Traditional methods of studying the past have always given greater importance to nationalistic, religious and moral interests, which subordinated the historical fact to the point of view of the system. This is the way we have been educated.

The time has come to simplify and show respect for our ancestors, striving to know what really happened in the past, and not just what they pretend to inform us. After so many years studying History, I came to the conclusion that the best system of study is through an impartial, objective Chronology, which limits itself to place each event in its exact place in time, revealing History without manipulations.

This Chronology contains not only purely political facts, such as the founding of cities, the birth of kingdoms and empires, scientific and geographical discoveries, natural disasters and epidemics, but also includes information on the most diverse fields of human activity: chemistry, astronomy, geography, mathematics, etc. At the same time, the chronology is complemented by data that do not belong to a specific date, but to a whole era, such as generalities of each society, curiosities, customs, the religion of each civilization, inventions or discoveries that cannot be placed in an exact date, etc.

The result of all this is one of the most complete chronologies available, periodically updated with the latest archaeological and scientific discoveries, and which transforms the reader into an eyewitness of the past, understanding the relationship of events geographically distant from each other, but closely connected in time and influencing unexpected consequences. This is something that traditional history has generally neglected when it was not usable.

A work of this magnitude could not be published in a single book, so I have divided it into several collections, the Spanish originals of which are being translated into French, English, Italian and Portuguese. The chronology runs year by year, as far as possible, from prehistory to the present day.

For those who prefer a deeper and more detailed study, I have prepared a second chronology, day by day, which for the time being runs from 1789 to 1946, divided into five collections. .
