One of the significant developments of the Naseri era, which contributed to the expansion of relations and politico-religious convergence between Iran and the Ottoman Empire, was the travels of the Shah, princes, and high-ranking Iranian political officials to Ottoman territories. These visits were undertaken for the Hajj pilgrimage, visiting the holy shrines (Atabat), or tourism, and involved meetings and dialogues with the Sultan and high-level Ottoman officials. Utilizing a descriptive-analytical approach, the present study examines the context, circumstances, and outcomes of Naser al-Din Shah's two journeys to the Ottoman Empire. The study's fundamental research question is: What were the precedents and objectives of the Qajar monarch's travels to the Ottoman realm, and what implications did these visits have for Iran-Ottoman relations? According to the research findings, the most significant outcomes of these travels include: establishing a foundation for negotiation and dialogue; reducing religious hostility and conflict; achieving a relative stabilization of tense bilateral relations; the respectful treatment and formal reception protocols extended to the Shah of Iran by Ottoman officials; Naser al-Din Shah's negotiations with the Sultan, high-ranking Ottoman dignitaries, and foreign ambassadors residing in Istanbul; the Shah's exposure to new manifestations of civilization and culture; and laying the groundwork for potential Islamic political and religious unity and convergence between Iran and the Ottoman Empire.
