Sun Tzu was a Chinese general, military strategist, and philosopher credited with writing 'The Art of War.' This ancient text is considered the most influential work on military strategy and has significantly impacted both Eastern and Western military thinking, business tactics, and legal strategy. Sun Tzu emphasized that 'all warfare is based on deception' and argued that the greatest victory is that which requires no battle. His philosophy prioritizes intelligence, flexibility, and understanding the psychology of the enemy over brute force. He introduced concepts such as the importance of terrain, the use of spies, and the necessity of discipline. While some historians debate his existence as a single individual, the text attributed to him remains a core curriculum for military academies worldwide, demonstrating the timelessness of his insights into conflict resolution and leadership.
