Kongo, which had been in contact with the
Portuguese since 1482, held a monopoly on trade with this country. When
Ndongo's king, or
ngola, tried to break this monopoly, this led to war, in which the Bakongo were defeated in 1556. Ndongo was now independent, and directly confronted Portugal's
colonialism. It allied itself with
Matamba against the country in 1590 but was defeated in 1614. Now, Ndongo itself became a target for the slave trade, and its population fled in large numbers to neighbouring states.
Queen Njinga was the daughter of a deceased Ndongo ngola. At the request of Mbandi, the reigning ngola and her brother, she negotiated a peace treaty with the Portuguese. The treaty gave substantial trade and religious advantages to Portugal but delivered Mbandi the throne in Ndongo. After five years, she had to flee from Portuguese troops to Matamba. She became queen of Matamba, a kingdom which was traditionally led by women, and turned it into the most powerful state in the region, and a big exporter of slaves. Matamba, and neighboring Kasanje, had
monopolies in the slave trade, and started falling apart in the 19th century when this trade lost in importance. The rise of a new trade in ivory, rubber and wax, which avoided the old monopolies, reduced the power of central authority in the Ambundu states in this century. The Portuguese defeated Matamba in 1836, and advanced to Kasanje by the middle of the century. Their actual influence, however, was quite limited due to the lack of people, money, and an efficient military. The Ambundu had opportunities to revolt or negotiate liberties. This changed at the end of the 19th century. European countries forced, out of economic, strategic, and nationalistic considerations, a tighter control over African territories. To protect their interests, the Portuguese sent a number of military expeditions into the areas, which they considered to be their colonies, and brought them under actual control. The last Ambundu tribe to be defeated were the NDembo. It took the Portuguese three years to subdue a NDembo revolt in 1910. In 1917 all of their territory was occupied, and they became part of the Portuguese colony of
Angola. == Atlantic Slave Trade ==
