Session of the 1st Congress of the Confederación de Trabajadores Cubanos [CTC], Cuba's largest umbrella syndicate of labor unions, held between November 18 and 25, 1959, in Havana. Approximately 3,000 workers' delegates attended the congress whose primary task was the election of a new governing board, free of the mujalistas, or allies of Eusebio Mujal, Batista's main representative who had previously controlled the unions. Fidel's inaugural address to the delegates is clearly documented in Print 30. These images appear to document Fidel Castro's subsequent address to the workers' delegates that occurred after a great deal of strife erupted over the election of a slate of candidates to the governing board that included former members of the mujalista-Batista alliance who were active Communists. Conflict culminated on the 23rd of November, one of the final days of the congress. Fidel returned to the congress in order to urge that the "unity" slate of candidates, including the Communists, as well as David Salvador, the candidate his government backed for the position of Secretary General, be elected. On stage, directly behind Fidel, sit a number of delegates clearly allied to the 26th of July Movement, as is clear from their use of the revolutionary militiamen's uniforms. Fidel Castro's speech to the delegates was also being televised, as is clear from the top three rows of frames. See also Print 30.
