El circo (song)
The lyrics describe two brothers, "Carlos" and "Raúl" (in reference to Carlos Salinas de Gortari, president of Mexico from 1988 and 1994, and his brother Raúl Salinas de Gortari), who form a "circus" (a drug cartel) and get rid of the other "circuses" in the country. After the brothers get wealthy, Raúl makes Carlos' money disappear (a reference to the Mexican peso crisis) and their circus ends. Raúl is jailed, while Carlos leaves the country, and the people are finally at peace, unless another circus arrives and the story repeats itself.
History of the Catholic Church in Mexico
When Northern caudillo Plutarco Elías Calles was elected president in 1924, he was determined to enforce the constitutional provisions on religion. Calles was a known anticlerical, more fanatical in his ideology than many other Constitutionalists, perhaps because he felt the sting of his status as a natural son of parents who had not married in the Church, nor had they bothered to baptize him; his father had abandoned him and his mother died when he was three. Some scholars view his illegitimacy as fundamentally shaping his attitude toward religion and the Catholic Church.
