Cause

Following military defeats in the 1912–1913 Balkan Wars and wartime invasions, CUP leaders feared that Armenians in Anatolia — regarded as the Turkish nation's last territorial refuge — would seek independence. Isolated acts of Armenian resistance were interpreted as evidence of widespread rebellion, prompting Ottoman authorities to resolve the perceived threat permanently through expulsion and annihilation.

Event

Beginning on 24 April 1915, Ottoman authorities arrested hundreds of Armenian intellectuals in Constantinople. Under orders from Talaat Pasha, an estimated 800,000 to 1.2 million Armenians were subjected to death marches to the Syrian desert in 1915–1916, deprived of food and water, subjected to massacres and rape, and held in concentration camps. A second wave of massacres in 1916 left roughly 200,000 survivors; 100,000–200,000 women and children were forcibly converted to Islam.

Consequence

The genocide destroyed more than two thousand years of Armenian civilization in eastern Anatolia and, alongside the persecution of Assyrian and Greek Orthodox Christians, facilitated the creation of an ethnonationalist Republic of Turkey. Massacres of Armenian survivors continued through the Turkish War of Independence. As of 2025, 34 countries recognize the event as genocide, while the Turkish government continues to contest that characterization.
