History

The anniversary of the founding of Boyolali is celebrated on 5 June, as the government of Kasunanan Surakarta created a new rule about the village government or the government outside the Kuthanegara (Capital City) on 5 June 1847. The rule was adopted pursuant to the treaty of Serat Perjanjian Dalem Natha entered into between Pakubuwono VII and the Dutch Government in the belief that the incumbent government was unable to fully function. The treaty is in the treaty of Serat Perjanjian Dalem Natha page 140 – 146 or in Staatsblad 1847 No. 30. Chapter 30 – 36. According to Staatsblad in 1847 No.30, the Government of Kasunanan Surakarta formed six "Mountain Regencies" in its surrounding area to help the government in those regions. The six regions were the City of Surakarta and the then existent five Regencies of Kartosuro, Klaten, Boyolali, Ampel and Sragen. (Pawarti Surakarta, 1939:71). Based on that Staatsblad, the anniversary of the Boyolali Regency was 5 June 1847.
