José Sanjurjo Sacanell (Pamplona, 1872 - Estoril, Portugal, July 20, 1936) Marquess of the Rif and general, was a Spanish Army Officer who was one of the chief conspirators of the military uprising that led to the Spanish Civil War.

He served in Cuba (1896) and in several campaigns in Morocco (1909), among them the reconquest of the lost territory in Melilla after the Disaster of Annual (1921). In 1922, in the front of the separate military command of Larache, he investigated the cases of corruption in Intendance and armed intervention. He was High Commissioner of Spain in Morocco and reached the rank of lieutenant general. In 1925 he participated in the disembarkation of Alhucemas. In 1927, with the completion of the War of the Rif King Alfonso XIII awarded him on March 28, 1931 the Gran Cruz de Carlos III. In 1928 he was made chief of a main directorate of the Civil Guard.

After the elections of April 1931 he was first that was put before to the orders of the republican Revolutionary Committee upon the proclamation of the Republic, reason why with the influence that he had with his position as chief of a main directorate of the Civil Guard he laid the way to the restoration of the Republic. He faced Manuel Azaña over his military policy and was replaced in his position by General Miguel Cabanellas. He was demoted by Azaña to chief of the customs officers in 1932 because of the events of Castilblanco and Arnedo. This confrontation with the government along with the autonomy measures and the military reforms of Azaña, led him to join with some carlists of Fal Conde and the conde de Rodezno and other military officers in a revolt in Seville on August 10, 1932. He achieved initial success in Seville but absolute failure in Madrid in his revolt known as the sanjurjada. He clarified that he rose against the government and not against the republican regime. Against this one revolt it was Azaña that transferred for the first time African Regular troops to the peninsula to fight a rebellion. He tried to flee to Portugal but in Huelva he decided to give himself up. He was condemned to death, a sentence which was later commuted to life imprisonment in the penitentiary of the Dueso. In March 1934 he was granted amnesty by the Lerroux government and went into exile in Estoril, Portugal. When on May 10, 1936 Niceto Alcalá Zamora was replaced as President of the Republic by Azaña, Sanjurjo, along with Generals Emilio Mola, Francisco Franco and Gonzalo Queipo de Llano started plotting to overthrow the leftist Popular Front government. This led to the National Rising, of which he was the chief organizer and main ringleader, which started the Spanish Civil War on July 17, 1936.

Sanjurjo died in a plane crash when he attempted to return to Spain on July 20, 1936 in an airplane piloted by Antonio Ansaldo. One of the main reasons was heavy carriage, although pilot warned him that bags were too heavy Sanjurjo answered him: I need to wear proper clothes as the new caudillo of Spain. When Mola also died in an airplane accident, Franco was left as the effective leader of the Nationalist cause. This led to rumours that Franco had instigated the deaths of his two rivals, but no evidence has been produced to support this allegation.
