The separation of the little children from their mothers
Explanation:
The Armenian genocide was performed in multiple steps and by using multiple different methods. The Armenians were systemically killed, mostly the men, dispersed throughout the country and put to live in the most inhospitable places, being separated from their families etc. The most terrible feature though from the genocide, according to Henry Wood but also by many others, was the separation of the infants and very little children from their mothers. They were taken away and moved into areas far away, never to be able to get in touch again, and this kind of cruelty was really monstrous from the Ottomans.
The Crusades were fought for the control of several cities and ports, but the main target was Jerusalem, since this was the holy land that the Church wanted to take back.
