The Battle of Kadesh fought between the Hittites and Egyptians in Syria is one of the biggest chariot battles in ancient Near Eastern history. Previous research has shown that the significance of the Battle of Kadesh is derived predominately from a tactical and strategic level. This dissertation introduces the idea that although this is a tactical battle, its overall importance comes from applying a holistic approach, in particular, investigating the causes and consequences, alongside the battle. By extending prior work on tactics and strategy to include an identified cause, the Zannanza Affair, and the consequences, the Treaty of Kadesh and the Royal Marriages it makes allowances for a wider evaluation of the battle. Attention is paid to textual, iconographical and archaeological sources to gain a better understanding of the battle. The findings provide support for the argument that the murder of the Hittite prince in the Zannanza Affair led to crucial military innovations and operational changes adopted by the Hittites and Egyptians, which impacted how they fought on the battlefield. While a considerable amount of research has been done on the Hittite and Egyptian military organisations, the role of the elite units on the battlefield has largely not been explored. The Treaty of Kadesh and the Royal Marriages were a critical turning point in Hittite-Egyptian relations offering a strong alliance and unprecedented peace in the ancient Near East. Traditionally, the Battle of Kadesh has been viewed as a tactical battle. However, for further advances, the contribution of this study prompts a rethinking of the latter by placing the operational details of the battle in a broader context encouraging new research on the social, cultural and political aspects, which is crucial for the understanding of the importance of the Battle of Kadesh, on and off the battlefield. / Biblical and Ancient Studies / M.
