The Luba Empire, established in the Upemba Depression (modern-day DR Congo), emerged from a power struggle between the tyrannical king Nkongolo and his successor Kalala Ilunga. Under Kalala's rule, the empire developed a sophisticated sociopolitical structure combining centralized feudalism with local autonomy. The empire featured divine kingship (Mulopwe), a robust taxation system, and the Bambudye lodge which served as a check on royal power. Its spiritual foundation centered on a trinity-based cosmology connecting the physical and spiritual worlds through rituals like Kasala poetry and Kifwebe masks. The empire's prosperity, built on trade monopolies of resources like copper and salt, declined in the late 18th century due to Belgian colonization, though its cultural and linguistic legacy persists in modern DR Congo.
