1886 Spanish general election

A general election was held in Spain on Sunday, 4 April (for the Congress of Deputies) and on Sunday, 25 April 1886 (for the Senate), to elect the members of the 4th Restoration Cortes. All 434 seats in the Congress of Deputies were up for election, as well as 180 of 360 seats in the Senate. The electorate comprised about 4.6% of the country's population.

During this period, an informal system colloquially known as El Turno Pacífico (English: The Peaceful Turn) was operated by the two main parties in the country—the Conservatives and the Liberals—to determine in advance the result of the election, often through the encasillado, caciquism and election rigging, ensuring that both parties would have alternating periods in power. As a result, elections were often neither truly free nor fair, though they could be more competitive in the country's urban centres where this system was weaker.

The election resulted in a large majority for the government-supported candidates of the Liberal Party, which was possible through Antonio Cánovas del Castillo's peaceful handover of power to Práxedes Mateo Sagasta, in what came to be known as the Pact of El Pardo. Running against the pact were the Francisco Romero Robledo and José López Domínguez-led factions within the Conservative and Liberal parties, respectively, but which failed to achieve decisive breakthroughs. The resulting legislature would come to be known as the "Long Parliament" (Spanish: Parlamento Largo): lasting from 1886 to 1891, it would be the only one during the Restoration period to last its full five year-term.
