Sergio Carbó (born 1891 - April 18, 1971) was a prominent Conservative journalist[1] and leader of the Cuban Revolutionary party.

[10] In August 1933, an army revolt in Havana forced President Machado to flee Cuba and he was succeeded by Carlos Manuel de Céspedes y Quesada.

[13] An executive committee of five men including Carbó, Dr. Ramón Grau, José Irisarri, Dr. Guillermo Portela, and Porfirio Franca replaced the Céspedes cabinet as Cuba's governmental leaders.

Within a week, Dr. Ramón Grau was promoted to president, replacing the Pentarchy with the One Hundred Days Government on September 10, 1933.

[16] On November 13, 1933, Carbó accused the United States ambassador to Cuba, Sumner Welles, of supporting an attempted uprising against President Grau's regime and asked that he be removed from his post.
