As an introduction to several papers from the "Igbo-Ukwu at 50" symposium in September 2021, this article reviews the history of the discoveries and excavations, the early debates over chronology, and more recent research contributions that refine and expand our understanding of this unique site. These include new field investigations at Igbo Ukwu, new radiocarbon dates, textile analysis, chemical analyses of glass, and carnelian beads plus lead isotope analyses of leaded bronze and copper artifacts to identify source areas, and metallographic studies.
