On October 3, 1968 General Juan Velasco Alvarado, commander of Peru's armed forces, overthrew the elected president Fernando Belaunde Terry in a bloodless pre-dawn coup, dissolved Congress, and installed a leftist, nationalist military government that ruled Peru for twelve years. Belaunde's administration had been paralyzed by feuds with an opposition-dominated Congress, but the immediate spark was the La Brea y Parinas oil scandal: a controversial August 1968 settlement with the American-owned International Petroleum Company, followed by the revelation that a page (the famous Page 11) fixing crude prices was missing from the contract, ignited nationalist outrage and accusations of a sellout to foreign interests. Before dawn on October 3, army tanks rolled into Lima and seized the government palace, Congress, and broadcast stations; soldiers under Colonel Enrique Gallegos took Belaunde from the palace and, on Velasco's orders, flew him into exile in Argentina.
Velasco proclaimed the Revolutionary Government of the Armed Forces and, six days later, expropriated the IPC oil fields at Talara. Belaunde spent years teaching in Argentina and the United States before returning and winning the presidency again in 1980.

General Juan Velasco Alvarado seized power on October 3, 1968 in a bloodless military coup, deposing the democratically elected administration of Fernando Belaunde, under which he served as Commander of the Armed Forces, and President Belaunde was sent into exile; the coup was sparked by the dispute over the La Brea y Parinas oil fields and the missing Page 11 of the IPC contract, and the leaders named their administration the Revolutionary Government of the Armed Forces.

At dawn on October 3, 1968 three army tanks arrived at the main square, the army broke the gates and entered the Government Palace, and a group of soldiers under Commander Enrique Gallegos drove Belaunde to the Armored Division Headquarters while other tanks took Congress, the party headquarters, National Radio, the Interior Ministry, and TV stations; at 8 am Belaunde was forced onto a plane and deported to Ezeiza International Airport in Argentina.

The 1968 Peruvian coup took place amid serious arguments between President Belaunde and an APRA-UNO dominated Congress that censored several cabinets, and the La Brea y Parinas scandal, when a key eleventh page of the IPC contract was found missing, sparked a national scandal, leading the armed forces to seize absolute power, close Congress, and briefly incarcerate almost all its members.
On October 3, 1968 General Velasco led a bloodless coup by the armed forces, dissolving Congress, exiling Belaunde to Argentina, and establishing the Revolutionary Government of the Armed Forces, which promptly annulled the IPC accord and expropriated its assets on October 9; Belaunde later resided in the United States, teaching architecture, until his return in 1976 and his re-election as president in 1980.

Editorial Note
Fate coding: Belaunde was deported to Argentina, matching the dataset's exiled fate; he was not physically harmed and returned to win the presidency again in 1980, a notable democratic restoration. Significance flagged by sources: unlike most Latin American military regimes of the era, Velasco's Revolutionary Government of the Armed Forces was left-leaning and nationalist, expropriating the US-owned IPC oil fields on October 9 and later undertaking agrarian reform, souring relations with the United States under the Hickenlooper Amendment. Arc note: Velasco was himself deposed in the August 1975 Tacnazo by his prime minister Morales Bermudez, a separate later dataset event.
