Bolívar began by analyzing what until that time had been considered the historical successes in the struggle for liberty in the Americas. In general terms, it was a balance of force achieved by the patriots in the years from 1810 to 1815. In the middle part of the document are expounded the causes and reasons that justified the "Spanish Americans" in their decision for independence, followed by a call to Europe for it to co-operate in the work to liberate the Latin American peoples. In the third and final part, he speculated and debated on the destiny of Mexico, Central America, New Granada, Venezuela, Río de la Plata, Chile, and Peru. Finally, Bolívar ends his reflections with an imprecation that he would repeat until his death: the necessity for the union of the countries of the Americas. Even though the Carta de Jamaica was nominally addressed to Henry Cullen, it is clear that its fundamental objective was to gain the attention of the most powerful liberal nation of the 19th century, Britain, with the aim that it would decide to involve itself in American independence. However, when Britain finally responded to Bolívar's call, he preferred the help of Haiti.
