Spanish general who served briefly as prime minister (January 1930–February 1931) before the establishment of the Second Republic.

Berenguer entered the army in 1889, served in Cuba and Morocco, and was promoted to general in 1909. He was minister of war in 1918 when, after a long interval, the army began to express its political views. He then served as high commissioner in Morocco, but he was held responsible for the disastrous defeat at Annual (Anwal) in 1921 and was removed from active service. In 1924 he was appointed head of King Alfonso XIII's military household. When the dictatorship of Miguel Primo de Rivera (Primo de Rivera, Miguel) came to an end, Alfonso made Berenguer prime minister, hoping that he would be able to prepare for a return to constitutional rule. But the political parties blamed the king for permitting the dictatorship, and the republicans, socialists, and Catalan left demanded that he abdicate. Berenguer attempted to resolve the conflict from January to December 1930 but without success. Then there occurred a small military revolt at Jaca. Berenguer resigned on February 14, 1931, but served as minister of war under his successor, Admiral Juan Bautista Aznar-Cabañas. After the municipal elections of April 1931 showed the republicans to be in the majority in the main cities, Alfonso XIII left the country. The republicans assumed power, and Berenguer was imprisoned during most of the Second Republic. In 1946 he published a defense of his administration.
