Answer:
Nationalist sentiments led to the persecution of the Armenians.
Step-by-step explanation:
Diverse ethnic and religious groups were allowed to practice their beliefs in their own communities. In the late 1890s, nationalism sparked tension between the ottoman rulers and minorities. The Ottomans worried about their empire breaking up which led to persecution, then genocide of the Armenians who practiced Christianity.
Muslim Turks accused Christian Armenians of supporting Russian plans against the Ottoman empire. They then made policies that repressed the Armenians, who protested these policies. The genocide of Armenian people claimed well over a million lives and continued to grow even during World War I.
