Can anyone give me any details about genocide (during the Holocaust) ?

Genocide is the deliberate killing of a large group of people, especially those of a particular ethnic group or nation.

The Holocaust took place from 1939 to 1945 and involved the genocide of more than 6 million Jews, and more than 11 million people in total. This systematic mass murder occurred after the rise of Adolf Hitler and under his reign of a totalitarian state of government.
