The Armenian genocide (1915–1916) refers to the physical destruction of Armenian Christian people in the Ottoman Empire. It is sometimes referred to as the first genocide of the 20th century.

Then came the Jewish genocide, to eliminate the Jews by the Nazis. Are you starting to see the time period you are talking about.
