The king of Kongo also held several kingdoms in at least nominal vassalage. These included the kingdoms of Kakongo, Ngoyo and Vungu to the north of Kongo. The royal titles, first elaborated by Afonso in 1512, styled the ruler as "King of Kongo and Lord of the Mbundus" and later titles listed a number of other counties over which he also ruled as "king". The Mbundu kingdoms included Ndongo (sometimes erroneously mentioned as "Angola"), Kisama and Matamba. All of these kingdoms were south of Kongo and much farther from the king's cultural influence than the northern kingdoms. Still later eastern kingdoms such as Kongo dia Nlaza were named in the ruler's titles as well.
