Kongo's Disintegration
As a result of all these wars the kingdom of the Loango in the north gained independence from Kongo. Also new kingdoms came to existence of which the Téké was the most important, ruling over a large area encompassing present-day Brazzaville and Kinshasa. Portugal's position in Europe suffered a major change in 1580 when the Kingdoms of Spain and Portugal were united by a personal union under King Philip, creating the Iberian Union which lasted until 1640. This resulted in a diminished role for Portugal in African affairs, including the area around the mouth of the Congo River. The Kingdom of Kongo was reduced to a small enclave in the north of Angola with King Pedro V in 1888 finally accepting to become a vassal of the Portuguese. The Portuguese abolished the kingdom after the revolt of the Kongolese in 1914.
