State Sovereignty Enforcement Day, or Hari Penegakan Kedaulatan Negara, is observed in Indonesia every March 1. This day commemorates the 1949 Yogyakarta General Offensive, a significant event in the Indonesian National Revolution that demonstrated the nation's ongoing struggle for independence from Dutch colonial rule. The offensive, led by Lieutenant Colonel Suharto, successfully captured Yogyakarta for a brief period, showcasing Indonesia's determination to fight for its sovereignty. Although not a non-working holiday, it serves as a special observance to honor those who fought for Indonesia's independence and to promote national unity and pride. Celebrations in Yogyakarta typically include parades and various festive activities, reflecting the historical importance of the day. The designation of March 1 as State Sovereignty Enforcement Day was made in February 2022.
