a campaign of massacres and forced expulsions that came to be known as the Armenian genocide

"In 1915, the Ottomans turned the city, the surrounding province, and much of modern-day Turkey into a killing field, in a campaign of massacres and forced expulsions that came to be known as the Armenian genocide. The plan was to eradicate the empire’s Armenians—“a deadly illness whose cure called for grim measures”—and it was largely successful. The Ottomans killed more than a million people," (thanks Amir)
