[3][4] Voting for the Cortes was on the basis of universal manhood suffrage, which comprised all national males over 25 years of age, having at least a two-year residency in a municipality and in full enjoyment of their civil rights.

Amendments to the electoral law in 1907 introduced compulsory voting, though those older than 70, the clergy, first instance judges and public notaries were exempt from this obligation.

The remaining 30 were allocated to special districts comprising a number of institutions, electing one seat each—the archdioceses of Burgos, Granada, Santiago de Compostela, Seville, Tarragona, Toledo, Valencia, Valladolid and Zaragoza; the Royal Spanish Academy; the royal academies of History, Fine Arts of San Fernando, Exact and Natural Sciences, Moral and Political Sciences and Medicine; the universities of Madrid, Barcelona, Granada, Oviedo, Salamanca, Santiago, Seville, Valencia, Valladolid and Zaragoza; and the economic societies of Friends of the Country from Madrid, Barcelona, León, Seville and Valencia.

The Cortes were officially dissolved on 14 April 1910, with the dissolution decree setting the election dates for 8 May (for the Congress) and 22 May 1910 (for the Senate) and scheduling for both chambers to reconvene on 15 June.

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.
