Hi,
Could you please provide additional context regarding your question (e.g., time period, country of reference, discriminated group in question)?
The universal declaration of human rights, while ratified in 1948 and most well known for having been borne due to the atrocities of the Holocaust, was actually created in response to the egregious widespread human rights violations and war crimes that had transpired during both World Wars and by numerous nations.
While Hitler's Nazi regime and genocide of the Jewish people was arguably the impetus for the document (and subsequently the creation of the UN), it was not solely concerning the Holocaust or Jewish victims of the Nazi regime, but rather extended to all the scores of civilian casualties systematically perpetrated in the late 20th century and even prior, ranging from the murderous regimes of Mussolini to Stalin to Hirohito, to U.S.' usage of atomic bombs, internment camps and prior history of slavery.
The universal declaration of human rights effectively guarantees the equal rights, liberty and humane treatment of all people, irrespective of religion, ethnicity, race, nationality, gender, political affiliation, etc. It guarantees, among other things, the freedom of speech, movement, religion, life, healthcare, and housing, and unilaterally outlaws all torture.
