Why is Herodotus called “The Father of History”?

Herodotus was a Greek historian who was born in Halicarnassus in the Persian Empire (modern-day Bodrum, Turkey) and lived in the fifth century BC (c. 484–c. 425 BC), a contemporary of Thucydides, Socrates, and Euripides. He is often referred to as “The Father of History”, a title first conferred by Cicero; he was the first historian known to have broken from Homeric tradition to treat historical subjects as a method of investigation—specifically, by collecting his materials systematically and critically, and then arranging them into a historiographic narrative.

“2,500 years ago, the writing of history as we know it didn’t exist. The past was recorded as a list of events, with little explanation for their causes beyond accepting things as the will of the gods. Herodotus wanted a deeper understanding, so he took a new approach: looking at events from both sides to understand the reasons for them. Mark Robinson explains how “history” came into being.”

The Histories is the only work which he is known to have produced, a record of his “inquiry” on the origins of the Greco-Persian Wars; it primarily deals with the lives of Croesus, Cyrus, Cambyses, Smerdis, Darius, and Xerxes and the battles of Marathon, Thermopylae, Artemisium, Salamis, Plataea, and Mycale; however, its many cultural, ethnographical, geographical, historiographical, and other digressions form a defining and essential part of the Histories and contain a wealth of information. Some of his stories are fanciful and others inaccurate; yet he states that he is reporting only what he was told; a sizable portion of the information he provided was later confirmed by historians and archaeologists. Despite Herodotus’s historical significance, little is known of his personal life. -https://en.wikipedia.org/wiki/Herodotus
