Prof  Hernandez' s monumental work <i>The History of Central America</i> covers everything about the region from the origin of the Mesoamerican period to the end of the Cold War  While the book has several informative maps and charts, many of the chapters spend less time describing facts and more time explaining Prof  Hernandez' s theories  Indeed, the last two chapters consist exclusively of his exposition of theory of the role of Central America in post WWII world politics
Ttherefore, properly speaking, this book is not a history book
History as a discipline is concerned only with historical facts, not with the theoretical explanations of those facts.
