What is now southern
Malawi was relatively peaceful, prosperous and densely populated by the
Mang'anja people at the time of Livingstone's first visit in early 1859, but was about to become the focus of disruption caused by the large-scale migration of
Yao people. The early Yao migrations from the 1830s involved few people and were relatively peaceful but, whether forced out of their earlier territory in
Mozambique by the
Makua people, by famine, by slave traders, by internal Yao conflicts or some combination of these, larger numbers of Yao moved, firstly, into the
Niassa Province of Mozambique east of
Lake Nyasa and then into the Shire Highlands in the 1850s. These incursions disrupted agriculture and caused widespread famine in the Shire Highland in the early 1860s as the local people abandoned their farms. The Mang'anja were one of the
Maravi cluster of peoples who moved into the Lower
Zambezi and Lower
Shire river valleys before the end of 16th century and coalesced into a number of loosely connected chieftainships which, under pressure from the Portuguese in the Lower Zambezi valley, recognised paramount chiefs with the titles of Lundu, Kalonga and Kaphwiti. These paramount chiefs derived some of their prestige through guardianship of the main shrines of the
M'Bona Cult, and the Lundu kingdom, which included most of the Mang'anja people, controlled the main M'Bona shrine until the early 19th century. At that time, pressure from supposedly subordinate chiefs controlling other shrines and attacks from Afro-Portuguese
chikunda raiding for slaves left the Lundu state with little real power over what had become a loose confederation of local chiefdoms. In the early 1860s, members of Livingstone's expedition or UCMA missionaries described the Mang'anja as being ruled by a hierarchy of chiefs and headmen of varying power and influence. In theory, the Lundu was still the paramount ruler with the power to appoint local chiefs, but his influence was limited. Several major chiefs within the Lundu sphere had more real power than the Lundu himself, although their inability to defend their people against attacks by the Yao and chikunda was beginning to reduce their prestige. As a result of those attacks, some of the Mang'anja in the Shire Highlands were killed or exported as slaves to the Indian Ocean coast, others died of famine or famine-related disease and yet others fled to the Shire valley or the uplands beyond. The loss of population in the Shire Highlands was very great, and much land went out of cultivation and reverted to forest. Even thirty years later at the start of the colonial period, large areas of the Shire Highlands were underpopulated and remained so until the large-scale immigration of
Lomwe people fleeing famine and forced labour in Mozambique at the end of the 19th century. Those Mang'anja remaining in the Shire Highlands were either slave wives or domestic slaves in Yao households or occupied defensible hilltops and inaccessible lakeshores. Once the Makololo had relocated to the Shire valley, they maintained themselves through hunting elephants for ivory and attracted Mang'anja dependents seeking protection, many of whom were slaves liberated from slave caravans who had lost contact with their original homes. The freed women became polygamous wives of the Makololo and the men cultivated farmland seized from its original inhabitants. After the 1864 departure of the UMCA mission, which left behind supplies of arms, munitions and trade goods, the Makololo and their armed dependents attacked local Mang'anja chiefs and established chieftaincies in the present-day
Chikwawa District. Graham-Jolly records the names of 16 original Makololo, but nothing is known of six of them beyond their names, and they were probably absorbed into the local population, losing their Makololo identity. The other ten became chiefs or headmen: two of these, Kasisi and Mloka, were said to be true Makololo rather than coming from subject peoples, and these were the first leaders of the group. The Mang'anja put up little resistance to Kasisi, Mloka and their men and, apart from the deaths of the Lundu and Kaphwiti paramounts and a few followers, the takeover was relatively bloodless. Some Mang'anja chiefs were willing to cooperate with the Makololo against other Mang'anja who were their enemies, whereas the Makololo remained united among themselves and determined to build up their power. At first, Kasisi and Mloka divided the land they had occupied between them, with Kasisi as senior ruler. Kasisi enjoyed reasonably good relations with the Yao which, together with his guns, kept him and his dependents safe from Yao attacks. The Makololo were also some distance away from two other potential enemies. The more powerful and active were the Maseko
Ngoni in present-day
Ntcheu District, and Kasisi set up fortified villages at fords along the Shire River as protection against Ngoni raids. Several Makololo and some of their Mang'anja dependents were installed as headmen in these villages and, on the death of Mloka, Kasisi divided his former territory between three of the original Makololo. Until the death of their leader, Paul Marianno II in 1863, the Afro-Portuguese
chikunda had considerable power and influence in the Lower Shire valley. However, as Marianno's son was then only 8 years old, he required a long minority, during which there were power struggles between the child's mother, his aunt and a prominent chikunda leader, which made it difficult to resist growing power of the Makololo, and the chikunda retreated further down the Shire. ==Later history==
