Thucydides

Thucydides was an ancient Athenian historian and general, renowned for his "History of the Peloponnesian War." He is often called the "father of scientific history" for his rigorous, evidence-based approach, and the "father of political realism" for his insights into power, fear, and self-interest in international relations. His work remains a foundational text for understanding war, politics, and human nature.
