Nimi a Nzima
Nimi a Nzima is named in Kongo oral tradition as the last ruler of Mpemba Kasi, a Bantu kingdom in the Vungu lands that was vast but not strong, remembered as the Mother of Kongo.
He married Lukeni lua Nsanze, daughter of Nsaku Lau, chief of the northern kingdom of Mbata, and the match bound the two states together. Around 1375 Mpemba Kasi and Mbata merged to form the Kingdom of Kongo.
Their son Lukeni lua Nimi is traditionally said to have conquered the country around Mbanza Kongo and become its first king. These traditions were written down in the seventeenth century.
