On This Day - What happened 20 January 1942 AD

By January 1942, he had decided that the Jews, Slavs, and other deportees considered undesirable should be killed. The genocide was organised and executed by Heinrich Himmler and Reinhard Heydrich. The records of the Wannsee Conference, held on 20 January 1942 and led by Heydrich, with fifteen senior Nazi officials participating, provide the clearest evidence of systematic planning for the Holocaust.

From the outbreak of the South-East Asian theatre of World War II, Christmas Island was a target for Japanese occupation because of its rich phosphate deposits. The first attack was carried out on 20 January 1942, by Japanese submarine I-59, which torpedoed a Norwegian freighter, the Eidsvold. The vessel drifted and eventually sank off West White Beach. Most of the European and Asian staff and their families were evacuated to Perth.

Nazi racial policies, including the notion that people who were racially inferior had no right to live, date back to the earliest days of the party; Hitler discusses this in Mein Kampf. Somewhere around the time of the German declaration of war on the United States in December 1941, Hitler finally resolved that the Jews of Europe were to be "exterminated".

SS-Obergruppenführer Reinhard Heydrich, head of the Reich Security Head Office (RSHA), convened what became known as the Wannsee Conference on 20 January 1942 at Am Großen Wannsee 56–58, a villa in Berlin's Wannsee suburb.
