El Correo Atlántico was a newspaper first published in Mexico City by its owner and sole editor, Orazio de Attellis Santangelo. It was preceded by a prospectus published on April 1, 1835, and began publication on May 2. Numbers 1 to 16 were published in Mexico City from May 2 to June 24, 1835. Numbers 17 to 41 were published in New Orleans from February 29 to August 15, 1836. In Mexico City the newspaper came out twice a week, in Spanish. In New Orleans, it came out once a week, in Spanish and English.
In Mexico the Correo devoted itself to reporting the most significant events in the various states of the Mexican federation, as related by local newspapers, and in the world. Frequently the reporting was followed by a commentary. Politically, the Correo favored Federalist policies. Because of this and because of its defense of the Texas colonists, on June 24, 1835, its editor was expelled from Mexico. He settled in New Orleans, where he resumed the publication of the Correo Atlántico to counteract the propaganda of La Estrella Mejicana, a periodical first published in New Orleans on February 9, 1836, and subsidized by the Mexican government. The Mexican Federalists in exile in New Orleans committed themselves to the payment of all printing costs of the Correo, while Santangelo undertook the editing and paid for the administrative expenses. However, Santangelo lost their support when the Correo defended and upheld the Texans' decision to secede from Mexico in order to start an independent Republic of Texas. George Fisher and Thomas Toby helped him continue publication.
The last issue of the Correo appeared on August 15, 1836. In an editorial directed to subscribers, Santangelo stated that publication would be suspended for a few weeks but promised that it would be resumed in September with a better format. He was unable to keep his promise because of lack of funds. A complete run of El Correo Atlántico is housed at the American Antiquarian Society in Worcester, Massachusetts.
