After the Ottoman Empire entered World War I, leaders increasingly treated Armenians as a security threat. This wartime framing helped justify extraordinary measures that soon turned into mass deportations and violence. The result was a fast-moving refugee crisis across Anatolia and into the wider Middle East.
In Van province, Armenians organized armed defense amid mass violence and siege conditions. As fighting intensified, civilians fled from surrounding areas into the city and later toward safer regions as front lines shifted. These movements marked an early, large refugee flow tied directly to survival during the genocide.
Ottoman authorities arrested hundreds of Armenian community leaders and intellectuals in Constantinople (Istanbul). This action is widely treated as the symbolic start of the Armenian Genocide because it removed leadership and spread fear. Families soon faced deportation orders and the risk of being separated permanently.
The Ottoman government adopted the Temporary Law of Deportation (Tehcir Law), authorizing forced relocation during wartime. In practice, it enabled widespread deportations of Armenians from their homes, often in convoys under guard. Many deportees became refugees en route, lacking shelter, food, or legal protection.
Large numbers of deported Armenians were driven toward camps and holding areas around Deir ez-Zor in the Syrian desert. Survivors arriving there were often destitute, and many died from starvation, disease, and killings. The desert camps became a central endpoint of the deportation routes and a symbol of mass death.
Armenians from several villages in the Musa Dagh region resisted deportation and held out for weeks. French warships evacuated thousands of survivors and transported them to Port Said, Egypt. The rescue turned a local refuge effort into an international refugee transfer across the Mediterranean.
In the United States, a relief network formed in 1915 to respond to mass suffering in the Ottoman region, including Armenians. The organization later became known as Near East Relief and supported refugees with food, medical care, and orphan care. Humanitarian assistance became a key factor shaping where survivors could live and rebuild.
After World War I, the Treaty of Sèvres included provisions pointing toward an independent Armenia and major territorial changes in the former Ottoman lands. Turkish nationalist rejection and renewed war meant the treaty was not implemented. For refugees, the failure of these plans reduced prospects for a protected return to homes in Anatolia.
France signed the Treaty of Ankara with the Turkish nationalist government, agreeing to evacuate Cilicia. As French forces pulled back, many local Christians—including Armenians—left with them or fled to areas under French mandate, fearing retaliation and loss of security. This created another major refugee wave into Syria and Lebanon.
The League of Nations introduced the Nansen passport as an internationally recognized identity and travel document for stateless refugees. Many Armenians, unable to rely on a protecting state, needed such documents to cross borders, work, or resettle legally. The policy helped turn emergency flight into longer-term diaspora formation across multiple countries.
After Turkish forces captured Smyrna (İzmir), a catastrophic fire destroyed much of the city, including Greek and Armenian quarters. Hundreds of thousands of people crowded the waterfront seeking evacuation, creating a sudden humanitarian emergency. Many Armenians who had already been displaced elsewhere were swept into this new refugee surge across the Aegean.
The Treaty of Lausanne recognized the boundaries of modern Turkey and replaced the unimplemented Treaty of Sèvres. The Allies dropped demands related to ceding territory to Armenia, making large-scale Armenian return to Anatolia far less likely. By 1923, refugee survival, resettlement, and statelessness had become long-term conditions, shaping enduring Armenian diaspora communities in the Middle East, Europe, and beyond.
