Historian is that subject who is in charge of making a recount of events that happened in the past from both a descriptive and a critical point of view. To carry out this task, the historian works with different types of sources whose objective is to provide the appropriate information on facts, processes or phenomena related to the history of Humanity.
It is considered to Herodotus of Halicarnassus as the first historian of Humanity. This intellectual was born and lived in Ancient Greece and worked collecting and telling information about famous events such as battles, wars, reigns of historical figures and other data that made up the Nine Books of History. Although Herodotus resorted to descriptive methods that today seem very basic, his work is undoubtedly the beginning of historical science by offering us an idea of the task of the historian in the face of the facts that he encounters.
Since History is understood as a science, the historian must carry out his task following his own scientific methodologies such as determining his object of study (the section or stage of history to be analyzed), the sources and testimonies with which he will have to carry out such understanding (which can go from material sources to oral sources), and the method of analysis or hypotheses to critique the information obtained. Obviously, the historian always contributes a subjective vision for the understanding of empirical data and that is why History never projects univocal and indisputable truths as it can happen with the natural sciences.
The object of study of History and the historian has varied over the centuries. While the first modern historians based their study on the analysis of the work of the great politicians, thinkers and the military, later currents have sought to complete this analysis with the study of the long-term social, economic and cultural processes that suppose that the History of Humanity is built between everyone.
