This barbaric period in history saw the death of over six million Jews. The Holocaust Encyclopedia describes it as 'the systematic, bureaucratic, state-sponsored persecution and murder' of these individuals. The Nazis, who rose to power in Germany in 1933, saw Jews as racially inferior. As part of the 'Final Solution' the Nazis killed 2 out of every 3 Jews. Their eugenics movement aimed to stop the weak from procreating. The barbaric means by which this was carried out was compulsory sterilisation, segregation or institutionalisation of anyone deemed to be unfit. Ultimately, eugenics became an umbrella under which ethnic genocide could be justified in Nazi Germany. It was a devastating period of the twentieth century.
