Francisco Serrano Domínguez, 1st Duke of la Torre, Grandee of Spain, Count of San Antonio (17 December 1810 – 25 November 1885) was a Spanish marshal and statesman.

Serrano was born on 17 December 1810 in the Isla de León (current day San Fernando),[1] in the Bay of Cádiz.

[2] As aide-de-camp of Espoz y Mina, then under the orders of generals Córdova and Espartero, in the armies of Queen Isabella, Serrano took such an active part in the First Carlist War from 1834 to 1839, that he rose from the rank of captain to that of brigadier-general.

[2] On 29 September 1850 in Madrid, Serrano married his first cousin, Antonia Domínguez y Borrell, Guevara y Lemus, 2nd Countess of San Antonio,[n. 1] with whom he had five children.

On landing he signed the manifesto of the revolution with Prim, Topete, Sagasta, Martos and others, and accepted the command of the revolutionary army.

In February 1869, he convoked the Cortes Constituyentes; he was appointed successively as president of the executive, Prime Minister of Spain, and Regent from 3 October 1868 to 18 June 1869.

[2] As soon as Amadeus reached Madrid, after the death of Prim, Serrano consented to form a coalition cabinet, which lasted only a few months.

On the eve of his coup d'état of 3 January 1874 that sought to thwart the Federal Republic, the leading instigator, the General Manuel Pavía, sent for Serrano to take the leadership.

During the eleven months he remained in office, Serrano devoted his attention chiefly to the reorganization of finance, the renewal of relations with American and European powers, and the suppression of revolt.

He returned to Madrid in 1876, attended palace receptions, took his seat as a marshal in the senate, and flirted politically with Sagasta and his party in 1881.

[2] He finally gave his support to the formation of a dynastic Left with a democratic program defended by his nephew, General José López Domínguez.
