Their presence in the Zambezi Valley dates back to about 1?600 years ago, their legacy revealed in the decayed housing and storage structures, iron tools and broken pottery that have been found at several sites on the sand escarpments above the Zambezi flood plains.
Initially, these newcomers established semi-permanent communities, growing millet and sorghum and tending cattle, staying in one location for a few seasons before moving on.
Pottery as a Pointer to The Past
Archaeologists often rely on broken pottery to interpret the past. The problem, however, is that there is no simple way of knowing how this reflects historical reality - does the pottery indicate groups of people with a common language, political unity, a common history or simply just the style favoured by a local group of potters and their clients?
This results in conflicting academic interpretations and often considerable vitriolic debate. The Victoria Falls sequence is no exception.
Our current understanding of the Victoria Falls ceramics suggests a changing sequence starting from between the 5th and 8th centuries. A marked change about the 10th century may represent a new migrant population from the west, but could as easily have been in situ evolution of this form. By the 12th century, a new pottery style appears to have spread southward from northern Zambia and was integrated into existing communities.
This probably represents the evolution of the Tonga peoples. Further regional variations have been noted, but their significance remains uncertain.
Traditionally, pottery was a craft practised only by women. According to Shona folklore, only women beyond menopause were allowed to collect the clay used in making pots, because of the ancestral taboo on mixing blood and milk.

Permanent settlements of up to 200 people in each village were invariably sited along the edge of seasonally flooded, marshy watercourses known as dambos.Iron Age historian Joseph Vogel has argued that these dambos were an important feature of village life - wells were sunk in the watercourses, and the soils were rich and fertile so they were ideal for grazing livestock and cultivating crops on a sustained basis.
These communities were probably self-sufficient yet, as Zimbabwean historian Rob Burrett has pointed out, they were probably linked to other communities in the wider region through marriage and the trade of scarce resources such as salt, ivory and copper.
A marked feature of these earlier periods was the extensive use of decoration that characterises their pottery. This style is best known from several sites just west of Livingstone including the site of Dambwa near the international airport.
By the 10th century, however, there seems to have been a depopulation of the area, probably due to climatic shifts that adversely affected agriculture. Hunting and gathering may have assumed a renewed importance as indicated in excavations at Kamangoza and Simbusenga near Livingstone although agriculture would have remained the basis of society. This period was known as the Kalomo Tradition and is characterised by a distinctive, somewhat simplified decorative style.
By the 12th century, there appears to have been a repopulation of the Victoria Falls region in what historians call the Early Tonga Tradition. Vogel believed that early Tonga-speakers moved into the area and formed joint villages with the Kalomo people already present. From this point on, villages were no longer restricted to the edge of dambos and spread out into other habitats.
This may indicate changes in farming methods, which laid the foundation for the manner of community life that has continued in rural Zambia until recent years. A distinctive cultural development that accompanied the Early Tonga Tradition was the manufacture of clay animal and human figurines.
In time, these simple communities evolved into more extensive, centralised political systems with a national kingship supported by a hierarchy of regional chiefs and headmen. These indigenous states were made possible by the ruling elite controlling resources such as cattle, labour, minerals, surplus food production and trade.

The Matabele attacked the Lozi three times during the 1880s in their bid for dominance towards the end of the 19th century. It is said that the Lozi and the Tonga had a hiding place between the third and fourth gorges below the Falls, to which they used to retreat during these attacks, and that all boats were hidden on the north bank of the river.Brett Hilton-Barber and Lee R.
