The soldiers, due to the scarcity of livelihoods and salaries, were constantly declaring riots against the caliphs, the Buyid princes, their ministers, and even their leaders due to the intensification of financial distress and the rise in prices. Then their riots stopped when money was distributed to them. The conflict also occurred between the soldiers themselves, especially between the Daylam and the Turks, who were considered two prominent elements in the Buyid army, and the focus of their conflict was the policy of discrimination followed by the Buyid princes by bringing one group closer together and alienating others. The princes themselves paid the price for this policy, as their army was weak and could not withstand the real challenges facing the state. The research was divided into an introduction and three chapters. The introduction included the emergence of the Buyid era, while the first section included the struggle of the political soldiers with the caliphs, and the second section dealt with the struggle of the political soldiers with the Buyid princes. The third section included the conflict between the soldiers among themselves.
