Anniversary of Reza Shah's death (first Pahlavi ruler), Mordad 4. Reza Shah Pahlavi, founder of the Pahlavi dynasty and its first monarch, died on Mordad 4, 1323, in Johannesburg, South Africa. Following the Allied occupation of Iran during World War II and his abdication in Shahrivar 1320, Reza Shah was forced to leave the country and live in exile. His exile took him through several countries, ending in South Africa where he passed away. Reza Shah's death marked a turning point in Iran's modern history, bringing significant political and social consequences. With his passing, Mohammad Reza Pahlavi became the second monarch of the dynasty, and the country's political landscape entered a new phase. This event has remained a subject of interest among historians and those studying Iran's contemporary era. Since 1324, the anniversary of Reza Shah's death has been recognized in the Jalali calendar as a historical observance to reflect on his role and influence in Iran's modern developments.
