In this paper, the author presents the results of the Tanzimat principle of electoral equality of Muslims and non-Muslims in the District of Banja Luka and its subdistricts. By the Tanzimat regulation of electoral equality, the author refers to those parts of the 1864 Ottoman Vilayet Law and its 1867/1871 amendments that regulate the equality of Muslims and non-Muslims in terms of electing their representatives in the local councils. In that sense, this paper does not present the implementation of the entire Vilayet Law, the entire administration and its bodies and services, but only refers to the local councils at the levels of sanjak and kaza. The paper has been written on the ground of relevant references, while the Ottoman annual reports for the Vilayet of Bosnia were the sources for the data regarding the councils. A general assessment is that the electoral equality in the said area was mostly respected, but not entirely since there were obvious deviations from the Law.
