State Security Service Day is observed in Kazakhstan every April 21. This professional holiday was officially established in 2014 by a presidential decree to honor the State Security Service, which was formed that same year through the merger of the Presidential Security Service and the Republican Guard. The Presidential Security Service was created in 1992 following Kazakhstan's declaration of independence, with the Republican Guard established shortly thereafter. Since its inception, the State Security Service has played a crucial role in ensuring the security of significant national and international events, including presidential inaugurations and the anniversary celebrations of the capital. The day serves to highlight the importance of this agency and the achievements of its employees.
