What happened when perisian armies moved into Baghdad in 945?

In 945, Persian armies, specifically the Buyids, captured Baghdad, marking a significant shift in power in the region. The Buyids, a Shiite dynasty, took control of the Abbasid Caliphate, effectively reducing the Caliph's authority and establishing a period of de facto rule over the city. This event led to a fragmentation of political power and the rise of regional dynasties, contributing to the decline of the Abbasid influence in the Islamic world. The Buyids also promoted Persian culture and administration, further altering the socio-political landscape of Baghdad.
