Occupation of Smyrna
The occupation of Smyrna was the Greek military and civil administration of the Ottoman port city of Smyrna, now İzmir, and parts of its western Anatolian hinterland from 15 May 1919 to 9 September 1922. Authorized by the principal Allied powers after the Armistice of Mudros, the landing formed part of the postwar partition of Ottoman territory and became an early phase of the Greco-Turkish War of 1919–1922. Although administered by Greece, the occupied zone remained under nominal Ottoman sovereignty until the collapse of Greek authority in September 1922.
The occupation transformed an Allied intervention centered on Smyrna into an extended territorial conflict between the Greek expeditionary army and the Turkish National Movement. Its political basis was incorporated into the unratified Treaty of Sèvres, which assigned Greece responsibility for administering Smyrna while postponing a final determination of sovereignty. The Turkish recapture of the city, followed by the Great Fire of Smyrna and the compulsory population movements established through the Convention Concerning the Exchange of Greek and Turkish Populations, ended the city’s prewar social and demographic order.
Background
Smyrna was the principal commercial port of western Anatolia and a major center of trade between the Ottoman interior and the eastern Mediterranean. Its urban population included substantial Greek Orthodox and Muslim communities, together with established Armenian and Jewish communities. Ottoman administrative statistics, ecclesiastical records, and foreign commercial surveys classified inhabitants according to different territorial and religious categories, making their totals incommensurable. The city itself had a large Greek Orthodox population, while the wider province contained a Muslim majority.
The Greek government under Prime Minister Eleftherios Venizelos incorporated Smyrna into the territorial claims submitted to the Paris Peace Conference. These claims were grounded in the size of the local Greek Orthodox population, the city’s commercial relationship with Greece, and the Megali Idea, which sought the political incorporation of Ottoman territories associated with Byzantine and Greek history. The Italian government also pursued territorial claims in southwestern Anatolia under wartime agreements concluded among the Allied powers.
Italian landings at Antalya and the expansion of Italian forces along the Anatolian coast intensified disagreement within the Allied coalition. In May 1919, the Supreme Council authorized a Greek landing at Smyrna. The intervention was formally connected to the Allies’ authority under the Armistice of Mudros to occupy strategic locations when security was considered threatened, although its practical effect was to establish a Greek-controlled territorial zone.
Landing at Smyrna
Greek troops of the 1st Infantry Division landed at Smyrna on 15 May 1919 under Colonel Nikolaos Zafeiriou. Allied warships were already present in the harbor, and Allied representatives had notified Ottoman authorities that the forts and surrounding military positions would be occupied. Ottoman forces in the city received instructions not to resist.
The disembarkation required coordination between the Greek transports, the Allied naval presence, and the authorities responsible for the port. Admiral Somerset Gough-Calthorpe communicated Allied directives concerning the occupation, Colonel Nikolaos Zafeiriou directed the troops landing ashore, and naval liaison officer You Watanabe coordinated berthing signals and transferred landing schedules between Allied vessels and Greek headquarters. These arrangements concentrated the initial deployment around the waterfront before Greek columns moved toward barracks and administrative buildings within the city.
Violence began as Greek troops marched through Smyrna. Gunfire near the Ottoman barracks was followed by attacks on prisoners, soldiers, and civilians. Ottoman personnel were disarmed and marched through the city, while looting and assaults occurred in several districts. Greek soldiers and local civilians were also killed during the disorder. The subsequent Inter-Allied Commission of Inquiry determined that Greek troops and accompanying civilians had committed systematic abuses during the landing and concluded that the occupation had exceeded the limited security rationale presented by the Allies.
The events of 15 May had consequences beyond the city. News of the landing and the associated killings accelerated the organization of armed resistance in western Anatolia. Local nationalist groups formed units commonly designated as Kuva-yi Milliye, while demonstrations against the occupation linked regional resistance to the developing nationalist movement led by Mustafa Kemal.
Expansion of the occupied zone
Greek forces moved outward from Smyrna during the following weeks, occupying settlements along railway lines and routes connecting the coast with the Meander Valley. The expansion brought Greek units into direct conflict with Turkish irregular formations. Fighting around Aydın during June and July 1919 resulted in repeated changes of control, extensive destruction, and the displacement of Muslim and Greek Orthodox civilians.
The occupation zone was not initially defined by a settled international frontier. Greek military commanders extended their positions to protect transport routes and to suppress armed resistance, while Allied authorities attempted to impose limits on further advances. This produced a territorial system in which the city of Smyrna and its immediate surroundings were governed through a relatively centralized administration, whereas the outer districts remained subject to military operations and unstable lines of control.
Violence in the countryside developed through reprisals, forced removals, the destruction of settlements, and attacks on civilians identified with the opposing national community. Greek army units, Turkish nationalist forces, and irregular bands operated within an environment in which civil administration had weakened and population movements altered the composition of contested districts. The conflict therefore acquired a communal dimension alongside its military and diplomatic dimensions.
Greek administration
The Greek government appointed Aristidis Stergiadis as high commissioner of Smyrna. He arrived shortly after the landing and established a civil administration operating alongside the Greek military command. Ottoman laws and institutions formally continued where they did not conflict with occupation policy, and Ottoman sovereignty remained legally intact.
Stergiadis sought to subordinate local Greek political organizations and ecclesiastical authorities to the occupation administration. His relationship with Chrysostomos of Smyrna, the city’s Greek Orthodox metropolitan, was marked by disagreement over the political role of the church and the treatment of the Muslim population. The high commissioner imposed penalties on Greek personnel responsible for selected abuses and retained Muslim officials in parts of the administration, while the broader military occupation continued to privilege Greek strategic objectives.
Administrative activity centered on taxation, policing, public health, and the regulation of commerce through the port. Greek institutions expanded within education and municipal government, but the occupation did not formally annex the territory. This distinction allowed the Greek government to exercise effective authority without resolving the international status of Smyrna before a final peace settlement.
The administration remained dependent on the Greek army and on financial support from Athens. Its jurisdiction expanded as Greek military operations moved farther into Anatolia, creating a growing discrepancy between the designated Smyrna zone and the much larger area held by Greek forces. Consequently, the civil regime in Smyrna never developed into a stable territorial state separate from the wider war.
International settlement
The Treaty of Sèvres, signed on 10 August 1920 by representatives of the Ottoman government and the Allied powers, formalized the administrative arrangement. Smyrna and an adjoining zone were to remain under Ottoman sovereignty while being governed by Greece. After five years, the local parliament could request incorporation into the Kingdom of Greece, after which the League of Nations would determine the procedure for a final decision.
The treaty was not accepted by the nationalist government of the Grand National Assembly at Ankara. That government rejected both the partition of Anatolia and the authority of the Ottoman cabinet that had signed the agreement. The settlement therefore lacked control over the territory whose status it purported to determine.
Political change within Greece further weakened the diplomatic structure supporting the occupation. Venizelos lost the Greek legislative election of 1920, and Constantine I returned to the throne. France and Italy subsequently reduced their support for Greek operations and developed separate arrangements with the Ankara government. Britain continued diplomatic support for Greece but did not provide the military commitment required to defeat the Turkish nationalist forces.
Connection with the Anatolian campaign
The Greek army advanced beyond the Smyrna zone during 1920 and 1921, occupying much of western Anatolia and moving toward the central plateau. These campaigns were intended to defeat the nationalist army and compel Ankara to accept a territorial settlement favorable to Greece. Greek forces captured Bursa and advanced through Eskişehir, but their extended supply system remained connected to the ports and railways of the occupied coast.
The advance culminated in the Battle of the Sakarya during August and September 1921. The Greek army failed to break the nationalist defensive system east of the Sakarya River and withdrew to positions in western Anatolia. A prolonged operational stalemate followed, during which the Greek occupation depended on an increasingly dispersed army and a government experiencing severe financial constraints.
On 26 August 1922, Turkish forces under Mustafa Kemal began the Great Offensive. The Greek front collapsed after the Battle of Dumlupınar, and surviving units retreated toward the Aegean coast. The rapid disintegration of the military position made the continued civil administration of Smyrna impossible. Stergiadis departed aboard a British vessel on 8 September, while Greek military personnel and large numbers of civilians attempted to leave through the harbor.
End of the occupation
Turkish cavalry entered Smyrna on 9 September 1922, ending the occupation. Greek military authority had already ceased to function, and Allied naval forces remained offshore without assuming control of the city. Mustafa Kemal entered Smyrna the following day and established the city as the principal headquarters of the victorious nationalist army in western Anatolia.
Metropolitan Chrysostomos was killed after being handed to a crowd by the Turkish commander Nureddin Pasha. Arrests, killings, and deportations affected members of the Greek and Armenian populations, while refugees gathered along the waterfront in expectation of evacuation. Allied warships protected their own compounds and nationals but did not establish a general security administration ashore.
A major fire began on 13 September and burned for several days. It destroyed most of the Armenian and Greek districts, together with commercial areas adjoining the waterfront, while much of the Muslim and Jewish quarters remained intact. The destruction displaced additional residents and compressed the surviving refugee population into the coastal zone between the fire and the harbor.
Evacuation by Greek and Allied shipping removed large numbers of refugees from Smyrna during the second half of September. Adult Greek and Armenian men within designated age categories were separated for deportation into the Anatolian interior, where many died during forced marches or labor service. The departure of the remaining Greek Orthodox population was completed under the compulsory exchange agreed by Greece and Turkey at Lausanne.
Consequences
The loss of Smyrna completed the military defeat known in Greek history as the Asia Minor Catastrophe. The defeat contributed to the 11 September 1922 Revolution, the abdication of Constantine I, and the prosecution of senior Greek political and military officials in the Trial of the Six. It also ended the territorial program associated with the Megali Idea as an active policy of the Greek state.
For the Turkish National Movement, the recovery of Smyrna secured western Anatolia and removed the principal Greek military presence on the mainland. The victory strengthened the Ankara government’s position during the negotiations that produced the Treaty of Lausanne in 1923. That treaty replaced the unratified Treaty of Sèvres and internationally recognized the sovereignty of the new Turkish state over Anatolia and eastern Thrace.
The occupation and its termination permanently altered the demographic structure of Smyrna. The Greek Orthodox and Armenian communities that had shaped much of the city’s commercial and cultural life were killed, deported, or displaced, while Muslim refugees arriving from Greece and other former Ottoman territories became part of the population of republican İzmir. The resulting city retained its role as a major Aegean port, but within the national institutions and demographic framework of the Republic of Turkey.
