Final answer:
The Armenians suffered genocide by the Ottoman Turks from 1915 to 1923, with over 1.5 million people killed. The genocide is recognized internationally, but the Turkish government denies it.
Step-by-step explanation:
The group that suffered genocide at the hands of the Ottoman Turks was the Armenians. During the period of 1915 to 1923, the Young Turk government of the Ottoman Empire orchestrated a campaign of extermination against the Armenian population, which was predominantly Christian and seen as a potential threat due to their religious and geographical ties to the Russians. This systematic atrocity involved the massacre and forced deportation of Armenians, with over 1.5 million people annihilated. Despite clear historical evidence and international recognition, the Turkish government continues to deny the occurrence of the Armenian Genocide.
