Óscar R. Benavides emerged as a significant military and political figure in early 20th-century Peru, twice ascending to the presidency during periods of intense national upheaval. Born in Lima in 1876, he transitioned from a career as a field marshal and diplomat into an authoritarian executive, ultimately shaping the country's political trajectory through two distinct terms.
Military Formation and Early Service
Benavides entered the Military School of Lima following his studies at the College of Our Lady of Guadalupe. By 1906, he had graduated with distinction from the Military Academy. His early training included time in France, where he earned the Legion of Honour. He rose through the ranks, achieving the position of captain by 1901 and later becoming a field marshal.

In 1911, Benavides commanded forces during the Battle of La Pedrera against Colombia. After an arduous march through the Andean range to the Amazonian jungle, his troops secured a victory at the Caquetá River. Despite this success, the campaign resulted in significant personnel losses due to yellow fever and beriberi, experiences that Benavides later noted with profound personal dismay.
First Presidency and Political Turmoil
Following the 1914 deposition of President Guillermo Billinghurst, Benavides assumed the role of Provisional President. His 18-month tenure focused on restoring political stability before he facilitated a transition of power to José Pardo y Barreda in 1915. During subsequent years, he served as a diplomat in Europe, though he faced political imprisonment under the administration of Augusto B. Leguía.
Authoritarian Tenure and Later Years
Benavides returned to domestic leadership as President of Peru from 1933 to 1939. His second term was characterized by authoritarian governance, notably involving the annulment of the 1936 general election when his preferred successor appeared likely to lose. He remained active in government service until his later years, receiving the Grand Cross of the Cross of Military Merit in 1941.
