How did greek historians change the way history was written by.

During Classical Antiquity, the ancient Greeks developed the discipline that we today know as history. Ancient Greek Historians composed their works by interviewing eyewitnesses, studying documents, and drawing on earlier historical research. Some ancient Greek Historians even actively participated in or witnessed the events they described themselves. With the passage of time, the writings of many ancient Greek Historians have been lost; it exists only as fragments, quotations, or references in later works. Regardless of whether or not their work has survived in its entirety, the Ancient Greek Historians shaped our understanding of Classical Antiquity and the study of history.
