The Portuguese on the Zambezi: An Historical Interpretation of the Prazo System

From the sixteenth century until the coming of the Salazar regime, Portuguese control in the Zambezi basin rested on the prazos da coroa—grants of crown land. Portuguese acquisition of land and jurisdiction began with the establishment of the trading fairs in Mashonaland in the second half of the sixteenth century. Private titles first became common in the seventeenth century, when individual conquistadores, who had obtained concessions from chiefs in return for their help in local wars, sought official titles for their land from the Portuguese crown. In the eighteenth and nineteenth centuries the Crown tried to modify the terms of these grants and alter the character of the institution of the prazos. The prazo-holders successfully resisted these encroachments because their power rested on their followings of African slaves and clients, and on their control of local administration and their family alliances. In the nineteenth century their dependence on their African followings, coupled with increasing inter-marriage, greatly accentuated the African characteristics of the prazos. The most important of the prazo holders became the chiefs of newly emerging African peoples, and adopted the customs and beliefs associated with chieftainship. At the same time the disordered state of the Zambezi following the Ngoni invasions and the growth of the slave-trade eliminated the weaker families and concentrated power effectively in the hands of four major family groupings. The wars waged by the Portuguese government against these families lasted from the 1840s till teh end of the century. In spite of many victories, the internal feuds among the prazo families and the establishment of British administration in Central Africa brought about the end of their dominance. The prazos themselves survived into the twentieth century as units of fiscal and administrative policy.
