Investigative Committee Day is observed in Belarus every September 12 to commemorate the founding anniversary of the Investigative Committee of the Republic of Belarus, which was established on this date in 2011 by Alexander Lukashenko. The holiday recognizes the importance of the Committee in improving the quality and efficiency of preliminary investigations within the country. The origins of Belarusian investigative bodies are closely linked to the history of investigation in the Russian Empire and the Soviet Union, with significant developments occurring after the October Revolution. On this day, the chairman of the Investigative Committee and senior government officials express gratitude to the employees for their dedication, often through award ceremonies, meetings with veterans, and various events such as concerts. Investigative Committee Day was officially added to Belarus's list of professional holidays in 2016.
