Why did political fragmentation after the 10th century create opportunities for Arabic poets?

Following the 10th century, the political fragmentation of the Islamic world into various local dominions—such as the Abbasid, Fatimid, and Umayyad caliphates—ironically created significant opportunities for poets.12

As the central authority splintered, a continuing series of petty dynasties emerged, each seeking to establish its own prestige and legitimacy. This competition fostered a high demand for court patronage, which served as the primary means of support for poets and scholars. Rulers and governors frequently commissioned panegyrics for state occasions to celebrate their own achievements and the glories of their domains. Consequently, poets found numerous venues to recite their work and receive rewards, as the existence of multiple competing courts provided a wider array of potential patrons than a single, unified empire might have offered.123
