History of National DEI Day
National DEI Day was established to align with September 17, a date already rich in national significance. On this day in 1787, the U.S. Constitution was signed. In 2004, Congress designated September 17 as Constitution Day and Citizenship Day, which are officially recognized by the U.S. government. These observances remind us of our shared responsibilities as citizens, and National DEI Day extends this reflection to the ongoing work of ensuring democracy is equitable and inclusive for all.
The holiday’s roots run deep in Nashville, Tennessee. At Fort Negley, thousands of formerly enslaved people helped build the stronghold and later donned the Union blue to fight for freedom and preserve the nation. This history inspires the color blue as the holiday’s unifying symbol. Blue symbolizes trust, justice, and freedom, and is deeply rooted in our national identity as one of the three colors of the American flag. It also inspired the founding of Carpe Acqua DEI, the mission-driven water brand that launched on Juneteenth 2025 at Fort Negley.
Carpe Acqua DEI, meaning “Embrace the Water of DEI,” and “DEI” meaning “God” in Latin, is more than a beverage—it is a movement. Born where freedom fighters once stood, it reclaims DEI as the source of life, strength, dignity, and as our creator. National DEI Day affirms that diversity strengthens democracy, equity ensures fairness, and inclusion fosters unity. It calls on us to wear blue, to stand together, and to recognize that DEI is not dead, it is alive and flowing like water.
