The Bomuna people, about the middle of the nineteenth century, came from the bush towns lying in the forest between the Mobangi and the Congo Rivers, and settled on the bank of the main river. Not being a riverine people, they had no knowledge of swimming, and possessed no canoes. They worked their way along the river’s bank from the Monsembe district up-river until they came to the Ejeba stream, near the village of Nyoi, which deep stream they passed by means of a stout cane-creeper that happened to stretch across the water from the overhanging trees. Many passed, and while others were working their way hand over hand along the cane creeper it broke, and thus severed the only means of communication between those on the opposite sides of the stream. Those who found themselves on the eastern side continued their journey, and founded the settlements of Diboko (sometimes called Iboko), now Nouvelles Anvers. Thus the ancient people of Diboko were Bomuna of the tribe of Bobanga, of whom the chief, Mata Bwiki, is the best known to fame, being the head-man who encountered Stanley, and on whose land the Congo Free State built their station of Nouvelles Anvers.
The Bomuna folk left on the western side of the stream settled on suitable town sites in the Mungala Creek above Monsembe, and along the banks of the main river below Monsembe. I knew this branch of the tribe well as being both ignorant and timid in all matters relating to water and canoes.
Between forty and fifty years ago some Libinza Lake people of the tribe of Boloki left their swampy island homes under the leadership of Munyata, and working their way in shallow canoes through the creeks, they came out on the main river near to Moboko. They paddled down the river to the Mungala Creek, which at that time was inhabited by Bomuna people. There Munyata made blood-brotherhood with Munkua, the chief of the Bomuna, and settled there with his people. The Bomuna at that time possessed no spears, but did their hunting and fighting with sharpened sticks, the points of which were hardened in the fire. Munyata presented Munkua with a spear, and received a fine young woman as a return present.
Munyata, the Boloki chief, was apparently a very grasping man, for although he had several wives he coveted more, and was always asking Munkua for one of his. For a time Munkua occasionally gave one; but Munyata let it be known that any woman who ran to him would be retained, and so much was the Boloki chief admired and feared, that one after another of the wives of Munkua escaped to him, until at last only one, his favourite, or principal (nkundi) wife was left, and she was eventually stolen from him by Munyata. So exasperated was Munkua by this treatment that, taking advantage of the first opportunity that offered, he speared Munyata to death.
On the murder of Munyata the Boloki folk came out in crowds from the Libinza Lake to avenge the death of their head-man, and so successful were they with their iron spears against the sharpened sticks of the Bomuna that, although more numerous, the latter gave way before their fierce onslaught. Many escaped, but some took refuge in a high bombax tree. The tree was surrounded by the Boloki, who threatened to starve their enemies to death unless they submitted; and apparently after some palavering the entrapped people had the privilege accorded to them of selecting their own future owners. Thus one would say, “I will take So-and-so as my master,” and on his request being agreed to he would climb down the tree and take his place among the followers of his new master. In this way they divided themselves among their conquerors, and it seems from all accounts they were well treated by the Boloki.
Other contingents of the Boloki came out on to the main river and wrested sites from the Bomuna at Monsembe, Lobengu, Maleli, and Bokomela, and up-river at Bombilinga. In the meantime the Diboko Bomuna had increased in numbers, had become possessed of canoes, and had learned the way to manage them. Their numbers also had been greatly augmented, and their passions inflamed by those who had escaped from the Mungala Creek before, and during, the fight caused by the death of Munyata. These Diboko Bomuna so harassed and fought the Mungala Creek Boloki that numbers of them fled up-river (undoubtedly passing behind the islands to avoid their enemies at Diboko), and established themselves at Mobeka, at the mouth of the Mungala River many miles above Diboko. When first we went to live at Monsembe a very high tree that stood on the bank at the bend of the river was pointed out to me as their post of observation when watching for the Diboko Bomuna.
The Boloki tribe in 1890 possessed the following districts on the north bank of the Congo: Mobeka, at the mouth of the Mungala River, Bombilinga, the Mungala Creek towns, Monsembe, Lobengu, situated in the Mangala Creek, Moleli, Bokomela, and Bungundu. On the south bank they owned Bokumbi, Libulula, and Bolombo. At some time or other the people of Bungundu, Bokomela, Moleli, and Lobengu were called Mangala, and gave their name to the creek in which their principal town was built. Perhaps there was a powerful family called Mangala, and this has been corrupted into Bangala; or the Mungala River was supposed to be the original home of these people, and as mu means place, locality, and ba means people, it was easy to call the people the Bangala. I am rather inclined to the latter reason for the origin of the term among white people, but the natives themselves never used the name Bangala.
Near to Mobeka are the Ngombe people, who are also called Bokumbi, and this tribe in 1908 was becoming mixed with the neighbouring tribes; and as they are being absorbed into them they no longer call themselves Ngombe or Bokumbi, but appropriate the names of the peoples whose language they learn and whose tribal mark they imitate. The hinterland folk of Diboko belong to the Mokulu tribe, and the Bomuna of Diboko to the Bobanga tribe; others in between the Boloki towns down to Bokomela retain their old name of Bomuna. Below Bokomela is the Mbonji tribe that came originally from the bush. The Baloi on the Mobangi River are Boloki from Lake Libinza.
The Libinza Lake is a large sheet of shallow water that drains itself, by the Ngiri River, into the Mobangi, and retains its distinctive colour for many miles. Islands have been slowly made with great labour, and they need constant watching or they will be washed away by the annual floods. The folk drove stakes around any slight elevations shown at low water, and then dug up clay and mud from the bottom of the lake and put inside the stakes, and thus formed an island. These islands are small, but they are numerous, and are often linked together by bridges. There are some large islands, but most of them are small. The lake was thickly populated in the nineties with expert fishermen and saucepan-makers; and they often came out in parties of twenty and thirty to fish with their peculiar box-shaped nets, and to sell their fish, their saucepans, and “fire-pots” to the riverine people for cassava roots. They frequently camped on our beach, and thus we saw much of them. The Libinza folk lived chiefly on plantains, as cassava would not grow in their swampy soil, hence they always exchanged their wares for cassava; and this may have been one of the reasons why Munyata came out from the lake, to establish a centre of exchange for cassava roots.
The tribe near the river always ridicules the tribe behind in the bush, as the Boloki laugh at the Bomuna, and the Bomuna at the Ndobo people further behind. The Boloki are proud of their name and their origin; and the neighbouring tribes acknowledge their courage and endurance, and prefer their friendship to their enmity. The following is an instance of their bravery and the long distances the Boloki men paddled on their raiding expeditions: In the beginning of 1891 there was a big fight in our vicinity, and on inquiring the cause we learned that the reason for the fight between these Boloki towns was this: A year or two before our arrival the Boloki of the Monsembe district paddled over 300 miles up-river and raided the Bopoto riverine towns, carrying off a quantity of loot and a number of captives; and the unsatisfactory division of the spoils culminated in the fight that cost some few lives.
