During the long reign of Notouom, which lasted until 1641, he worked to increase the population of Bandjoun by buying all that he could acquire (cattle, food, valuables, and slaves whom he freed to integrate them into his kingdom). It was under his royal magistracy that the name "Bandjoun" originated with the term "Pa Djo" meaning "those who buy". Very expansionary, he made all the smaller heads of villages vassals and modernised his kingdom administratively and militarily. He created administrative districts called "Djie".
