Emperor Wu was commonly viewed as a generous and kind, but also wasteful, ruler. His generosity and kindness undermined his rule, as he became overly tolerant of the noble families' (世族or士族, is a political/bureaucratic landlord class from Eastern Han to Tang dynasty) corruption and wastefulness, which drained the people's resources. Further, when Emperor Wu established the Jin Dynasty, he was concerned about his regime's stability, and, believing that the predecessor state, Cao Wei, had been doomed by its failures to empower the princes of the imperial clan, he greatly empowered his uncles, his cousins, and his sons with authority, including independent military authority. This ironically led to the destabilization of the Western Jin, as the princes engaged in an internecine struggle known as the War of the Eight Princes soon after his death, and then the Wu Hu uprisings that nearly destroyed the Western Jin and forced its successor, Eastern Jin relocation to the region south of the Huai River.
