evidence: Among the notable accomplishments of the last group of Bantu immigrants was the creation of political states, or the introduction of centralized systems of government. They established the Maravi Confederacy about 1480. During the 16th century the confederacy encompassed the greater part of what is now central and southern Malawi, and, at the height of its influence, in the 17th century, its system of government affected peoples in the adjacent areas of present-day Zambia and Mozambique. North of the Maravi territory, the Ngonde founded a kingdom about 1600. In the 18th century a group of immigrants from the eastern side of Lake Malawi created the Chikulamayembe state to the south of the Ngonde. [...] In 1891 the British established the Nyasaland Districts Protectorate, which was called the British Central Africa Protectorate from 1893 and Nyasaland from 1907. Under the colonial regime, roads and railways were built, and the cultivation of cash crops by European settlers was introduced. On the other hand, the colonial administration did little to enhance the welfare of the African majority, because of commitment to the interests of European settlers. It failed to develop African agriculture, and many able-bodied men migrated to neighbouring countries to seek employment. Furthermore, between 1951 and 1953 the colonial government decided to join the colonies of Southern and Northern Rhodesia and Nyasaland in the Federation of Rhodesia and Nyasaland, against bitter opposition from their African inhabitants.
