkish encounter constantly: Millî Mücadele and Kurtuluş Savaşı.

Millî Mücadele means the National Struggle. Kurtuluş Savaşı is usually translated as the Turkish War of Independence, although kurtuluş itself means liberation or deliverance.

Mustafa Kemal became the central political and military leader of this movement, but the familiar Turkish expression Mustafa Kemal ve silah arkadaşları points to the wider group around him. Silah arkadaşı literally means a companion in arms.

Commanders such as İsmet İnönü, Fevzi Çakmak and Kâzım Karabekir played major roles, alongside members of the new parliament, local resistance organizations, soldiers and civilians.

Ankara gradually became the political center of the movement. On April 23, 1920, the Grand National Assembly opened there. There were now two competing centers of political authority: the Ottoman government in occupied Istanbul and the nationalist movement centered on the assembly in Ankara.

At the Sivas Congress in September 1919, the question of foreign mandate or protection was one of the issues facing the nationalist movement. Mustafa Kemal later described the fundamental choice of this period in Nutuk with a phrase that remains immediately recognizable in Turkish:

“Ya istiklâl ya ölüm.”

“Independence or death.”

The word is istiklâl. We will come back to it, because modern Turkish usually uses a different word for independence.

Sèvres and the future that did not happen

In August 1920, while the National Struggle was already underway, representatives of the Ottoman government signed the Treaty of Sèvres with the Allied powers.

The treaty helps explain what was at stake.

The Ottoman Empire had already lost most of its Arab territories. Sèvres envisaged an Armenian state in the east, Greek administration of the İzmir region followed by a later process over its status, international control of the Straits, and extensive foreign influence and zones of control. What remained under direct Ottoman sovereignty would have been much smaller and much more restricted than before the war.

The Ankara government rejected the treaty.

Sèvres never became the final settlement. That fact can sound inevitable when we look backward from modern Türkiye. It was not inevitable to the people living through 1920.

The Ottoman Empire had lost the First World War. Istanbul was occupied. İzmir was occupied. Foreign armies controlled or operated in different parts of Anatolia. Much of the former empire had already passed into mandates, new states or other political arrangements.

The question was what would happen to Anatolia.

From resistance to a regular army

The National Struggle lasted for years, on several fronts and through periods when its outcome was uncertain. Local resistance forces were gradually brought into a regular army. There were military victories and defeats, political disputes and negotiations.

For the story of August 30, we do not need to follow every battle.

By 1921 the Ankara government and its army had survived some of the most dangerous stages of the war. The Greek advance was stopped at the Battle of Sakarya. The Grand National Assembly gave Mustafa Kemal the title Gazi and the rank of Mareşal after that victory.

Greek forces, however, still occupied a large part of western Anatolia.

For months, the Turkish command prepared an offensive intended to end that situation.

The preparations were kept remarkably quiet. On July 28, 1922, a football match between military teams was arranged at Akşehir. It gave senior commanders a reason to gather without openly announcing a military planning meeting. Mustafa Kemal later described in Nutuk how the commanders were called there under the pretext of watching the match.

Another piece of misdirection followed in August. A newspaper announcement said Mustafa Kemal would host diplomats for tea in Çankaya on August 21.

There was no tea party. By then he had already left Ankara for the front.

August 30

The Büyük Taarruz, the Great Offensive, began before dawn on August 26, 1922.

Mustafa Kemal directed the operation from Kocatepe near Afyon together with the senior command. The offensive broke through Greek defensive positions, and the fighting continued over the following days.

One of the more difficult stories from these days belongs to Colonel Reşat Bey and Çiğiltepe. Reşat Bey, commander of the 57th Division, had told Mustafa Kemal that his troops would take the fortified position within half an hour. When they had not done so by the promised time, he took his own life. Çiğiltepe was captured shortly afterward.

When surnames were introduced in Türkiye in 1934, Atatürk gave his family the surname Çiğiltepe.

On August 30, the offensive reached its decisive point around Dumlupınar.

The battle became known as the Başkumandanlık Meydan Muharebesi, the Battle of the Commander-in-Chief, because Mustafa Kemal directed it personally. A large part of the Greek army was surrounded and defeated, and its organized position in western Anatolia collapsed.

The war did not end on August 30. On September 1, Mustafa Kemal issued an order that remains familiar in Türkiye:

“Ordular! İlk hedefiniz Akdeniz'dir. İleri!”

“Armies, your first objective is the Mediterranean. Forward.”

The pursuit continued westward, and Turkish forces entered İzmir on September 9. August 30, however, was the decisive military victory. That is the zafer commemorated in Zafer Bayramı.

What was actually won?

The importance of August 30 lies in what the victory changed. Four years earlier, the Ottoman Empire had ended the First World War defeated. Its army had been demobilized and its capital occupied. By 1920, the Treaty of Sèvres had set out a postwar settlement that would leave Anatolia divided among different forms of sovereignty, administration and foreign influence.

The victory at Dumlupınar overturned the military situation in western Anatolia. Within days, the Greek occupation of İzmir was over, and the settlement envisioned at Sèvres could no longer be imposed in the form agreed in 1920. Military victory was followed by negotiations, first at Mudanya and then at Lausanne.

This makes the Turkish experience after the First World War unusual. Large parts of the former Ottoman Empire passed under British and French mandates or into other political arrangements after the war. In Anatolia, the nationalist movement established its own parliament and army, challenged the settlement accepted by the Ottoman government, and eventually negotiated international recognition of a new political order.

August 30 did not establish the Republic. That came on October 29, 1923, after a much longer history of Ottoman constitutional and political reform. But by the end of August 1922, the military conditions that had made the postwar settlement of 1920 possible had changed decisively.

From Mondros to Mudanya, from Sèvres to Lausanne

The period can also be followed through four names: Mondros, Sèvres, Mudanya, Lausanne.

Mondros came after defeat in 1918. It ended Ottoman participation in the First World War and opened the period in which Allied occupation expanded.

Sèvres came in 1920. It represented the postwar settlement accepted by the Ottoman government but rejected by the nationalist movement in Ankara.

The Mudanya Armistice was signed in October 1922, after the victory at Dumlupınar and the Turkish advance to İzmir. It brought the fighting to an end and provided for the return of Eastern Thrace to Turkish administration without another major battle.

The final peace settlement came with the Treaty of Lausanne on July 24, 1923. Lausanne internationally recognized the new political reality that had emerged from the National Struggle.

A few months later, on October 29, 1923, the Republic of Türkiye was proclaimed.

This sequence also explains why August 30, September 9 and October 29 are close to one another in Turkish historical memory without being interchangeable. August 30 commemorates zafer, the military victory. September 9 is İzmir's kurtuluş, its liberation. October 29 is Cumhuriyet Bayramı, Republic Day.

A word that changed with Turkish

There is another piece of this history hidden in the language.

Today, the ordinary Turkish word for independence is bağımsızlık. A learner will see it in phrases such as Türkiye'nin bağımsızlığı, Türkiye's independence.

But that is not the word Mustafa Kemal used in the phrase from the National Struggle:

Ya istiklâl ya ölüm.

The word istiklâl is Arabic in origin and belonged naturally to the political vocabulary of the late Ottoman and early Republican period. It is also the word in İstiklâl Marşı, the name of Türkiye's national anthem.

Bağımsız and bağımsızlık became established in standard Turkish later, as the vocabulary of Turkish changed during the Republican language reforms. Modern Turkish therefore often describes the goal of the National Struggle as bağımsızlık, even though people of the period commonly spoke of istiklâl.

The older word did not disappear. It remains in historical language and in established names.

For someone learning Turkish, these differences are useful beyond this particular holiday. Zafer, kurtuluş, istiklâl, bağımsızlık and cumhuriyet can all appear in English accounts under the broad history of Turkish independence. In Turkish, they point to different parts of that history.

How August 30 became Zafer Bayramı

The battle was commemorated at Dumlupınar before Zafer Bayramı became an official national holiday. A major ceremony was held there in 1924, on the second anniversary of the victory, with Mustafa Kemal in attendance.

On April 1, 1926, the Grand National Assembly passed Kanun No. 795, the Zafer Bayramı Kanunu.

The law identified August 30, the day of the Başkumandan battle, as the victory day of the Republic's army and navy and provided for annual military ceremonies, including a ceremony at Dumlupınar.

The date was therefore tied specifically to the decisive military victory. İzmir had its liberation on September 9, and the Republic would have its own anniversary on October 29.

What Zafer Bayramı looks like now

August 30 remains an official public holiday in Türkiye. Government offices close, while many shops, restaurants and cafés remain open.

Official ceremonies take place at Anıtkabir in Ankara and around Dumlupınar, and municipalities organize commemorations and public events in cities across the country. Turkish flags appear on balconies, streets and public buildings. Military displays and commemorative flights may also form part of the program, depending on the year and location.

The language surrounding the day still carries the different stages of this history.

News reports and commemorations use words such as Büyük Taarruz, Başkomutanlık Meydan Muharebesi, zafer, kurtuluş, Millî Mücadele and istiklâl.

Knowing where those words belong makes it easier to understand what is actually being remembered on August 30.
