General elections were held in San Marino on 13 June 1915 to elect the fourth term of the Grand and General Council.[1]
According to the decisions of the Meeting of 1906, a third of the seats in the Grand and General Council should be renewed every three years. The twenty councillors elected in 1906 finished their term this year.
All councillors were elected in their constituency using a plurality-at-large voting, a non-partisan system. However, as previously happened, candidates elected generally belonged to the liberal group which had supported the democratic action of the Citizenry Meeting or, more, were members of the sole organized party of the country, the Sammarinese Socialist Party. This time the Socialists refused to join the government they left in 1913 following the reject of their fiscal reform.[2]
Voters had to be citizens of San Marino, male, the head of the family and 24 years old.
