Castaneda became
President of El Salvador on 1 March 1945.
Manuel Adriano Vilanova was his
vice president. Castaneda appointed a cabinet consisting of
Arturo Argüello Loucel as
Minister of Foreign Relations;
Efraín Jovel as Minister of the Interior;
Carlos Alberto Guirola as
Minister of the Economy; and
Ranulfo Castro as
Minister of Culture. Castaneda served as
Minister of National Defense in March 1945 before appointing General
Mauro Espínola Castro. Many of Castaneda's political appointments served under Martínez, and contemporary commentators viewed Castaneda's presidency as merely a continuation of Martínez's presidency. Castaneda met Guatemalan president
Juan José Arévalo at the
El Salvador–Guatemala border on 17 May 1945 and signed a pact that declared that both countries intended to form a political union. On 10 June, the
Salvadoran Air Force attempted a coup against Castaneda and bombed the headquarters of the
National Police. The coup failed and its leaders were exiled. After the coup attempt, Castaneda placed El Salvador under a "state of siege" that lasted for the rest of his presidency. During Castaneda's presidency, he established the holidays of Telegraphist Day, Soldier's Day, and
Mother's Day on 27 April, 7 May, and 10 May, respectively. No
executions were carried out during his presidency. Castaneda was accused of
corruption when he allegedly stole from state revenues from selling coffee. In October 1945, a newspaper reported that Guirola had resigned as Minister of the Economy when he had not done so. Castaneda offered to appoint Guirola as Minister of Foreign Relations but Guirola resigned in protest. Argüello resigned as Minister of Foreign Relations when he learned that Castaneda offered Guirola his office. Castaneda's cabinet collapsed when more ministers resigned. It took one month for Castaneda to appoint new ministers. (right) In January 1946, Castaneda's government loosened restrictions on labor unions. He also reestablished the Ministry of Labor, but workers were dissatisfied with working conditions and wages and held strikes in August and September. The ministry declared the strikes to be illegal. In response, workers held a strike at
Plaza Libertad in
San Salvador; security forces shot at the crowd, killing some strikers. Bakers held a strike in October, but this strike was also suppressed. By the end of 1946, the country's labor unions had gone underground. == Overthrow ==
