The history of Zero Discrimination Day dates back to the early 1990s, when a global movement advocating for dignity and equal rights for everyone, regardless of their background, was gaining momentum.

The first Zero Discrimination Day was officially recognized on 1 March 2020, with the aim of raising awareness about discrimination and societal norms. The day also saw the launch of campaigns by the United Nations and other international organizations, as well as individuals committed to social justice.
