What is the main difference between history classes in the u. s and mexico

In U.S, History is a general branch of social studies that is taught in the upper levels of elementary school and in middle school. In middle school and high school, however, it is typically broken down into two different categories: world history and U.S. history.  

In Mexico, History is a subject in permanent redefinition, whose approach varies according to the interpretation that historians make about the facts

the former currency of el salvador who honored an american sailor was:

answer: christopher columbus

the 200 (doscientos colones) was the currency that showed a picture of christopher columbus in front of the bill with a ship - this currency ran from 1892-2001, it was then replaced with the u.s. dollar.
