The Day of the Macedonian Revolutionary Struggle is observed in the Republic of North Macedonia every October 23. This public holiday commemorates the establishment of the Internal Macedonian Revolutionary Organization (IMRO) in 1893, founded in Thessaloniki by anti-Ottoman Macedonian Bulgarian revolutionaries. The IMRO aimed to gain autonomy for Macedonia within the Ottoman Empire and was notably involved in the Ilinden Uprising of 1903, which, despite its failure, marked a significant moment in the Macedonian revolutionary struggle. The holiday pays tribute to all heroes who fought for the independence of North Macedonia and is marked by official speeches, solemn ceremonies, and various events throughout the country. The IMRO played a crucial role in the liberation of Macedonia during World War II, and although it ceased to exist after the rise of communism in Yugoslavia, its legacy continues to be honored on this day.
