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 provinces of Álava, Albacete, Ávila, Biscay, Cuenca, Guadalajara, Guipúzcoa, Huelva, Logroño, Matanzas, Palencia, Pinar del Río, Puerto Príncipe, Santa Clara, Santander, Santiago de Cuba, Segovia, Soria, Teruel, Valladolid and Zamora were allocated two seats each, whereas each of the remaining provinces was allocated three seats, for a total of 147.

The remaining 33 were allocated to special districts comprising a number of institutions, electing one seat each—the archdioceses of Burgos, Granada, Santiago de Compostela, Santiago de Cuba, Seville, Tarragona, Toledo, Valencia, Valladolid and Zaragoza; the Royal Spanish Academy; the other royal academies (History; Fine Arts of San Fernando; Exact, Physical and Natural Sciences; Moral and Political Sciences and Medicine); the universities of Madrid, Barcelona, Granada, Havana, Oviedo, Salamanca, Santiago, Seville, Valencia, Valladolid and Zaragoza; and the economic societies of Friends of the Country from Madrid, Barcelona, Havana–Puerto Rico, León, Seville and Valencia.

The monarch would play a key role in the system of el turno pacífico (English: the Peaceful Turn) by appointing and dismissing governments and allowing the opposition to take power.

[30] The death of King Alfonso XII in November 1885 at the age of 27, with no heir apparent and with her spouse—Maria Christina of Austria—poised to become queen regent under the provisions of the Constitution, had seen a prospective political crisis being averted by the secret signing of the Pact of El Pardo between Antonio Cánovas del Castillo, incumbent prime minister and leader of the Conservative Party, and Práxedes Mateo Sagasta, leader of the Liberal Party.

As a result, Cánovas peacefully handed over power to Sagasta, who earlier that year had unified the various factions within his party under the "guarantee law": an agreement under which the Liberals would develop the freedoms and rights recognized during the Democratic Sexenium in exchange for the acceptance of shared sovereignty between the King and the Cortes, a basic principle of the 1876 Constitution.

[31] For the Congress, Spanish citizens of age and with the legal capacity to vote could run for election, provided that they were not sentenced to perpetual disqualification from political rights or public offices by a final court's decision, or to afflictive penalties if no legal rehabilitation had been obtained at least two years in advance of the election, or to other criminal penalties if the serving of the sentence could not be proven before taking the office of deputy.

[36][37] For the Senate, eligibility was limited to those entitled to be appointed as senators in their own right or those who had belonged to one of the following categories: presidents of the Senate and the Congress of Deputies; deputies who had belonged to at least three different congresses or serving for at least eight terms; government ministers; other Grandees of Spain; Army's lieutenant generals and Navy's vice admirals, two years after their appointment; ambassadors after two years of service and plenipotentiary ministers after four; other members and prosecutors of the Council of State, the Supreme Court, the Court of Auditors, the Supreme War Council and the Supreme Council of the Navy, and the Dean of the Court of Military Orders, after two years of service; presidents and directors of the Royal Spanish Academy and the other royal academies (History; Fine Arts of San Fernando; Exact, Physical and Natural Sciences; Moral and Political Sciences and Medicine); full academics of the aforementioned corporations occupying the first half of the seniority scale in their corps, first-class general inspectors of the corps of Civil Engineers, Mines and Forests, full-time university professors with at least four years of seniority in their category and practice (and provided that those had an annual income of at least 7,500 Pt from their own property, salaries from jobs that cannot be lost except for legally proven cause, or from retirement, withdrawal or termination); as well as those who had an annual income of 20,000 Pt or were taxpayers with a minimum quota of 4,000 Pt in direct contributions at least two years in advance, as long as they were of the Spanish nobility, had been previously deputies, provincial deputies or mayors in provincial capitals or towns over 20,000 inhabitants, as well as those who had ever held the office of senator before the promulgation of the 1876 Constitution.
