How did the Abbasid empire influence the start and the development of the Umayyad government in Córdoba?

The Abbasid Empire significantly influenced the Umayyad government in Córdoba by providing a model of administration, culture, and governance that the Umayyads adapted in their own context. After the Umayyad caliphate was overthrown in the East, the surviving Umayyad members in Spain established an independent emirate, using Abbasid ideas to create a centralized and sophisticated bureaucratic system. This included the promotion of arts, sciences, and trade, fostering a rich cultural environment that mirrored the flourishing Abbasid capital of Baghdad. Ultimately, the Umayyads in Córdoba blended these influences with local customs, leading to a unique and prosperous society in medieval Spain.
