Central America (Spanish: América Central or Centroamérica) is the predominantly Spanish-speaking central geographic region of the Americas. It is the southernmost, isthmian portion of the North American continent, which connects with South America on the southeast. When considered part of the unified continental model, it is considered a subcontinent. Central America consists of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Panama. Central America attempted to become a unified nation following the model of the United States in 1823, but the union failed and was completely dissolved by 1840.
While most people agreed it would be convenient if a canal was built somewhere in Central America for shipping, the US and the CS could not agree on who would build the canal and who would control it. Each threatened to go to war with the other, if either one tried go ahead with a project to build a canal. US PresidentAlfred Thayer Mahan famously shot down one such CS proposal in Nicaragua.
