Historical records of empires, such as the Portuguese, British, and Ottoman Empires, reveal a recurring pattern in their life cycles, characterized by alternating periods of ascendancy and decline in international relations. This pattern is grounded in specific pillars of power that contribute significantly to the rise or fall of these empires. Recognizing, developing, and sustaining these pillars enable countries to strengthen their regional and international roles. Notably, the Sultanate of Oman in the nineteenth century was a maritime empire that successfully extended its influence along the Oman Sea to the coasts of East Africa. However, Omani influence has experienced a decline since the twentieth century, as is typical in the natural life cycle of states. This study aims to illuminate the power determinants required to revive the Omani empire. Utilizing a case study methodology, it closely examines historical records and common factors among regionally successful countries, such as Germany, Japan, Türkiye, and South Korea, as a basis for analysis. The study proposes a model for the formulation and implementation of a "grand strategy" by presenting seventeen recommendations tailored to strengthen the Sultanate of Oman's power determinants. These recommendations are derived from an analysis of primary sources on the elements of strength in international relations and grand strategy, with the aim of proposing a roadmap for the Sultanate of Oman to regain its regional and international influence in line with contemporary international covenants.
