Republic Day is observed in Kazakhstan every October 25 to commemorate the adoption of the Declaration of the State Sovereignty of the Kazakh Soviet Socialist Republic in 1990. This national holiday celebrates the historical journey of Kazakh statehood, which dates back to the formation of the Kazakh Khanate in the 15th century. The holiday was officially declared a national holiday in 1995, though it was later downgraded and removed from public holidays until it was reinstated in 2022 by President Kassym-Jomart Tokayev. Festive events celebrating Kazakhstan's sovereignty, including official ceremonies at government institutions and diplomatic missions, take place on this day. The principles outlined in the declaration emphasize the integrity and inviolability of the country's territory and the revival of Kazakh culture and identity. December 16 is recognized as a day of remembrance for national heroes who contributed to Kazakhstan's independence.
