The ethnic population that was brutally killed due to the nationalism and prejudice of the young turks was the <u>Armenians</u>, because towards April 24, 1915, the Ottoman Empire in Turkey decided to extermine 1.500.000 Armenians, that majorly lived inside the Ottoman Empire. That Genocide was carried out during and after the World War I, and <u>was caused by the Ottoman Authorities and young turks prejudices against Armenians, where to justify the massacre of 1915, they invented a year before that the Armenians who lived in the empire were a danger and a threat to the security of the empire,</u> so <u>that prejudgements were the main aspect that induced the brutal killing of the Armenians.</u>
