Saturday marks 101 years since Adolf Hitler's Mein Kampf was published, the political manifesto that set forth his antisemitic ideology later implemented by the Nazi Party, according to the Jerusalem office of the Simon Wiesenthal Center, a Holocaust research and remembrance organization.

The center noted that Hitler had already expressed his antisemitic views in a 1919 letter, years before the Nazi rise to power. "Its ultimate goal, however, must unwaveringly be the removal of the Jews altogether," The letter stated.

The 1919 letter is among the artifacts displayed at the Museum of Tolerance, the Simon Wiesenthal Center's educational institution in Los Angeles. The museum documents how antisemitic ideas were transformed into state policy, mass persecution, and ultimately mass murder.
