Who was the greatest historian of all time?

Determining the greatest historian of all time is subjective and often depends on personal preference and cultural context. Many consider Thucydides, known for his critical analysis of the Peloponnesian War, as a foundational figure in historiography. Others might argue for Herodotus, often called the "Father of History," for his narrative style and broad coverage of the ancient world. In modern contexts, historians like Edward Gibbon, known for "The History of the Decline and Fall of the Roman Empire," have also left a lasting impact.
