On this date in 1863, the Kingdom of the Netherlands officially abolished slavery in its colonies, including Suriname and the Dutch Caribbean islands (formerly known as the Dutch West Indies). This day is commemorated as Keti Koti (“Chains Broken”) in Suriname and the Netherlands, marking the liberation of enslaved people.

However, even after formal emancipation, freed individuals were required to work for 10 more years under a state-mandated contract system before they gained full freedom. This period, called Staatstoezicht (State Supervision), lasted until 1873.

Today, July 1st is recognized as a day of reflection, remembrance, and celebration in Suriname, the Netherlands, and Dutch Caribbean territories such as Aruba, Curaçao, and Bonaire. It continues to be a significant event in discussions on colonial history, reparations, and racial justice.
