Father of History
Nobody can claim to know history without knowing 𝓗𝓔𝓡𝓞𝓓𝓞𝓣𝓤𝓢. Herodotus is regarded as the father of history.
The 9 volumes
He wrote his 9 volumes of books called Histories. This book deals extensively on the history of the Greco-Persian wars fought in the 5th century BC. Herodotus is believed to have written his voluminous book around 440 BC. Though the book is not what we know as academic history today. But definitely it is the first and most successful endeavor to write history comprehensively. Most of our knowledge about the Persian Empire of that time comes from this book.
The Greek POV
The book is not impartial in its observations as it is written from the point of view POV of the Greeks. Nevertheless the Style, Geography, Events, Descriptions of war etc. dealt in the books are matters worth going through. If you love history you will love Herodotus. The sample below is the history from his book.
"My history hence proceeds to inquire who Cyrus was that overthrew the power of Croesus, and how the Persians be- came masters of Asia. In which narration I shall follow those Persians who do not wish to magnify the actions of Cyrus, but to relate the plain truth"
