Emperor Wu was also known for his extravagance and sensuality, especially after the unification of China; legends boasted of his incredible potency among ten thousand concubines. Emperor Wu was commonly viewed as generous and kind, but also wasteful. His generosity and kindness undermined his rule, as he became overly tolerant of the noble families' (世族 or 士族, a political/bureaucratic landlord class from Eastern Han to Tang dynasty) corruption and wastefulness, which drained the people's resources. 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 "Five Barbarians" uprisings that destroyed the Western Jin and forced its successor, Eastern Jin, to relocate to the region south of the Huai River.
