About May 21

May 21 is a day that celebrates cultural diversity and national identity on multiple fronts. The United Nations recognizes it as World Day for Cultural Diversity for Dialogue and Development, while Montenegro marks its 2006 independence referendum, when 55% of voters chose to break from the State Union of Serbia and Montenegro. In Colombia, Afro-Colombian Day commemorates the 1851 abolition of slavery in that nation, honoring the enormous contributions of Afro-Colombian communities. Meanwhile, the Circassian people observe a solemn Day of Mourning, remembering the 1864 end of the Russo-Circassian War and the subsequent forced exile of countless Circassians from their homeland.

Aviation milestones define this date as well. Five years after Lindbergh's legendary Paris landing, Amelia Earhart was forced by bad weather to put down in a pasture in Derry, Northern Ireland — making her the first woman to complete a solo transatlantic flight. The spirit of exploration extended into space in 2010, when Japan's JAXA launched IKAROS, the first spacecraft to deploy a solar sail in deep space, aboard an H-IIA rocket.

From the founding of FIFA in Paris in 1904 to the enactment of France's Taubira law in 2001 — which officially recognized the Atlantic slave trade as a crime against humanity — May 21 has repeatedly been a date when the world took steps, large and small, toward connection, recognition, and progress.
