Constitutional Assembly elections were held in Bulgaria in April 1893.
The body known as the Grand National Assembly (Bulgaria: Велико народно събрание - Veliko narodno subranie) was convened for a fourth time in order to consider several amendments to the constitution, including ones concerning the religion of the monarchy and a reduction in the number of members of the National Assembly.
[1][2] The existing constitution required the monarch to be a member of the Bulgarian Orthodox Church, although it exempted the first Prince.
As Prince Ferdinand was the first of a new dynasty, he was considered to be exempt (as a Roman Catholic).
The amendments would also reduce the number of members of the Grand National Assembly from one for every 5,000 citizens to one for every 10,000.
