April 8 is Holocaust Remembrance Day.....
From the United States Holocaust Memorial Museum:
"Between 1933 and 1945, the German government, led by Adolf Hitler and the Nazi Party, carried out the systematic persecution of and murder of Europe's Jews. This genocide is now known as the Holocaust.
The Nazi regime also persecuted and killed millions of other people it considered politically, racially, or socially unfit. The Allies' victory ended World War II, but Nazi Germany and its collaborators had left millions dead and countless lives shattered.
Sara Bloomfield, Director, United States Holocaust Memorial Museum:
"I think the important thing to understand about this cataclysmic event is that it happened in the heart of Europe. Germany was respected around the world for its leading scientists, its physicians, its theologians. It was a very civilized, advanced country. It was a young democracy, but it was a democracy. And yet it descended not only into social collapse but world war and eventually mass murder."
