National Police Struggle Day (Hari Juang Kepolisian Negara) is observed in Indonesia every August 21 to commemorate the contributions of the Indonesian National Police (POLRI) to the country's struggle for independence. The day was officially established in January 2024 by Police General Listyo Sigit Prabowo to honor the Police Proclamation, which was read by Muhammad Yasin and his fellow officers in Surabaya on August 21, 1945. This proclamation marked the police's alignment with the Republic of Indonesia during the Indonesian National Revolution. Celebrations typically include commemorative ceremonies and special events that pay tribute to the national police and the heroes of the revolution. The holiday serves to highlight the historical significance of the police force's role in disarming Japanese troops and supporting the independence movement. It is distinct from National Police Day (Hari Bhayangkara), which is celebrated on July 1.
