About José Gustavo Guerrero

Lived 1876 – 1958 (aged 82). José Gustavo Guerrero was a Salvadoran judge, diplomat, lawyer, politician and jurist.

José Gustavo Guerrero (26 June 1876 – 25 October 1958) was a Salvadoran diplomat and jurist who served as the last president of the Permanent Court of International Justice from 1937 to 1946 and the first president of the International Court of Justice from 1946 to 1949. He also served as President of the Assembly of the League of Nations from 1929 to 1930.

Early life

José Gustavo Guerrero was born on 26 June 1876 in San Salvador, El Salvador. During the 1890s, Guerrero attended the University of El Salvador. He and other students were expelled from the university after issuing an open letter to Salvadoran president Rafael Antonio Gutiérrez criticizing his government. Guerrero then moved to Guatemala to attend the San Carlos University of Guatemala where he graduated as a Doctor of Law in 1898. After Guerrero's graduation, he returned to El Salvador where President Tomás Regalado appointed him as his personal secretary.

Diplomatic career

In 1902, Guerrero was appointed as secretary of the Salvadoran embassy to the United States and later as consul of El Salvador to Bordeaux, France. In 1911, he was appointed as El Salvador's extraordinary and plenipotentiary envoy to Rome, Italy. In June 1911, Guerrero attended the coronation of British king George V. In 1912, Guerrero became El Salvador's envoy to Madrid, Spain, and in 1913, he became envoy to Paris, France.

In 1927, Salvadoran president Pío Romero Bosque offered to appoint Guerrero as Minister of Foreign Affairs but Guerrero declined. Guerrero later accepted the appointment due to pressure from his associates to accept the position. Guerrero became Minister of Foreign Affairs on 27 April 1927. As minister, he established the Diplomatic School of El Salvador. On 23 May 1927, Guerrero issued a decree that privatized the University of El Salvador. In 1928, Guerrero led the Salvadoran delegation at the VI Interamerican Conference in Havana, Cuba. He served as Minister of Foreign Affairs until his resignation in 1928 and he returned to Paris to resume his role as extraordinary and plenipotentiary envoy.

In September 1929, Guerrero was elected almost unanimously as the president of the 10th session of the Assembly of the League of Nations. He served until 1930.

Upon the end of his nine-year term, Guerrero was re-elected to a second term.

During the German invasion of the Netherlands in 1940, Guerrero and a group of Dutch officials personally blocked German soldiers from entering the Palace of the Permanent Court of International Justice. Guerrero was the only one of the court's justices to remain in The Hague during the invasion of the Netherlands. Eventually, however, Guerrero left the Netherlands.
