During the period of Mahdi (775-785), who was the third caliph of the Abbasid state, many remarkable positive developments were seen within the borders of the Abbasid state. Naturally, the person who ignited these positive and qualified developments was the Mahdi due to his position. Unlike the strict and harsh policy of his father Mansur (754-775), the Mahdi took care to follow an extremely moderate and soft policy towards those living under the roof of the state. Caliph Mahdi, who made great efforts not only in the political sense but also in the zoning of the state, reaped the fruits of these efforts, so to speak, concretely. In addition, the Mahdi, who attaches great importance to the establishment of justice, established the justice mechanism within the state. In this way, it not only provided a real institutionalization based on merit as a result of the elimination of injustice in the institutions of the state, but also prevented the environment of turmoil that could arise due to injustice within the state. However, it should be stated here that the driving force of this administrative or political attitude of Mahdi in terms of administration, or in other words, the most important cause, is some important advice and advice that his father Mansûr suggested to him in his testament. In this study, we will discuss how effective or not the advice given to him by his father, Mansûr's, is in the Mahdi's politics.
