Around 1850, the Bansko Municipality was founded - an organization of local Bulgarian self-government, a continuation of the general village council formed in 1833, headed by Lazar German, to provide funds, materials and manpower for the construction and decoration of the Holy Trinity Church, consecrated in 1835. The municipality's leadership includes influential representatives of the trade and craft industry. In the 1860s and 1870s the municipality headed the struggle against the Greek ecclesiastical authorities, for the independence of the Bulgarian church and for the development of enlightenment in the village. At its initiative, a new school building was built in 1857, the mutual school was reorganized into classrooms, and the Revival newspapers and books were distributed. The municipality organized the construction of a bell tower for the Holy Trinity Church in 1850 and the installation of a clock in 1865.
