Álvaro IX Mpanzu a Ntivila was a ruler of the Kingdom of Kongo during its civil war period.
Afonso II had been forced off the throne by the House of Kinlaza, and had set up Kimpanzu's powerbase in the mountainous Nkondo.
[2] He fled to Lemba to start continue his reign and to fight against Kimpanzu rule.
However even amongst the nobles of Kimpanzu were starting to resent the intervention of Soyo in Kongo affairs.
In 1670, Álvaro IX was overthrown by Rafael I who preceded him as a more anti-Soyo king, who ended Soyo intervention in the kingdom.
