The historical development of the Kingdom of Congo: it was colonized by Portugal for a long time.

According to oral legend, the ancestors of the Bakongo people established their country hundreds of years before the invasion of Portuguese colonists, and Minnie Luki 14 century unified the scattered tribes into a kingdom. 1483 King N'Singa Cuvu, whom the Portuguese first met, was the fifth or eighth king of this country, when the central government of the kingdom was quite consolidated. Alfonso I succeeded to the throne in 1506 (reigned in 1506- 1543) and believed in Catholicism. With the help of the Portuguese, he put down the resistance of various tribes in China, and made Portuguese forces gradually penetrate into Congo.

1569, the lower reaches of the Congo River broke out. The rebels took Portuguese colonists, kings, businessmen and leaders as enemies and drove King Alvaro I out of the capital. Portuguese colonists suppressed the uprising. After the restoration, Alvaro I actually became a puppet of Portuguese colonists, and the centralization of the kingdom was greatly weakened. Garcia II ascended the throne in 164 1. He used the contradiction between Portuguese and Dutch colonists to rectify internal affairs and restore the national situation. However, in 1648, Portuguese colonists made a comeback and retaliated against Congo, demanding not only compensation for land cession, but also the right to explore mineral deposits, which was rejected by the King of Congo. 1665, the Portuguese colonial army invaded Congo, and King Antonio I died in the Battle of Ambira, and the royal army collapsed. However, the Congolese people rose up and attacked Portuguese immigrants everywhere, forcing the colonists to flee Congo.

However, the Congolese ruling group frequently competes for the throne, and its subordinate areas are independent. 1709 After the reign of Petro IV, the situation was slightly stable, but the scope of rule was greatly reduced. 1885, the kingdom of Congo was finally divided between the Belgian king and the French and Portuguese colonists.
