The Nabataean kingdom, a cornerstone of cultural and historical significance in Jordan, has a rich legacy of inscriptions that offer valuable insights into its history, culture, and administration. This study aims to systematically survey and analyze Nabataean royal inscriptions, exclusively in texts that refer to the deeds and legacies of the royal family members. This helps us understand their role in the kingdom's administration and cultural development. A detailed review informed the analysis of previous scholarship and archeological discoveries. The study's findings are significant, as they demonstrate that ancient Nabataeans' practice of marrying within the royal family was potentially influenced by Egyptian customs and the unique practice of defying kings, as seen in the case of Obodas, the God. Furthermore, it establishes a chronological framework for the reigns of Nabataean monarchs to show the relationships within the royal family and their impact on the kingdom's historical and cultural landscape. This study has yielded different results concerning Kings Rab'l I and II, Queen Šuqylt I, Malichus II, and other royal figures.
