Sadly, at one time in history or another, genocide has occured in nearly every nation of the world.
dictatorships and the rising of the new world order.
The Rwandan genocide occured because the Hutus, the most dominant ethnic group in Rwanda at the time, began persecuting Tutsis, blaming political & economic hardship on them; it was basically because of racism.
The Rwandan Genocide began in April of 1994 between the two main ethnic groups in Rwanda: the Hutus and the Tutsis. Its estimated that 800,000 of the minority Tutsis were killed by the Hutu militia during the 100 days that the genocide lasted. http://www.unitedhumanrights.org/Genocide/genocide_in_rwanda.htm
Poland, Hungary and East Germany
In 1915 Turkey launched a campaign of genocide against the Armenian people. Before the genocide there were over two million Armenians in the Ottoman Empire; after, there were fewer than 400,000.Incidentally, the man who coined the word "genocide" was a lawyer of Polish/Jewish origin who investigated the accounts of the Armenian massacres.
Both of these events occured in 1915.
Ninevah and The Assyrians were said to be about the first brutal people. Genocide began in The Middle East when a Sky God was invented in The Bronze Age. The term Genocide though comes from the Greek word Xenos meaning a people. I would say in Palestine and Israel was where it first occured . Again with advent of Christianity in Europe and the rest of world by Europeans
World War 2 occured in France and Germany mainly. == ==
yes, but those who were not near the camps (or rail networks) might not have been aware of what occured inside them.
The war initially narrowed the divisions within Germany, through the Kaiser and Burgfrieden, however as losses and problems on the homefront occured the divisions widened.
The shift in American public pinion occured when Germany sank the Lusitania.
