Long Distance Trade and the Luba Lomami Empire

The kingdom of Luba Lomami was enlarged and strengthened by the conquest of Kalala Ilunga at an unknown date before the end of the sixteenth century. It became a large but not dominant state. The expansion of Luba Lomami is generally considered to have occurred in the early eighteenth century, as a delayed consequence of the Kalala Ilunga conquest. In this it is said to have been paralleled by the expansion of Lunda. Unlike Lunda, however, it is supposed to have suffered from severe structural deficiencies. These, it has been argued, inhibited its further expansion and, in the mid-nineteenth century, caused it to disintegrate.It is suggested here, however, that the expansion of Luba Lomami did not occur until the late eighteenth or early nineteenth century. This expansion coincided with the extension of the Bisa trading system into the chiefdoms south-east of Luba Lomami and was designed to capture this trade. Later conquests in the south may have been related to the development of Nyamwezi and Bihe trading systems. However, the principal motive for further expansion was the need to capture new sources of ivory and, to a lesser extent, slave-yielding lands. Luba Lomami's success can be attributed to its proximity to the Bisa trade route, its relatively centralized political structures, the availability of viable areas of expansion, and the existence of suitable mechanisms to incorporate the conquered chiefdoms. In the first half of the nineteenth century Luba Lomami subjected most of the area between the Lubilash and Lake Tanganyika and between the forest and the copper belt.In about 1870 the terms of the long-distance trade turned against Luba Lomami. New traders arrived carrying guns. Luba Lomami could not match the new techniques for it no longer had the resources with which to purchase guns. Its own resources of ivory and slaves were exhausted. It could no longer obtain supplies by expansion, for the traders were carving out new states on its periphery, and it was itself becoming subject to slave raids and encroachment. This external pressure weakened the political structures. Rival brothers sought the aid of mercenary traders to promote their cause. The ideological basis of the state was undermined. In a desperate attempt to obtain guns the emperors began to raid for slaves amongst their own people. The empire disintegrated and, in about 1890, the rump of the state became tributary to the trader-state of Msiri.
