The Igbo Ukwu people had some of the most successful metal working art as early as the 9th century ("Oldnaija," 2018). Three sites were excavated, showing hundreds of ritual vessels and regalia castings of bronze or leaded bronze, which is some of the most inventive and technologically advanced bronzes ever made ("Oldnaija," 2018). These people were some of the earliest Smithers of copper in West Africa, using skills like hammering, bending, twisting, and incising ("Oldnaija," 2018). Even so, evidence shows that their metalwork was limited because they were not familiar with certain techniques such as raising, soldering, riveting, and wire making; while, these techniques were practiced elsewhere throughout the continent ("Oldnaija," 2018). The Igbo Ukwu people were some of the most talented and intelligent people. Other bronze work did not develop until several centuries later in other parts of Nigeria ("Oldnaija," 2018). This shows how advanced these people were.
