He was appointed
Governor of Monagas state (1949–1951) under the
military junta set up after the
1948 Venezuelan coup d'état. After the restoration of democracy in 1958, he joined the
Democratic Republican Union (URD). and appeared likely to gain the URD presidential nomination for the 1968 election. In response URD leader
Jóvito Villalba, who wanted to be re-nominated, had Ugarte Pelayo suspended from the URD in April 1966. The vote of the URD National Directorate fell 16 to 12, and "it soon became evident that if Ugarte left the party over his suspension, he would take with him the twelve members of the National Directorate who had backed him against Villalba, eight congressmen, and at least ten state organizations." Ugarte Pelayo announced the creation of a new party, Movimiento Demócrata Independiente, and was found dead in his home on 19 May by reporters he had invited for a press conference, an apparent suicide. A street in
Maturín,
Avenida Alirio Ugarte Pelayo, is named for him. == Books ==
