Miguel Primo de Rivera, 2nd Marquis of Estella

Miguel Primo de Rivera y Orbaneja, 2nd Marquis of Estella, GE (8 January 1870 – 16 March 1930), was a Spanish dictator and military officer who ruled as prime minister of Spain from 1923 to 1930 during the last years of the Bourbon Restoration.

He was born into a landowning family of Andalusian aristocrats. He met his baptism by fire in October 1893 in Cabrerizas Altas during the so-called Margallo War. He moved up the military ladder, promoted to brigadier general (1911), division general (1914), and lieutenant general (1919). He went on to serve as administrator of the Valencia, Madrid, and Barcelona military regions, distinguishing himself as a voice in favour of military withdrawal from Africa.

During the crisis of the Restoration regime, specifically upon political turmoil in the wake of setbacks in the Rif War and the ensuing spillover of the enquiries of the Picasso file, Primo de Rivera staged a military coup d'état on 13 September 1923 with help from a clique of Africanist generals close to King Alfonso XIII. The coup enjoyed the acquiescence of the monarch, and Primo de Rivera was ensuingly tasked to form a government. He thereby proceeded to suspend the 1876 constitution and establish martial law.

His dictatorial rule was marked by authoritarian nationalism and populism. Primo de Rivera initially said he would rule for only 90 days; however, he chose to remain in power, heading a military directorate. In December 1925, after the Alhucemas landing ended Rifian anti-colonial resistance, he installed the Civil Directory. From 1927 a policy of public spending on infrastructures was pursued and state monopolies such as oil company Campsa were created. Once economic tailwinds diminished, he lost the support of most of his generals, and he was forced to resign in January 1930 amid increasing inflation and civic unrest, dying abroad two months later.

Some of his children, such as José Antonio and Pilar, went on to become Falangist political leaders.
