In Spanish politics, the turnismo, turno pacífico or simply turno (Spanish for "turn" or "shift") refers to an informal two-party system of government within the constitutional monarchy of the Restoration. It consisted of the alternation in government of the two dynastic parties (the Conservative and the Liberal parties) through systematic electoral fraud which ensured that the party that called the elections always won.
The system was in place from 1879, the first elections held under the Restoration, until 1918, when it began to break down in response to public influence during World War I, and was ultimately abandoned after the election of 1923 and coup d'etat of Miguel Primo de Rivera.
