Answer:
The idea of imperialism contributed to the genocide of Armenians in 1915, before, and during, the First World War, because the Muslim Ottoman Empire, who had invaded Armenia, and took control of the whole of what is today Turkey, wished to force Eastern Armenians to convert from Christianity, into Islam.
The invasion, and control of what is today Turkey, historically known as Armenia before, by the Ottoman Empire, began with the signing of the Peace of Amasya, in 1555, and later by the Treaty of Zuhab, in 1639. Although in the beginning the Ottomans left the Armenian population, especially the Christian Armenians alone, forcing them into communities known as millets, this did not remain always so, as the Ottoman Muslims began to force conversion from the Armenians. In the end, the whole thing ended when in 1915, maybe even before then, the Ottoman Turks began to force Armenians to move towards the Syrian Desert. While they deported the infirm, injured, women and children and forced them on death marches, they outright began killing the young and able-bodied men. This was later known as the Armenian genocide, the second most reknown case of mass killings, after the Jewish Holocaust.
